Meteorological Office Hadley Centre, Technical Note 73, March 2007 Aerosol Emission And Conc Aerosol Emission and Concentration Emissions for the sulphur cycle include emissions of ammonium sulphate aerosol precursors: sulphur dioxide and dimethylsulphide. For sulphur dioxide, anthropogenic emissions are split into surface and chimney-level emissions. Natural emissions from volcanoes are provided as a 3D field. DMS emissions are provided by the ocean biogeochemistry scheme over the ocean, and provided through a dataset over land surfaces. All sulphur-cycle emissions are expressed in term of mass of sulphur within the model. For black-carbon and organic-carbon aerosols from fossil-fuel and biofuel emissions, emissions are provided at near-surface level. These emissions are expressed in term of mass of carbon. For biomass-burning aerosol, emissions are provided as two fields: surface emissions, and high-level emissions. The latter field is homogeneously distributed across the boundary layer. Biomass emissions are expressed in term of mass of carbon. Emissions for sea-salt and mineral dust aerosols are computed interactively from the modelled meteorology and soil properties by their respective schemes. The climatology of monthly-averaged mass-mixing ratios of secondary organic aerosol from terpene emissions was derived from the chemistry-transport model STOCHEM (Derwent et al., 2003). 2D emissions: All emission fields are provided as monthly means, which are time interpolated by the model every 5 days. Sulphur dioxide emissions are derived from sector-based emissions datasets for IPCC AR5 (Lamarque et al., 2009). Emissions for all sectors are considered surface emissions, except for energy emissions and half of industrial emissions which are considered chimney-level emissions. Emissions for land-based dimethylsulphide are taken from Spiro et al. (1992). Anthropogenic emissions for black carbon and organic carbon are from the sum of all sector-based emissions in the IPCC AR5 dataset. They are emitted in the second level of the model (near-surface emissions). Anthropogenic emissions for biomass-burning aerosol are the sum of IPCC AR5 emissions for black and organic carbon from biomass-burning emissions. Grass fire emissions are assumed to be surface emissions, while forest fire emissions are distributed homogeneously across the boundary layer. Emissions based on interactive schemes: Sea-salt and mineral dust aerosol emissions are computed interactively depending on modelled near-surface wind speeds and soil properties (Jones et al., 2001; Woodward, 2001). The only 3D aerosol-related emissions used in the model are natural emissions of sulphur dioxide from background volcanoes (Andres and Kasgnoc, 1998). Aircraft emissions of aerosol precursors or primary [aerosols] are not included in the model. 2D-Emissions 2D-Emissions Method Method interactive other SourceTypes SourceTypes anthropogenic bare ground other sea surface InteractivEmittedSpecies InteractivEmittedSpecies mineral dust, sea-salt, ocean-based DMS MethodCharacteristics MethodCharacteristics CMIP5 emission timeseries (monthly from linear interpolation of decadal means) EmittedSpecies EmittedSpecies sulphur dioxide, ammonia, fossil-fuel black carbon, fossil-fuel organic carbon, biomass-burning other sources other sources natural emissions from land surface of DMS and vegetation emissions 3D-Emissions 3D-Emissions Method Method prescribed (climatology) SourceTypes SourceTypes other volcanoes ClimatologyType ClimatologyType monthly ClimEmittedSpecies ClimEmittedSpecies sulphur dioxide from degassing volcanoes, secondary organic aerosol Concentrations Concentrations PrescribedLowerBoundary PrescribedLowerBoundary N/A PrescribedUpperBoundary PrescribedUpperBoundary N/A PrescribedWithinAtmos PrescribedWithinAtmos biogenic aerosol Chris Jones Met Office Hadley Centre, Fitzroy Road, Exeter, Devon, UK, EX1 3PB chris.jones@metoffice.gov.uk http://www.metoffice.gov.uk/research/our-scientists/climate-chemistry-ecosystems/chris-jones Chris Jones UK Met Office Hadley Centre MOHC Chris Jones Met Office Hadley Centre, Fitzroy Road, Exeter, Devon, UK, EX1 3PB chris.jones@metoffice.gov.uk http://www.metoffice.gov.uk/research/our-scientists/climate-chemistry-ecosystems/chris-jones Chris Jones UK Met Office Hadley Centre MOHC Andres 1998 Andres, R.J. and Kasgnoc, A.D.

The model also includes a fixed monthly climatology of mass-mixing ratios of secondary organic aerosols from terpene emissions (biogenic aerosols). All aerosol species, except sea-salt and biogenic aerosols, are advected using the tracer advection scheme and undergo wet and dry deposition. Wet deposition accounts for re-evaporation of precipitation (Bellouin et al., 2007). All aerosol species exert a direct effect (scattering and absorption of shortwave and longwave radiation) and thereby also a semi-direct effect (impact on atmospheric temperature and cloud profiles of aerosol absorption). All aerosol species, except black carbon and mineral dust, also contribute to both the first and second indirect effects on clouds, modifying cloud albedo and precipitation efficiency, respectively. The version of the sulphur cycle included in HadGEM2 is described in Jones et al. [2001] and Roberts and Jones [2004] with further improvements described hereafter. The sulphate scheme is a modal scheme where the free aerosol is assumed to have a log-normal size distribution in the Aitken and accumulation size ranges, which include particles with a radius less than 0.05 and 0.5 m, respectively. Sulphate aerosol may also be in a dissolved mode where layer clouds are present, thus affecting the cloud droplet size and exerting first and second indirect effects (modification of cloud albedo and precipitation efficiency, respectively). The sulphur cycle in HadGEM2 also includes improvements described by Bellouin et al. [2007]: condensation of sulphuric acid from dry oxidation of sulphur dioxide and dimethysulphide, and conversion from Aitken to accumulation mode particles by condensation. In addition, the oxidation of SO2 and DMS is now using oxidant concentrations (OH, HO2, H2O2, O3) provided by the interactive tropospheric chemistry scheme and depleted oxidants are fed back to the chemistry (alternatively, oxidant concentrations can be prescribed). Emissions of dimethylsulphide from the ocean is provided by the ocean biogeochemistry scheme. The sea salt scheme is a simple diagnostic scheme depending on wind speed and height above the surface to determine the number concentration of sea salt particles in two size modes (Jones et al., 2001). Schemes for black carbon from fossil-fuel emissions (Roberts and Jones, 2004), biomass-burning, and organic carbon from fossil-fuel emissions (Collins et al, 2008) include modes for freshly emitted particles that gradually age into another, more hygroscopic mode; there is also a mode for aerosols that have become incorporated into cloud droplets. Black carbon is considered to be slightly hygroscopic, only becoming incorporated into cloud droplets by diffusion, whereas organic carbon and biomass-burning aerosols are considered to act as cloud condensation nuclei. The mineral dust scheme is based on Woodward (2001) with further improvements made to the dust emission scheme (described in Collins et al, 2008): changes to values of the impact threshold friction velocity and parameterisation of the effect of soil moisture. The modelled horizontal flux includes a wide size range of particles from .06 to 2000 microns in 9 bins. Vertical flux is calculated for particles up to 60 microns in 6 bins, the size distribution following that of the horizontal flux in this range.

HadGEM2-ES includes interactive modelling of atmospheric aerosols, driven by surface and elevated emissions and including tropospheric chemical processes as well as physical removal processes such as washout. The aerosol species represented in the model are sulphate, black carbon, biomass smoke, sea salt, organic carbon, mineral dust and a biogenic climatology. The atmospheric component has a horizontal resolution of 1.25 degrees of latitude by 1.875 degrees of longitude with 38 layers in the vertical extending to over 39 km in height.

Quarterly Journal Royal Meteorology Society, 131, 1759-1782. Atmos Convect Turbul Cloud Atmospheric Convective Turbulent Cloud The convection scheme is based on the mass flux scheme of Gregory and Rowntree (1990) but with major modifications. The scheme is explicitly coupled to the boundary layer scheme, and cumulus convection is similarly diagnosed using the mean humidity profile. If cumulus convection is diagnosed, then the boundary layer scheme is capped at the convective cloud base. The convection scheme is then triggered from the lifting condensation level in order to parameterize transports from cloud base upward. Deep and shallow convection are diagnosed separately and different thermodynamic closures are applied. In shallow convection the closure is based on Grant (2001); for deep convection a CAPE closure is used, based on Fritsch and Chappell (1980). A convective momentum transport (CMT) parameterization is used for both deep and shallow convection, based on a flux-gradient relationship obtained from the stress budget. A cloud-base closure for CMT is used, based on the assumption that large-scale horizontal pressure gradients should be continuous across cloud base. Entrainment and detrainment rates for shallow convection are parameterized as in Grant and Brown (1999). The radiative effects of convective anvils are represented by specifying a vertically varying convective cloud amount (Gregory 1999). The model includes adaptive detrainment parametrization to produce smoother mass-flux profiles and more realistic diabatic heating profiles. In addition the depth criterion for shallow convection has been removed to allow shallower clouds to rain provided their water content is sufficiently high.

Atmos Cloud Scheme Atmospheric Cloud Scheme The large-scale cloud scheme for liquid cloud is that of Smith (1990), in which cloud water and cloud amount are diagnosed from total moisture and liquid water potential temperature using a triangular probability distribution function. The width of this distribution is diagnosed from the variability of the moisture and temperature of the surrounding grid points. A representation of the difference between cloud area fraction and cloud volume fraction is made by subdividing a single model layer into three. HadGEM1 and later models introduced an updated version of the Wilson and Ballard (1999) microphysics scheme. Transfers between water categories (ice, liquid water, vapor, and rain) are calculated based on physical process equations using particle size information.

It facilitates the use of satellite data to evaluate models in a process-oriented and consistent way. The flexibility of COSP makes it suitable to be used in any type of numerical model, from high-resolution cloud-resolving models to coarse-resolution models like the GCMs used in climate modeling, and the scales in between used in weather forecast models. The fact that COSP includes several simulators under the same interface facilitates the implementation of a range of simulators in models. A general description of COSP is given in Bodas-Salcedo et al. (2011). The following instrument instrument simulators are included:CloudSat (Haynes et al., 2007), CALIPSO (Chepfer et al., 2008), ISCCP (Klein and Jakob, 1999; Webb et al., 2001), MISR (Marchand and Ackerman, 2010), and MODIS.

The actual gravity wave drag is that due to air flowing over orography; it is deposited where wave breaking is diagnosed (typically in the lower stratosphere). The remaining drag (about 80 per cent of the total) is attributed to flow around the orography and is deposited uniformly between the surface and the subgridscale orographic height.

It includes absorption by CO2, H2O, O3, O2, N2O, CH4 and CFCs. The longwave band from 1200 to 1500 cm-1 has been split at 1330 cm-1 in order to better represent the overlap between CH4 and N2O. Gaseous absorption is based on the updated High-Resolution Transmission (HITRAN) 2000 database (Rothman et al., 2003). The water vapour continuum is version 2.4 of the Clough-Kneizys-Davies (CKD) formulation (Clough et al., 1992) and has been included in the shortwave region. Treatment of the effects of non-spherical ice cloud particles are determined using the parameterization by KristjA?nsson et al. (2000). The sea surface albedo is based on the functional form of Barker and Li (1995), modified in the light of aircraft data, and the land-surface albedo is described by Essery et al. (2003). The direct (scattering and absorption of radiation) and indirect radiative effects of aerosols is included.

They are initialised with a snow depth of 50,000 mm of water equivalent. Further ablation or accumulation has an impact on sea level. Runoff follows the river routing scheme and enters the oceans at predefined river outflow points. Calving at the coastal boundaries is simulated through a fresh water flux to the ocean evenly distributed over the area of observed icebergs in both hemispheres. The value of the freshwater flux is calculated to exactly balance the time mean ice sheet surface mass balance over the preindustrial control simulation.

This allows tiling of land surface heterogeneity using nine different surface types. A separate surface energy balance is calculated for each tile and area-weighted grid box mean fluxes are computed, which are thus much more realistic than when a single surface type is assumed. In addition, vegetation leaf area is allowed to vary seasonally, providing a more realistic representation of seasonal changes in surface fluxes. Tiling of coastal grid points allows separate treatment of land and sea fractions. This in combination with the increased ocean model resolution greatly improves the coastline, particularly in island regions.

Land Surface Albedo Land Surface Albedo A bulk albedo is used for each of the surface types within the tile scheme. Non vegetation surfaces have a fixed specified snow free albedo. For vegetation the albedo is a combination of the bare soil albedo and the vegetation albedo, using Bear's law to determine the fraction of bare soil. The overall albedo then depends upon the amount of snow, varying between the snow free albedo and a specified deep snow albedo according to the depth of snow (Essery et al. 2001).

This is extended to include thermal inertia for the surface and weakening of the coupling to the underlying soil through radiative processes (Essery et al. 2001). Surface heterogeneity is modelled using the tile approach, with a separate surface energy balance calculation for each tile. The temperature change associated with the outgoing longwave radiation is taken into account in the surface energy balance, but the net change to the radiative balance is not applied throughout the atmosphere. Instead it is assumed that the small changes to the longwave radiation pass through the atmosphere and are added to the top of atmosphere balance through an additional diagnostic. The surface is implicitly coupled to the atmosphere using the method of Best et al. (2004).

This layer is merged with the first soil layer in such a way that if the total depth of snow is less than the thickness of the first soil layer, then the thermal properties become a linear weighting of those from the snow and soil. If the snow depth exceeds the first soil layer thickness, then this layer can increase in thickness and adopts only the snow thermal properties (Essery et al. 2001).

This allows for the deeper layers to become saturated and a water table to form. Deep run-off is lost through lateral flow below the water table. Excess (supersaturated) soil water (e.g. through snowmelt) is now drained into the soil layer below instead of simply run-off from the top layer. This increases soil moisture in the lower soil layers and so helps to reduce the water stress on vegetation following snowmelt in Northern Hemispheric continents.

For HadGEM2-A they are specified. The representation of photosynthesis is that of Collatz et al. (1991) for C3-type photosynthesis and Collatz et al. (1992) for C4-type photosynthesis, as described in Cox et al. (1999). Photosynthesis is also directly sensitive to the leaf nitrogen concentrations (specified) and the leaf temperature. The phenological status alters the leaf area index (LAI) of the canopy and is soley a function of leaf temperature (with pre-specified tolerances to low temperatures) and includes the effects of leaf dropping and budburst in a way corresponding to a chill-day parametrization. It also includes a representation of the vertical profiles of light and nitrogen through the canopy (Mercardo et al., 2007).

The new Total Runoff Integrating Pathways (TRIP) dynamic river routing scheme (Oki and Sud 1998) advects runoff along prescribed channels using an embedded 1degree x 1degree river transport submodel. All rivers flow with an effective velocity of 0.4 m/s and a meander ratio of 1.4. River outflow to the ocean is included. Ancillary files specify 'inland basins' in which the river flows into an inland delta and the moisture enters the soil column. The model also allows for inland basins to be defined seperately, and spreads water proportionately over the river outflow points.

In the model, only the surface CH4 concentration were forced to follow the prescribed trajectory, but CH4 concentrations above the surface were calculated interactively, and the full 3D field was then passed to the model's radiation scheme. As CH4 concentrations were only prescribed at the surface, CH4 in HadGEM2-ES above the surface is free to evolve a non-uniform structure and may differ from the prescribed, well-mixed historical concentrations. The impact of passing a full 3D CH4 field from UKCA to the radiation scheme rather than passing a uniform concentration everywhere was evaluated in a present-day atmosphere-only configuration of the HadGEM1 model (Johns et al., 2006; Martin et al., 2006).

In the model, only the surface CH4 concentration were forced to follow the prescribed trajectory, but CH4 concentrations above the surface were calculated interactively, and the full 3D field was then passed to the model's radiation scheme. As CH4 concentrations were only prescribed at the surface, CH4 in HadGEM2-ES above the surface is free to evolve a non-uniform structure and may differ from the prescribed, well-mixed historical concentrations. The impact of passing a full 3D CH4 field from UKCA to the radiation scheme rather than passing a uniform concentration everywhere was evaluated in a present-day atmosphere-only configuration of the HadGEM1 model (Johns et al., 2006; Martin et al., 2006). It was found to cool the extra-tropical stratosphere by 0.5-1.0 K, thereby reducing the warm temperature biases in the model (O'Connor et al., 2009).

With the changes across the spectral bands the Rayleigh scattering and ozone absorption properties are also varied. The TSI data used for the historic period were recommended by CMIP5 (Lean et al., 2009 -L09; SOLARIS 2009) and are created from reconstructions of solar cycle and background variations in TSI. The annual mean TSI was processed to force the mean of the 1700-2004 period to be the same as the model control solar constant value (1365 Wm-2). dataFormatType http://proj.badc.rl.ac.uk/svn/metafor/cmip5q/trunk Solar Irradiance dataFormatType http://proj.badc.rl.ac.uk/svn/metafor/cmip5q/trunk SOLARIS 2009 http://www.geo.fu-berlin.de/en/met/ag/strat/forschung/SOLARIS/Input_data/CMIP5_solar_irradiance.html CMIP5 solar irradiance Total Solar Irradiance CF http://proj.badc.rl.ac.uk/svn/metafor/cmip5q/trunk Total solar irradiance in Wm-2 753a78ee-e2ac-11df-b3ef-00163e9152a5 1 Metafor Questionnaire 2012-04-23T18:12:16.047837 ocean_DMS Used for the HadGEM-A simulations.

The key features of the N96L38 grid configuration, which is utilised by the Met Office Hadley Centre HadGAM1 and HadGAM2 atmosphere models, are as follows. The grid is logically rectangular and dimensioned (i=192, j=145, k=38), where i = longitude, j = latitude, k = level. Horizontal grid cell size is 1.875 degrees in longitude by 1.25 degrees in latitude. Vertical levels are terrain-following for levels up to k=29 and constant thickness above that level. Grid staggering (i.e. between the sub-grids used by scalar (physics) and vector quantities) is based upon the Arakawa-C grid configuration. Array indexing in the latitude direction starts at the south pole. For an unrotated grid mesh, longitude (i=0.5) corresponds to Greenwich meridian. In the Unified Model, the north and south poles coincide with the bounding half-integer j planes, i.e. j=0.5 and j=M-0.5. P-points and u-points exist at the poles, but not v-points. At the poles all values of P variables are set equal. Likewise for scalar variables rho, theta, m, w. Johns_2005 Johns T.C., et al. (2005).

Horizontal properties: The N96 Grid represents the 192-column horizontal coordinate system utilised within the Met Office Hadley Centre HadGAM1 and HadGAM2 atmosphere models. This grid defines the horizontal locations of the physics (P) variables computed by these atmosphere models. The locations of U variables are offset by one-half of a grid cell to the east of P grid locations. The locations of V variables are offset by one-half of a grid cell to the north of P grid locations.
