Seasonal climatology with the atmosphere model ICON-NWP (1979-2017)

Koehler, Raphael

Dataset
Summary
The data comprises ensemble simulations with the global ICOsahedral Non-hydrostatic atmospheric model ICON (Zängl et al., 2015) version 2.1.0. The model is run with the horizontal resolution R2B5, which corresponds to a grid mesh of approximately 80 km, and with 90 vertical levels up to a height of 75 km. The ICON climatology is created by simulating periods from September to May for the years 1979/80 to 2016/17 (38 years), and each period is simulated by five ensemble members. Thus, yielding a total of 190 nine-month simulations. The ensemble members were generated by shifting the initialisation by ±6h and ±12h. We prescribe mid-monthly sea surface temperatures and sea ice concentrations produced by the Program for Climate Model Diagnosis and Intercomparison for the Atmosphere Model Intercomparison Project (AMIP) experiments of CMIP6 (Durack and Taylor, 2018). Based on the results of Köhler et al. (2021), we use a tuned setup of the subgrid scale orographic (SSO) drag and the non-orographic gravity wave drag scheme, as in particular the stratospheric polar vortex exhibits a more realistic behaviour. The ICON simulations we use in this study are well tested and correspond to the ICONgwd− experiment of Köhler et al. (2021).

The data are grouped by variable and given as daily means on a regular 0.75° lonlat grid. Each folder consists of 190 single files and each file includes one 9-month simulation. The date and time of initialisation are stated in the file name. Pressure-level (PL) data are given on 34 pressure levels. Single-level (SL) data are packed into tar-bundles to avoid a large amount of very small files.
