Reconstruction of Siberian climate


Klehmet, Katharina; Rockel, Burkhardt

These are two atmospheric hourly hindcasts for Siberia using COSMO-CLM (CCLM) version 4.8_clm_11 with spectral nudging. The hindcast CCLM_sib_NCEP1 covers a period from 1948-2010 and has been performed using NCEP-R1 Reanalysis as global atmospheric forcing for the initialization and regional boundaries. The hindcast CCLM_sib_ERA40 was driven by ERA-40 from 1959-2001.
CCLM uses a rotated grid with 76 x 76 grid points (without the sponge zone) and a grid point distance of 0.44 degrees, the rotated North pole is located at 75 W, 35 N.
In rotated coordinates the model area extends from 14.72 W to 18.28 E, 9.72 S to 27.68 N, in geographical coordinates this corresponds to about 41.2 W to 174.9 E, 42 N to 82.7 N. For all variables lon, lat and the value of the 18:00 time record for the last day is added.

Resolution: grid point distance of 0.44 degrees, hourly hindcast
Parameterisation: Land-surface scheme TERRA-ML (Jacobsen and Heise, 1982), Cumulus convection using the Tiedtke scheme (Tiedtke, 1989), the Runge-Kutta time integration scheme
Boundary conditions: NCEP-R1 and ERA-40 Reanalysis
Input data: For land surface and orographic roughness length: GTOPO30, for land cover: GLC2000, for soiltype: FAO classification, climatological deep soil temperature from CRU (Climate research Unit at the University of East Anglia)
Constants: See 'additional information' Yuspecif_CCLM-ERA40_Sib
The NCEP-R1 driven hindcast simulation covers the period of 1948-2010. The ERA40-driven hindcast simulation covers the period 1959-2001 and does not provide air temperature for different model levels (T).
as consistent as the model is COSMO-CLM version 4.8_clm_11
A multi-layer snow model within TERRA-ML, introduced in a preliminary version by Deutscher Wetterdienst (DWD), was used. Single hourly values of snow variables may be artificial low for single grid boxes due to issues in the used version of the multi-layer snow model with the applied timestep.
