Regional climate model hindcasts for Siberia over the last decades based on the COSMO-CLM model driven by NCEP1 and ERA-40, run by Helmholtz-Zentrum Geesthacht

Project: Climate Model Simulations at Helmholtz-Zentrum Geesthacht - Centre for Materials and Coastal Research - The hindcast simulations were conducted as contribution to the Helmholtz Climate Initiative REKLIM (Regional Climte Change), a joint research project of the Helmholtz Association of German research centres (HGF). http://www.reklim.de/ Summary: 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. The output from the model run: Blizzard
