Abstract
Validation results of the atmospheric and radiation blocks of the Regional Climate Model version 4 (RegCM4) coupled with the Community Land Model version 4.5 (CLM4.5) over Western Siberia for 1995-2015 are presented. Model validity was verified by comparing results of RegCM4/CLM4.5 modeling system, driven by the Era-Interim reanalysis, with the global archive of the Climatic Research Unit (CRU3.23) and outgoing longwave radiation (OLR) observed by the Atmospheric Infrared Sounder/Advanced Microwave Sounding Unit (AIRS/AMSU) aboard NASA's Aqua satellite. It was found that for annual T2m air temperature and annual precipitation anomalies model bias is 0.5-0.8 °С and 15- 20 %, respectively. OLR model and the AIRS/AMSU-Aqua observations minimal difference about 1-5 W/m2 is in the summer and fall months. In the winter and spring months this difference may reach 10-15 W/m2.
