Zusammenfassung |
This study analyzes the added value of a regional climate model hindcast with
respect to snow water equivalent (SWE) for Siberia when compared to SWE estimates from forcing
NCEP-R. In addition, we examine
the discrepancies of simulated SWE to several recent reanalysis products
(NCEP-R2
NCEP-CFSR, ERA-Interim). We
apply the regional climate model COSMO-CLM (CCLM) to a 50 km grid spacing using NCEP-R1 as driving force
to obtain a 63 yr (1948 to 2010) gridded dataset of historical SWE.
Simulated regional climate data is necessary because of the absence of
station data in that region. To perform large-scale assessments we use the
satellite-derived daily SWE product of ESA DUE GlobSnow from 1987 to 2010.
Russian station SWE data is used for cross-checking the findings. In January
(mid-winter), the SWE hindcast is in good agreement with GlobSnow, whereas it
overestimates SWE during the melting season. CCLM shows a clear added value
in providing realistic SWE information compared to the driving reanalysis.
The temporal consistency of CCLM is higher than that presented by ERA-Interim
and NCEP-R2. |
