Abstract:
The Central Asian Snow Cover from Hydrometeorological Surveys data are based on observations made by personnel for three river basins: Amu Darya, Sir Darya, and Naryn. These observations include end of month snow depth, snow density and snow water equivalent. Only snow depth is included for additional snow points measured by helicopter landings. Temporal coverage varies for each snow point, with the longest station record extending from 1932 through 1990. Data were provided to NSIDC by the State Hydrometeorological Service (Russian acronym SANIGMI) in Tashkent, Uzbekistan. Development of this data set was funded by the NOAA Environmental Services, Data, and Information Management (ESDIM) program, through the NOAA/NESDIS National Geophysical Data Center (NGDC).

Quality
This data set is based on hand-digitized analog records. Degradation of the original records and human error can cause missing or inaccurate data values. These data were examined by the principal investigator and compared to expected climatological values to identify and remove large errors before being archived by NSIDC.
