Version Summary
Version Summary
Version 2 includes 32 new files: 30 ".spread.nc" files which provide the difference in meters SWE from the highest and lowest observation of the component data sets; two climatological files. The climatological files indicate the climatological SWE or climatological spread in SWE for the 30-year period. In Version 1, December 31 was incorrectly dropped during a leap year. The Version 2 data corrected this by removing Feb. 29 from all years and reprocessing. Other changes to the data and metadata include meeting CF (Climate and Forecast) conventions.
Overview
This data set is a daily gridded terrestrial snow water equivalent (SWE) dataset based on five component SWE products:
- GlobSnow combined SWE product (passive microwave/ground-based weather station, version 2)
- ERA-Interim/Land reanalysis SWE product
- MERRA reanalysis SWE product
- Crocus SWE data set: output from the Crocus snowpack model, driven by ERA-Interim meteorology (Brun et al. 2013)
- GLDAS SWE product (version 2) (Rodell et al. 2004; Rodell and Beaudoing 2013)
