CanSISE Observation-Based Ensemble of Northern Hemisphere Terrestrial Snow Water Equivalent, Version 2 (NSIDC-0668)
This is the most recent version of these data.
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.
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)
