This is the most recent version of these data.
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.
