Development of Dynamic Snow Density Methodology for GlobSnow SWE Retrieval

In this paper, three versions of spatially and temporally varying snow density fields were implemented using snow survey data from Eurasia and Canada and automated snow observations from USA. Snow density fields were used to improve the baseline GlobSnow v.3.0 SWE retrieval approach. Decadal snow density information, i.e. fields where snow density for each day of the year was taken as the mean calculated for the corresponding day over ten years, was found to produces best results.
