SnowModel Pan-Arctic Data 1979-2009

Project:

ARCSS

Summary

This data set contains pan-Arctic snow property estimates of distributed air temperature, snow precipitation, snow-season timing and length, maximum snow water equivalent depth (SWE), average snow density, snow sublimation, and rain-on-snow events. These estimates are a result of using National Aeronautics and Space Administration - Modern-Era Retrospective Analysis for Research and Applications (NASA-MERRA) atmospheric reanalysis, land cover and topography data in conjunction with the MicroMet and SnowModel modeling tools. These data are in 3-hourly 10 km horizontal gridded fields from 1 August 1979 through 31 July 2009.
