title: Snow Variables for High Mountain Asia

description: Data associated with the paper: Smith T and Bookhagen B (2020) Assessing Multi-Temporal Snow-Volume Trends in High Mountain Asia From 1987 to 2016 Using High-Resolution Passive Microwave Data. <em>Front. Earth Sci.</em> 8:559175. doi: 10.3389/feart.2020.559175 ( https://doi.org/10.3389/feart.2020.559175 ) This data resource contains one NetCDF file containing high-resolution (3.125km) snow-water equivalent and snow-cover parameters. The named datasets within the NetCDF file are: Annual_SWE_Trend_1987-2016 - Annual average snow-water equivalent trend (1987-2016)<br> DJF_SWE_Trend_1987-2016 - December-January-February average snow-water equivalent trend (1987-2016)<br> MAM_SWE_Trend_1987-2016 - March-April-May average snow-water equivalent trend (1987-2016)<br> JJA_SWE_Trend_1987-2016 - June-July-August average snow-water equivalent trend (1987-2016)<br> SON_SWE_Trend_1987-2016 - September-October-November average snow-water equivalent trend (1987-2016) Annual_SWE_Trend_1987-1997 - Annual average snow-water equivalent trend (1987-1997)<br> Annual_SWE_Trend_1997-2007 - Annual average snow-water equivalent trend (1997-2007)<br> Annual_SWE_Trend_2006-2016 - Annual average snow-water equivalent trend (2006-2016) Annual_Average_SWE - Annual average snow-water equivalent (1987-2016)<br> DJF_Average_SWE - December-January-February average snow-water equivalent (1987-2016)<br> MAM_Average_SWE - March-April-May average snow-water equivalent (1987-2016)<br> JJA_Average_SWE - June-July-August average snow-water equivalent (1987-2016)<br> SON_Average_SWE - September-October-November average snow-water equivalent (1987-2016) Annual_Average_SCA - Annual average snow-covered area (2001-2019)<br> DJF_Average_SCA - December-January-February average snow-covered area (2001-2019)<br> MAM_Average_SCA - March-April-May average snow-covered area (2001-2019)<br> JJA_Average_SCA - June-July-August average snow-covered area (2001-2019)<br> SON_Average_SCA - September-October-November average snow-covered area (2001-2019) The NetCDF file also contains projected x/y coordinates in EASEgrid 2.0, as well as relevant geographic and projection parameters. These data provide high-resolution averages and trends of key snow parameters for analyzing climate change in High Mountain Asia. The underlying data sources are: Brodzik, M. J., D. G. Long, M. A.
