1. A New Global Cryosphere Map
Goal: Update the classic cryosphere map below with new data, more data, and interactive capabilities.

Downloaded four different snow coverage years (1995, 2010, 2013, 2017), and could get none to open in ArcMap; Must look for data elsewhere
Downloaded the multi year mean data, imported into ArcMap with Float-to-Raster after building a .hdr file based on readme file. Put "0" into No_Data value. but that made a 16-bit image and lost the values so used QGIS to do the export and build a color table based on the .png file

Permafrost and Seasonally Frozen Ground
Permafrost Zonation (PERZONES) is provided as ESRI shapefile. Permafrost zonation is the permafrost probability fraction reclassified to standard permafrost zonation of continuous, discontinuous and sporadic permafrost. The zone borders were simplified and smoothed.
