Snow Climatology
The snowfall map below was created using a variety of data sets with ArcMap. A base map was constructed using snowfall analysis from the National Operational Hydrologic Remote Sensing Center (NOHRSC) averaging the 2008-2009 to 2018-2019 winter seasons. NOHRSC snowfall data is derived from a set a ground-based, airborne, and satellite snowfall observations. Numerous data points from airports and cooperative observer stations were added to the analysis to yield a more representative 30-year climatology from 1981-2010. Ski sites were also included in the analysis to highlight the considerable variation and more extreme snowfall amounts across the rugged terrain of New Mexico. Click on the image for a larger map.
