Part 1 of a two-part webinar in which we share Snowpack Monitoring in the Rocky Mountain West: A User Guide. Guest speakers Karl Wetlaufer (NRCS) and Jeff Deems (CIRES) will discuss the details of snowpack observations, both in situ and remotely sensed: Where, how, and what data are collected, how are they organized, and how are they accessed? Snowpack Monitoring in the Rocky Mountain West: A User Guide is a reference for water managers, decision makers, forecasters, researchers, and others who use, collect, and produce snow information. The guide outlines the fundamental characteristics of the snowpack, the processes that drive its variability over time and space, and the challenges of sampling such a dynamic resource. It describes SNOTEL, snow course, and other networks of point observations and summarizes products that provide spatial estimates of snowpack. Finally, it provides practical guidance on accessing, interpreting, and applying snow data.
