SnowDATA: Snow Datasets for Arctic Terrestrial Applications

Project Summary
Project CodeALCC2012-02
Project Lead(s) Colorado State University
DescriptionUnderstanding snow conditions is key to developing a better understanding of hydrologic, biological, and ecosystem processes at work in northern Alaska, but these data currently do not exist at spatial or temporal scales needed by end users. To address this need, the Arctic LCC and Alaska Climate Science Center have partnered with researchers from Colorado State University to produce retrospective datasets simulating snow conditions for much of northern Alaska.
Contributing Partner(s) U.S. Geological Survey Alaska Climate Science Center
