NSIDC DAAC will archive and distribute data products from the NASA SnowEx campaigns focusing on collecting snow data in forested regions with airborne multi-sensor and in situ validation observations.  Year 1 snow measurements, scheduled to occur in February 2017,  will take place in Grand Mesa, Colorado, with a secondary site located at Senator Beck Basin, Colorado. The mission will utilize a suite of airborne instruments such as Lidar, SAR, Passive Microwave, Multi-spectral/hyperspectral VIS/IR, and others, to identify the optimum combination of sensors needed to retrieve Snow Water Equivalent (SWE) in forested areas.

About the Project

The NASA HQ/Terrestrial Hydrology Program, with contributions from participating scientists and researchers, has initiated a multi-year airborne and ground campaign to collect observations to enable studies for snow satellite mission designs, with the following objectives:

• develop/test algorithms for measurement of SWE in forested and non-forested areas by providing multi-sensor observations of seasonally snow-covered landscapes
• develop/test energy balance models and snow distribution models of beneath-canopy snowpack using appropriate field measurements
• explore how best to combine sensing technologies with modeling and data assimilation methods to produce the most accurate products
