NASA’s Terrestrial Hydrology Program is planning a multi-year airborne snow campaign called “SnowEx,” beginning the northern hemisphere winter of 2016-2017 and continuing for a total of 5 years. A major goal of SnowEx is to provide the data needed to define a future snow satellite concept, particularly evaluating multiple sensing techniques including lidar, hyperspectral, BRDF, radar, and passive microwave sensors—in concert with models—under a range of snow conditions and confounding factors.
Year 1 will use forests to challenge the sensing techniques. Detailed snow & vegetation ground truth will be collected using a mix of traditional and new methods. Ground-based radars, lidars, VIS/IR spectrometers, and passive microwave sensors are planned as well. SnowEx Year 1 plans are being designed and finalized right now—and very rapidly. Pre-snow ground truth of forest, veg, and soil begin the last week of Sep, 2016 (this month), with the main snow-on campaign in Feb, 2017.
As a key component of Year 1 is the effect of forest on various remote sensing techniques, it is important to characterize the forest appropriately—and we would like to reach out to our Biospheric colleagues for advice—not only for this Year 1, but also with respect to possible synergy with ABoVE activities in the coming years.
The presentation will cover the current plans for SnowEx—where, when, instruments, aircraft, etc. Then, we would love to hear your thoughts.
