Remote Sensing of the Cryosphere: NASA SnowEx and Multisensor Approaches to Measure Snow Water Equivalent I

Submit an Abstract to this Session



Session ID#: 34131

Session Description:
Snow is of key interest for water resources, natural hazards, water security and weather/climate. Accurate measurement of snow-water equivalent (SWE) enables improved management of freshwater resources. However, current remote sensing techniques underestimate SWE especially in densely-forested areas around the globe, making estimation of SWE challenging. The conveners solicit papers on the measurement of SWE and snow energy balance in different canopy types and densities using a combination of ground, aircraft and satellite instruments. To address the challenges of measuring energy balance and SWE in forested areas, we must determine the sensitivity and accuracy of different remote sensing techniques, such as active and passive microwave, imaging spectrometry and lidar. Papers based on in-situ measurements and modeling are also solicited, to improve our understanding of the retrieval of SWE from space, and to aid in quantifying the accuracy of SWE retrieval using multiple sensing techniques and modeling under varying conditions.
