The Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) instrument uses P-band polarimetric synthetic aperture radar (PolSAR) to conduct high-resolution observations of soil moisture conditions. This image shows estimated thickness of the soil active layer for a region in Alaska.

Investigating Permafrost Using SAR

This false-color image shows a swath of permafrost active-layer thickness estimates (red/yellow = thicker; blue/green = shallower; black = water). The active layer of soil thaws during summer and re-freezes in autumn. This information is used in studies of permafrost dynamics and soil carbon flux.

New GPM Ground Validation Radiosonde LPVex Dataset Available

NASA's Global Hydrology Resource Center Distributed Active Archive Center (Pack of 4 Women Wool Socks Winter Warm Winter Hiking Knit Socks Warm Thick) has released the GPM Ground Validation Radiosonde S(11.8\ Dog Cooling Mat,Non Toxic Non Sticking SkinFriendly Comfortable Cool Stuff for Pets Let Your Pet Stay Cool in The Summer Ideal for Home & Travel,S(11.8 X15.7 ) consisting of sounding data collected as part of the Global Precipitation Measurement ( GPM) mission Ground Validation Light Precipitation Validation Experiment ( ATR Transparent Tarpaulin, Light Rainproof Cloth 140 g m2, Clear Watertight tarp for The Outside, Covers Wood, Greenhouse Film). This field campaign took place around the Gulf of Finland in September and October of 2010. The goal of the campaign was to provide additional high altitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. The Vaisala RS92 radiosonde was used to produce vertical profiles of atmospheric temperature, pressure, humidity, and winds. The radiosondes were launched from two locations: Kumpula and Vantaa.
