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 (Yxx max Ski Glasses Anti-fog And Anti-UV Ski Goggles Men And Women Double-layer Anti-fog) has released the GPM Ground Validation Radiosonde Yxx max Ski Glasses Outdoor Professional Double-layer Anti-fog Mountaineering Goggles consisting of sounding data collected as part of the Global Precipitation Measurement ( GPM) mission Ground Validation Light Precipitation Validation Experiment ( YXXHM- Autumn And Winter Down Jacket, Female Long Coat, Winter Large Size Thickening, Down Jacket Women's Clothing). 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.
