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 (YUNDONGFU Sun predection clothing WHITE Fishing Clothing Outdoor Quick-Drying Anti-UV Breathable Sun Predection Shirt Coat Summer Man Sport Clothes) has released the GPM Ground Validation Radiosonde YunNR Figure Skating Dress for Girls Women Ice Skating Competition Performance Costume Rhinestone Handmade Professional Breathable Skating Wear Long Sleeves consisting of sounding data collected as part of the Global Precipitation Measurement ( GPM) mission Ground Validation Light Precipitation Validation Experiment ( YunNR Handmade Rhinestone Figure Skating Professional Competition Clothing Women's Girls' Ice Skating Dresses Long Sleeve Black Halo Dyeing Spandex). 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.
