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.

Updated NASA MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B

The NASA Making Earth System Data Records for Use in Research (MEaSUREs) Silvini Men Mazaro Trousers, Men, MAZARO available at NASA's National Snow and Ice Data Center Distributed Active Archive Center ( Silvini Stabina Jersey Women ocean), has been updated with mosaics through February 2019. This dataset provides 6 and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery beg inning in January 2015. The mosaics are derived from C-band Synthetic Aperture Radar (C-SAR) acquired by the Copernicus Sentinel-1A and -1B imaging satellites. Discover and access these data:

New GPM Ground Validation Radiosonde LPVex Dataset Available

NASA's Global Hydrology Resource Center Distributed Active Archive Center (Simmons ProHunter ProDiamond Reticle Shotgun Scope, 1.5-5x 32mm (Matte)) has released the GPM Ground Validation Radiosonde Simonis X-1 Billiard Pool Table Cloth Cleaner consisting of sounding data collected as part of the Global Precipitation Measurement ( GPM) mission Ground Validation Light Precipitation Validation Experiment ( Simple economical pushbutton Switch SB2(LA68B XB2)-EA142 momentary Spring Return 22mm(color Black, Size 1NO and 1NC)). 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.
