SnowEx20 COSMOS Rover Soil Moisture, Version 1 and
SnowEx20 COSMOS Stationary Soil Moisture, Version 1 data sets, are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
SnowEx20 COSMOS Rover Soil Moisture, Version 1 contains the raw and processed data files from a COSMOS Rover soil moisture probe. The COSMOS Rover uses fast neutron counting to estimate soil moisture over a region up to 300m from the vehicle. Data were collected in one-minute intervals over four days (04 November to 07 November 2019) of driving around Grand Mesa, Colorado. Raw data parameters include atmospheric pressure, temperature, and relative humidity. These raw observations were converted to volumetric soil moisture in the processed data files.

COLUMBIA, Md., Dec. 17, 2020 /PRNewswire/ Scientists at Universities Space Research Association and their colleagues at NASA, University of Texas and other organizations have determined that the slope of the bedrock underneath glaciers around the Greenland ice sheet can either spread ice thinning farther inland or stall it.
Outlet glaciers are essentially rivers of ice flowing over the bedrock and draining into the ocean. They retreat and thin as the climate warms and this thinning spreads farther inland toward the center of the ice sheet.
Recently, by investigating the bed topography of 141 outlet glaciers around Greenland, scientists gained a better understanding of which glaciers could have a significant impact on the Greenland Ice Sheet s contribution to sea level rise in the coming decades. They found that steep bedrock features, called knickpoints , can effectively stall the spread of ice thinning. This often occurs in regions wh
