AMSR-E Brightness Temperature Grids for Cold Land Processes Experiment

Satellite microwave brightness temperature data from the Aqua AMSR-E instrument, gridded for the NASA Cold Land Processes Field Experiment (CLPX) Large Regional Study Area. The dataset is provided by the National Aeronautics and Space Administration. Sources conflict on the last update date, reporting either 2003 or a future date of 2026.

Use Cases

• Modeling snow water equivalent and soil freeze/thaw cycles using gridded brightness temperatures.
• Calibrating and validating land surface models for cold regions.
• Analyzing spatial patterns of microwave emissions over the CLPX study area on geographic (lat/long) and UTM grids.
• Studying the relationship between passive microwave brightness temperature and physical properties of snow and ice.

Strengths

• Data originates from the NASA Aqua satellite's Advanced Microwave Scanning Radiometer-EOS (AMSR-E), a recognized scientific instrument.
• Data is specifically gridded to the defined Large Regional Study Area (LRSA) of a major field experiment (CLPX).
• The dataset's presence across multiple government platforms (Data.gov, NASA Earthdata) indicates its established use in the scientific community.

Limitations

• Critical metadata conflicts exist: the last updated date is reported as both 2003-05-31 and a future date of 2026-03 13.
• No column names, row counts, or specific file sizes are provided by any source, limiting assessment of data structure and volume.
• The license is ambiguously listed as 'other-license-specified' without details.
