Evaluation of AMSR-E snow depth product over East Antarctic sea ice using in situ measurements and aerial photography
The Antarctic Remote Ice Sensing Experiment (ARISE) was conducted in the East Antarctic sea ice zone during SeptemberOctober 2003. A key objective of this program was the acquisition of in situ measurements suitable for evaluating the EOS Aqua Advanced Microwave Scanning Radiometer (AMSR‐E) snow dep...

The Antarctic Remote Ice Sensing Experiment (ARISE) was conducted in the East Antarctic sea ice zone during SeptemberOctober 2003.

A strategy is presented for comparing snow thickness measurements over spatial scales ranging from point measurements to satellite pixels. In situ measurements of snow thickness were taken across eight Lagrangian grid cells defined and tracked using an array of drifting buoys. These data are coupled with ice‐type analyses from digital aerial photographs to calculate area‐averaged snow thicknesses that are compared with the AMSR‐E derived snow thickness product.
