AMSR-E Validation Data

Validation Campaigns for the AMSR-E Sensor on the NASA Aqua Satellite

DAAC Home


Overview

The AMSR-E validation effort addresses data quality through several comprehensive calibration and validation programs. These programs characterize and document the accuracy and precision of AMSR-E observations and their derived products.

Pre-launch activities demonstrated the stability of the instrument software and began to demonstrate the validity of the retrieved products with in situ ground truth data. Post-launch efforts concentrate on validating the retrieved products using in situ data.

The validation effort includes three types of products: cryospheric data, including snow, ice, and sea ice; rainfall data; and soil moisture data. For complete information about the program, please see the AMSR-E Validation Plan (PDF file, 24.7 MB).


Campaign Coverage

The AMSR-E Validation campaign schedule shown here demonstrates the broad range of these calibration studies in terms of both temporal and geographic coverage.
