 Data Users Handbook/Format Description



Aqua was developed by NASA to investigate the mechanism of earth environment systems, such as atmosphere, cloud, snow ice, water and vegetation. The development and operation of Aqua are conducted as an international project.
Aqua carries five sensors: Advanced Microwave Scanning Radiometer (AMSR-E) developed by NASDA, Humidity Sounder for Brazil (HSB) developed by INPE, Brazil, as well as NASA's Atmospheric Infrared Sounder (AIRS), Advanced Microwave Sounding Unit (AMSU), Clouds and the Earth's Radiant Energy System (CERES) and Moderate Resolution Imaging Spectroradiometer (MODIS).
EOC will process and provide Aqua data.
