NSIDC archives and distributes daily Level-1A and Level-2A data from the Advanced Microwave Scanning Radiometer (AMSR) instrument that was flown on the Advanced Earth Observation Satellite-II (ADEOS-II) satellite. ADEOS-II, also known as Midori-II, was a Japan Aerospace Exploration Agency (JAXA) satellite used to collect global passive microwave measurements of land, ocean, and atmospheric variables for the investigation of global water and energy cycles. Unfortunately, technical difficulties decommissioned the satellite prematurely and ended the mission just nine months after its launch. Nonetheless, AMSR on ADEOS-II collected pertinent earth observation data in a wide variety of channels ranging from 5 to 50 km resolution.
For a list of available AMSR/ADEOS-II data, refer to the Data Sets page listed in the navigation bar on the left side of this page.
