CEOP Satellite Datasets ( Aqua > AMSR-E > 3SOILM )

Three scale-types of datasets observed by new generation of remote sensing satellites (including TERRA, AQUA, ADEOS-II) in addition to TRMM and DMSP series, which were providing enhancement of observing capabilities to quantify critical atmospheric, surface, hydrologic and oceanographic data during CEOP time periods are available. 250 km square snapshots of the highest resolution raw radiances (with geographic location, i.e. level 1) remote sensing data at the 35-51 in situ reference sites are archived. ■Mission Aqua (formerly EOS PM-1) ・Applications 6-year nominal mission life, currently in extended operations. Atmosphericdynamics/water and energy cycles, cloudformation, precipitationand radiativeproperties, air/seafluxes of energy andmoisture, sea ice extentand heat exchange with the atmosphere.
