Dataset contains six geophysical parameters, retrieved from Japan passive microwave radiometer Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) onboard Aqua satellite. Time span covers 6 June 2002 - 4 October 2011. Spatial coverage is global, gridding is not done: data are in swath resolution and organized by ascending and descending paths of original AMSR-E georeferencing (totally about 14 ascending and 14 descending paths). Swath pixel sampling is about 10 km, though the actual spatial resolution is lower and depends on the channels used in the retrievals. The six geophysical parameters are retrieved only over open ocean areas, not covered by ice. They are the following: total atmospheric water vapor content, total cloud liquid water content, sea surface wind speed, based on using high frequency channels, sea surface wind speed, based on using low frequency channels, sea surface temperature and total atmospheric absorption at 10.65 GHz.
