Aqua/AMSR-E L2 AMSR2 Format Sea Surface Temperature
Listed in NASA Earthdata CMR
Aqua/AMSR-E L2 AMSR2 Format Sea Surface Temperature dataset is obtained from the AMSR-E sensor onboard Aqua and produced by the Japan Aerospace Exploration Agency (JAXA).Aqua of NASA was launched on May 4th, 2002 in Sun-synchronous sub-recurrent Orbit.
Description
Aqua observes various kinds of physical phenomena related to water and energy circulation from space. Aqua data promoted the research activities for interactions between the atmosphere, oceans and lands, and their effects on climate changes.AMSR-E scans the Earth's surface by mechanically rotating the antenna and acquires radiance data of the Earth's surface.
Each frequency band is monitored by vertical and horizontal polarized wave. It conically scans and keeps an angle of incidence on the earth surface (a nominal of 55 degrees) and accomplishes a swath width of about 1450 km. The AMSR-E reached its limit to maintain the antenna rotation speed necessary for regular observations, and the AMSR-E restarted its observation in slow rotation mode (2 rotations per minute) on December 4, 2012.

However, the AMSR-E reached its limit to maintain the antenna rotation speed necessary for slow rotation mode and it automatically halted its observation and rotation on December 4, 2015.Level 2 product stores the Geophysical quantity from the brightness temperature of level 1 product.This product includes Sea Surface Temperature (SST). The relationship between 6V (or 10V) and SST is calculated by using the complex relative dielectric constant.
The physical quantity unit is degree.Also, the quality flag for each observation point (Pixel Data Quality) is stored.The provided format is HDF5. Spatial resolution is 10 km. The current version of the product is "Version 8".
The generation unit is scene (defined as a half orbit).
