  • Aqua/AMSR-E L3 AMSR2 Format Sea Surface Temperature (1-Month, 0.1 deg) 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. 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 3 data inputs level 1B and level 2 data and projected to the map in accordance with the specified projection technique (Equi-Rectangular (EQR) or Polar Stereographic (PS)), and then averaged temporally and spatially. These statistical values are computed for observation data on ascending orbit and descending orbit respectively. This product includes monthly mean Sea Surface Temperature (SST) and Static information. The relationship between 6V (or 10V) and SST is calculated by using the complex relative dielectric constant. The physical quantity unit is degree. The following Static information is included: Standard_Deviation: standard deviation value for each pixel. This item is only stored in monthly product. Average_Number: the number of valid physical quantity data (except error and missing) which was used to determine "Geophysical Data". Total_Number: the number of physical quantity data included in the grid (include valid and invalid). The provided format is HDF5. The spatial resolution is 0.1 deg. The statistical period is 1 month. The current version of the product is "Version 8". The projection method is EQR. The generation unit is global.
