ADEOS-II/AMSR L2 Sea Surface Temperature dataset is obtained from the AMSR sensor onboard ADEOS-II and produced by the Japan Aerospace Exploration Agency (JAXA).The Advanced Earth Observing Satellite-II (ADEOS-II) was launched on December 14, 2002 (Japanese Standard Time). The objective of ADEOS-II was to acquire data to contribute to international global climate change research, as well as for applications such as meteorology and fishery. ADEOS-II operation on orbit was given up on October 31 2003, because sufficient electric power was not available to maintain operation of the satellite.AMSR observes various physical contents concerning to water (H2O) by receiving weak microwaves naturally radiated from the Earth's surface and atmosphere and also regardless of day or night, the presence of clouds. Those sensors aim at collecting global data for mainly understanding the circulation of water and energy.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.The provided format is HDF4. Spatial resolution is 10 km. The current version of the product is "Version 7". The generation unit is scene(defined as a half orbit).
