GCOM-W/AMSR2 L1R Brightness Temperature
Listed in NASA Earthdata CMR
GCOM-W/AMSR2 L1R Brightness Temperature dataset is obtained from the AMSR2 sensor onboard GCOM-W and produced by the Japan Aerospace Exploration Agency (JAXA).
Description
GCOM-W was launched by the H-IIA Launch Vehicle No. 21 (H-IIA F21) at 1:39 a.m. on May 18th, 2012 (Japan Standard Time, JST) and inserted into a planned position on the "A-Train" orbit. GCOM-W equipped with AMSR2 takes measurements at multiple microwave frequencies and multiple polarizations of weak electromagnetic waves in the microwave band radiated from the Earthâs surface and the atmosphere.
AMSR2 has swath of 1450 km and 7 microwave bands. The observation data will enable the creation of long-term trustworthy data sets of global physical amount. This product is The Level 1R brightness data which resampled the Level 1B brightness temperature data in proportion to the low-frequency resolution.

Resampling takes place by overlaying the original brightness temperature data with weighted parameters (resampling coefficients) calculated using the Backus-Gilbert Method. The center latitude and longitude of data is adjusted to the 89 GHz A channel receiver data. The provided format is HDF5.
The physical quantity unit is Kelvin. The Sampling resolution are 5-50km. The current version of the product is Version 2.
The Version 1 is also available. The generation unit is scene (defined as a half orbit).
