JAXA calls the data that are provided to the public as products. There are three types of products (Level-1, Level-2, and Level-3) according to the processing level, and there are standard products and research products respectively.
For details on each product, please refer to the AMSR Data Catalog.
The data format of AMSR2 standard and research products is HDF5. The AMSR2 format description is available in the "GCOM-W" section of the Globe Portal System (G-Portal). However, for details of QC flags of research products, please refer to the section of each product in the AMSR Data Catalog.
AMSR-E data format descriptions can be downloaded from the EORC Data Distribution for Aqua/AMSR-E.
AMSR-E data format complies with AMSR2 HDF5 format from brightness temperature products (Level-1) ver. 4 and higher-order products (Level-2, Leve-3) ver. 8, so that AMSR2 tools can be used without modification.
The data format for previous versions of Aqua/AMSR-E (brightness temperature products Level-1 ver. 3 or earlier, and higher-order products Level-2, 3 ver. 7 or earlier) and ADEOS-II/AMSR is HDF4.
Data format descriptions can be downloaded from the EORC Data Distribution ( Aqua/AMSR-E, ADEOS-II/AMSR ).
In addition to explanations of the sample program ver. 2, basic knowledge of the GCOM-W satellite and AMSR2 sensor, and instructions on how to install the library are provided. Please use it together with the sample programs and data.
The sample program ver.4 is compatible with AMSR2 products. However, it does not support sea ice motion vector (SIM), so please use the SIM sample program if you wish to use SIM.
The AMSR2 research product, Sea Ice Motion Vector (SIM), is available from two different developers, and the SIM sample programs have corresponding Python code.
