  1. 10GHz sea surface temperature is stored in the second layer of AMSR-E / AMSR2 standard products. Please download the standard products distributed at G-Portal for your use.
  2. Multi-frequency SSTs are stored in the third layers of AMSR2 standard products. Please download the standard products distributed at G-Portal for your use.
  3. The snow depth and soil moisture products are distributed as AMSR-E / AMSR2 standard products, but the latest version processed using the algorithm under development for AMSR3 is distributed as a research product.
  4. AMSR-E brightness temperature data in slow rotation mode are for researchers.

File Format

AMSR2 / AMSR-E research products are in compliance with the HDF5 format of the AMSR2 standard products. However, the sea ice motion vectors (SIM) are in an original format.

For the research products, the quality flag is not described in the format description of the standard products. Please refer to the "Product Summary" of each product in the AMSR Data Catalog.


Tools / Libraries / Sample Programs

Regarding tools, libraries, and sample programs to handle AMSR2 / AMSR-E research products, please refer to the "Resources" page of the AMSR series website.
