AMSR Data Product Catalog

AMSR data includes observed brightness temperature and geophysical quantities estimated from brightness temperature.

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.

Definition of Processing Levels

Level Contents
Level 0 A data with quality check flags appended.
Level 1A A scene data product that stores the antenna temperature count value converted by the radiometric and geometric correction processing from Level 0 data, the antenna temperature conversion coefficients, etc.
Level 1B A scene data product that stores the brightness temperature converted from the Level 1A antenna temperature using the conversion coefficients.
Level 1R A scene data product that stores the brightness temperature that is spatially resampled from Level 1B to match the center position and size of the Field of View (FOV) of each frequency band at each pixel.
Level 2 A scene data product that stores a physical data retrieved from the brightness temperature at each pixel.
Level 3 A grid data product that stores the brightness temperature or physical data converted using grid processing and temporally statistical processing.
