Level-1b calibration The Level-1b calibration products contain the calibration and background measurements,
including annotation data, as well as any calibration data that are derived from radiance and irradiance
measurements. For each data granule, there is a data product for each of the two modules, UVN and
SWIR. The calibration products are the main input for the calibration processors that will use these
products for generating updates to the calibration key data and for generating trending and monitoring
products. |
