The information about DSCOVR_NISTAR_L2_FLX_01 in the ASDC's website:
https://asdc.larc.nasa.gov/project/DSCOVR is only include La and Lb grade, and the detailed information about the DSCOVR_NISTAR_L2_FLX_01
cannot find in it. so i hope you can submit more information about about the DSCOVR_NISTAR_L2_FLX_01 .

Please be advised that the actual L2 data product is generated by NASA Langley, based on the L1A/L1B data product generated by us and the spectral irradiance distribution of the Earth obtained from EPIC. At the moment, there is no released documents related to the L2 product from Langley. However, you may find useful information in the search articles authored by Dr. Wenying Su:

Determining the Daytime Earth Radiative Flux from National Institute of Standards and Technology Advanced Radiometer (NISTAR) Measurements

Determining the Shortwave Radiative Flux From Earth Polychromatic Imaging Camera

Also, please note that the calibration (e.g., the SW band filter transmittance) used in this released L2 data is outdated, which increases the absolute scale of the SW channel by approximately 5 %. The 2017/2018 L2 data with updated calibrations has already been produced by NASA Langley and will be released in the future.
