Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/viirs/vj202mod.002
Description
The VIIRS/JPSS2 Moderate Resolution 6-Min L1B Swath 750m, short-name VJ202MOD is the Joint Polar-orbiting Satellite System-2 (JPSS-2/NOAA-21; referred to hereafter as J2) platform-derived NASA Visible Infrared Imaging Radiometer Suite (VIIRS) L1B calibrated radiances product that comprise sixteen moderate-resolution or M-bands, which have a spatial resolution of 750-meters at nadir. These M-bands comprise eleven reflective solar bands (RSB) and five thermal emissive bands (TEB).
Each of the M-bands has 16 detectors in the along-track direction with 16 rows of pixels per scan that provide a 750-m resolution. Ranging in wavelengths from 0.402 µm to 12.49 µm, the M-bands are sensitive to visible, near-, shortwave-, mediumwave-, and longwave-infrared wavelengths. Derived from the NASA VIIRS L1A raw radiances, this product includes calibrated and geolocated radiance and reflectance data, quality flags, and granule- and collection-level metadata.

The J2 VIIRS radiometric calibration Level-1B reprocessing includes a few calibration updates for the reflective solar bands (RSB), but no significant changes for the day-night band (DNB) or thermal emissive bands (TEB).
