VJ102MOD - VIIRS/JPSS1 Moderate Resolution 6-Min L1B Swath 750m
VJ102MOD is the short-name of the NOAA-20 — formerly called Joint Polar-orbiting Satellite System-1 (JPSS-1) — platform-derived NASA VIIRS Level-1B 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 Level-1A raw radiances, this product includes calibrated and geolocated radiance and reflectance data, quality flags, and granule- and collection-level metadata. In contrast to a MODIS Level-1B product, which temporally spans 5-minutes, the VIIRS Level-1B calibrated radiances product contains a nominal temporal duration of 6-minutes. The image dimensions of the 750 m swath product measure 3,232 lines by 3,200 pixels.
The variables in the observation data in the NOAA-20-derived VIIRS Level-1B calibration product are almost like those from the SNPP-VIIRS Level-1B (collection-1) except for one major change: The NOAA-20 VIIRS Level-1B calibration product’s quality flags include a detector quality flag with associated masks, their values, and meanings for all the band (I, M, and DNB).
