VIIRS/JPSS2 Imagery Resolution 6-Min L1B Swath 375m NRT
Listed in NASA Data Portal
The VIIRS/JPSS2 Imagery Resolution 6-Min L1B Swath 375m Near Real Time (NRT), short-name VJ202IMG_NRT is platform-derived NASA VIIRS L1B calibrated radiances product that comprises five image-resolution or I-bands, which have a 375-meter resolution at nadir.
Description
These I-bands comprise three reflective solar bands (RSB) and two thermal emissive bands (TEB). Each of the I-bands has 32 detectors in the along-track direction with 32 rows of pixels per scan that offer a resolution that is twice finer than that of the moderate (M) and Day-Night bands (DNB).
Ranging in wavelengths from 0.6 µm to 12.4 µm, the I-bands are sensitive to visible/reflective, 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. In contrast to a MODIS L1B product, which temporally spans 5 minutes, the VIIRS L1B calibrated radiances product contains a nominal temporal duration of 6 minutes.

The image dimensions of the 375-m swath product measure 6464 lines by 6400 pixels. 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).
