GHRSST Level 2P NAVO 1 m Depth Global Sea Surface Temperature version 3.0 from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-21 satellite

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/ghn21-2pn30

The VIIRS_N21-NAVO-L2P-v3.0 dataset produced by the Naval Oceanographic Office (NAVO) derives the 1-meter depth Sea Surface Temperature (SST) from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Joint Polar Satellite System (JPSS)-2 satellite, renamed as NOAA-21 (N21).

Description

N21 was launched on November 10, 2022, the 3rd satellite in the US NOAA JPSS series. VIIRS L2P SST products are derived at the native sensor resolution (~0.75 km at nadir, ~1.5 km at swath edge) using NAVO's Level-2 SST processor version 3.0 (v3.0).

Data contains the global near daily-coverage Sea Surface Temperature at 1-meter depth with 750 m (along) x 750 m (cross) spatial resolution in swath coordinates. Each netCDF file has 768 x 3200 pixels in size, in compliance with the Group for High Resolution Sea Surface Temperature (GHRSST) Data Specification version 2 (GDS2). The data record is available back to Feb. 21 2024.

The L2P SST v3.0 is the first release at PO.DAAC derived from the L2P SST processor v3.0, which was upgraded from the v2.0 with several significant improvements in processing algorithms, including contamination detection, cloud detection, and data format upgrades. The product is comparable with the NPP VIIRS L2P (podaac.jpl.nasa.gov/dataset/VIIRS_NPP-NAVO-L2P-v3.0) and the N20 VIIRS L2P (podaac.jpl.nasa.gov/dataset/VIIRS_N20-NAVO-L2P-v3.0).

It also has similar coverage and quality as the NOAA ACSPO VIIRS L2P SST (podaac.jpl.nasa.gov/dataset/N21-VIIRS-L2P-ACSPO-v2.80).
