Brief description

The NOAA20/VIIRS Sea Surface Temperature product is derived from VIIRS 11 and 12 micron spectral bands according to the algorithm described at https://oceancolor.gsfc.nasa.gov/atbd/sst/. This is not a GHRSST-quality product, and demanding applications requiring a high standard of accuracy should consider using one of the IMOS GHRSST products in preference. The VIIRS SST is nevertheless useful primarily because it is measured at the same time as the water leaving radiances used to derive the optical properties (eg chl). This means it is both contemporaneous, and has a matching cloud mask, so it is valuable for applications that seek to combine both SST and optical properties (ie Net Primary Productivity variants). The data set provided here matches the Chl_oci product in temporal and spatial extent. This SRS dataset covers waters around Australia.

Lineage

Statement: The radiometric sensitivity of the VIIRS sensor is evolving continuously during its mission and is monitored regularly by NASA. The SeaDAS software uses tables of calibration coefficients that are updated periodically. From time to time upgrades to the algorithms and/or the format of the calibration tables are required, in which case a new version of SeaDAS is released. These data were initially being produced using SeaDAS 8.x and more recently, with SeaDAS 9.x. The data are produced by combining the near real time (nrt) data stream from all the available direct broadcast reception stations in Australia with delayed-mode data from NASA in the US. The data have been remapped from satellite projection into a geographic (Latitude/Longitude axes) projection (0.01 degree sampling) and are presented as a sequence of daily mosaics covering the region (80 <= Longitude <= 180, -60 <= Latitude <= +10) formatted as CF-compliant netCDF files. It should be noted that the data are not processed until the definitive spacecraft ephemeris becomes available, usually 12-24 hours after the overpass. This means that the geolocation should be of a uniformly high standard. The filenames are of the form J.P1D.yyyymmddThhmmssZ.aust.sst.nc, where 'J' denotes NOAA20/VIIRS, 'yyyymmddThhmmssZ' is the GMT date of the mosaic, 'aust' indicates a whole-of-Australia mosaic and the 'nc' suffix is for netCDF4 format data files. Files are written in netCDF4 format with compression.
