Statement: The radiometric sensitivity of the MODIS 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 updated on 1 September 2020 to use processing in SeaDAS v7.5 and between 2002/07/04 and 2022/06/30 are consistent with the R2018.0 reprocessing (https://oceancolor.gsfc.nasa.gov/reprocessing/r2018/aqua/). Data between 2022/07/01-2023/01/31 and then from 2023/02/01 onwards, have been processed with two more recent releases of SeaDAS and are yet to be fully verified for consistency with NASA’s most recent processing(s). Once consistency has been established, the entire data set (from 2002/07/04) will be updated and this metadata record will be changed to reflect that. 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 A.P1D.<yyyymmdd>T<hhmmss>Z.<region>. .nc, where 'A" denotes the Aqua/MODIS sensor, 'P1D' is a period of 1 day, '<yyyymmdd>T<hhmmss>Z' is the UTC date+time of the centre of the compositing interval, '<region>' is the area covered (normally 'aust' for Australasia). ' ' is the name of the data ...
