| Summary: | Credit Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. Credit Bureau of Meteorology (BOM) Credit CSIRO Oceans & Atmosphere As part of the Integrated Marine Observing System (IMOS), the Australian Bureau of Meteorology produce high-resolution satellite sea surface temperature (SST) products over the Australian region, designed to suit a range of operational and research applications. All these products follow the latest International Group for High Resolution Sea Surface Temperature (GHRSST: www.ghrsst.org) file formats, assisting international data exchange and collaboration. The highest spatial resolution (1 km x 1 km) data from Advanced Very High Resolution Radiometer (AVHRR) sensors on NOAA polar-orbiting satellites can only be obtained through receiving direct broadcast “HRPT” data from the satellite. In Australia, HRPT data is received by a number of agencies (Bureau of Meteorology, Geoscience Australia, AIMS and CSIRO) and consortia (WASTAC and TERSS) at ground-stations located in Darwin, Townsville, Melbourne, Hobart, Perth and Alice Springs and in Antarctica at Casey and Davis Stations. The Bureau of Meteorology, in collaboration with CSIRO Marine and Atmospheric Research, is combining raw data from the various ground-stations and producing real-time HRPT AVHRR skin (~ 10 micron depth) SST data files in the GHRSST GDS v2.0 L2P (single swath, geolocated), L3U (single swath, gridded), one and three day daytime/night-time L3C (single sensor, multiple swath, gridded) and one, three and six day daytime/night-time L3S (multiple sensors, multiple swath, gridded) formats. The L2P, L3U, L3C and L3S files for NOAA-15, 17, 18 and 19 satellite data are available through the IMOS FTP server (ftp://aodaac2-cbr.act.csiro.au/imos/GHRSST), IMOS AO-DAAC ...
