Sea Surface Temperature Monthly Means and Variance in the Australian Region
공공데이터포털
The CSIRO Marine Research Remote Sensing facility automatically receives and archives data from the USA's National Oceanographic and Atmospheric Administration (NOAA) satellites. Up to 18 passes per day are tracked to receive data. The Advanced Very High Resolution Radiometer (AVHRR) data is received on the High Resolution Picture Transmission (HRPT) signal. Within an hour of reception, these data are automatically processed into full resolution sea surface temperature (SST) images. Raw data originate from the AVHRR sensor on various NOAA polar orbiting satellites, received at various stations around Australia and consolidated ("stitched") by the CSIRO Earth Observation Centre. The stitching removes redundancy and minimises data corruption. Processing from the stitched archive to produce SST is carried out in the CMAR Remote Sensing Facility in Hobart using the split window algorithm of McMillin for NOAA9 and NOAA12 satellites and the NLSST (NOAA non-linear SST) algorithm for the other satellites. Cloud-clearing is performed based on the algorithm of Saunders and Kriebel. Each map is made by combining the estimates over the composite period using a time and spatial neighbourhood median filtering method. Each pixel of the images is the 65 percentile of all cloud-cleared SST estimates during the composite period and within a 4x4 km region. The compositing process also removes most residual cloud contamination. This basedata has been produced by CSIRO for the National Oceans Office, for the purposes of marine mapping, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project. Compositing attempts to overcome the problem of cloud coverage. The compositing technique used here takes the median value of a 4 by 4 neighbourhood of 1km resolution pixels over all the data available for that time period. If there has not been at least one cloud free view of a point on the ground during the composite period, the value recorded may show a false low temperature.
Tasmanian region daily sea surface temperature from observations and CMIP6 models
공공데이터포털
Data was collected and processed for the project: "Assessment and communication of risks to Tasmanian aquaculture and fisheries from marine heatwaves". Observational data is from NOAA OISST v2.1 (1982-2020), and model data is from 25 CMIP6 models over the historical period (from 1982-2014), with SSP1-2.6 and SSP5-8.5 extensions (out to 2100). Raw sea surface temperature data truncated to the Tasmanian region: 138-155E, 49-35S. Time-series of subdomain area averages are also provided, along with calendar corrections, mean-bias corrections, and seasonal bias corrections for the model data.

Sea Surface Temperature (SST) Data from GRNS-funded Study, 1995-1996
공공데이터포털
Sea surface temperature data (daily and weekly composites) from NOAA Advanced Very High Resolution Radiometer (AVHRR) data received at the Hobart station and processed at CSIRO Marine Research Remote Sensing Facility. The images cover an area from 21.3 to 50.0 degrees South, 130.3 to 167.0 East. The images correspond to the regions and time periods of Southern Surveyor research voyages SS 01/95, SS 11/95, SS 05/96 and SS 11/96, in south-eastern and east Australian waters. The data are contained on CDROM in Hobart, and copies are sent to GRNS (and others?). The Global Research Network System (GRNS) project was carried out between 1993-1997 sponsored by the Japanese Science and Technology Agency (STA).
NOAA AVHRR sea surface temperature images for the Australasian region - (multi-groundstation, multi-pass, composite images)
공공데이터포털
Sea surface temperature data, in 1, 3, 6, 10 and 15 day composite periods, at approximately 4 km resolution processed from NOAA Advanced Very High Resolution Radiometer (AVHRR) data received at Australian Stations and transformed to the stitched archive (see related record). Temporal coverage of the data is from October 1993-June 2003 and will be extended backwards and forwards through time. The data are in netCDF files and can be viewed as graphics or downloaded as data files from http://www.marine.csiro.au/remotesensing/oceancurrents/
