NOAA AVHRR sea surface temperature images for the Australasian region - (multi-groundstation, multi-pass, composite images)
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/

Variable: depends on cloud density and prevalence of other atmospheric interference. Values are calibrated as bulk temperatures but no adjustments for diurnal cycling of near-surface stratification, etc, are made. Nominally +/- 1 degree Celcius.

- Statement
-
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 CMR 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 map is the 65 percentile of all cloud-cleared SST estimates during the composite period and within a 4*4 km region. The compositing process also removes most residual cloud contamination.
