1  History of Sea Surface Temperature measurement  Current Satellites/ Instruments  Limitations  Applications  Remote Sensing - the next 10 years  By Stuart Milburn and Robyn Stevens

2 SRESAHRPT VHRRGEOMCSST AVHRR NOAAICOADS MODISNOPPNEMS SMMRNASASSM/I AMSRGODAE CrIMSSGHRSST-PP TRMM GHRSST- RANTMI FOAM REMSS MISST POES GOES

3 Long established record Reliable data since about 1870 Less data now than previously /docs/WMO-Pub47_jtech07-1.pdf

4 DRIFTER + Sampling usually taken at a known Depth e.g. SST-1m + Sub-surface sampling - Limited amount of data able to be collected. - Low resolution. Global Drifter Surface Buoy Array ~ 5’ Resolution Global Tropical Moored Buoy Network ARGO Floats

5  SR, VHRR on INSAT3-M  MODIS on TERRA, AQUA  ATSR on ERS-2  GOES Imager  AATSR on ENVISAT  AVHRR on NOAA series and ESA MetOP-A  Scan at IR wavelengths...  + Good Resolution (~1km)  + Accurate Results  + Long Dataset  - Obscured by Cloud NOAA

6  SMMR on Nimbus-7, SeaSat  TMI on TRMM  AMSR on EOS-PMI  CRIMSS  + Can see through cloud  - Not as accurate or as fine resolution as IR CRiMSS

7  SST measured at different levels  Skin Layer Diurnally heated  Evaporation  Radiometer Noise  Incidence angle  Radio Interference  Wind forcing alters SST measured NightDay

8  Archiving websites  Data available graphically  Near real time data  GHRSST: 6 hour delay  NOAA has data from 1981 to present, Oceanwatch  NASA provides data from MODIS since 2000  WASTAC (West Australian Satellite Technology and Applications Consortium)

9

10 Bureau of Meteorology uses the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA series of polar orbiting satellites to derive SSTs for the Australian region /oceancurrents/SNSW/latest.html

11  Meteorological Forecasting  Climate Models  ENSO Forecasting  Ocean Forecasting  Coral Bleaching  Fishing  Currents  Research and Development

12  New methods blending thermal IR and passive microwave satellite measurement and improvements with correlating these to in situ SST measurements (with QC)  Improved in situ SST “Ground Truth”  Better SST products through better algorithms/longer dataset/improved instruments  Scientific/International/Australian Collaborations – e.g. BMRC, CSIRO and Universities through ACCESS. Bluelink from BOM  New and improved Acronyms IOCI, SEACI, POAMA MDGSST, GHRSST-RAN, MISST, NPOESS, VIIRS, CrIMSS
