Starting 24th March 2016, the Australian Bureau of Meteorology (BoM) has produced operational, real-time, sea surface temperatures (SST) from the Himawari-8 geostationary satellite every 10 minutes at ~2 km spatial resolution (at nadir) on the native satellite ("GEOS") projection.  For ease of use, and to reduce spatial data gaps due to cloud, these native resolution SST data have been composited to hourly and daily mean SST files, projected onto a rectangular Integrated Marine Observing System (IMOS) grid at 0.02 x 0.02 degrees.  The compositing of the Himawari-8 data on the IMOS grid presents opportunities for use alongside the IMOS 2 km "Multi-Sensor" SST products, incorporating data from the Visible Infrared Imaging Radiometer Suite (VIIRS) and Advanced Very High-Resolution Radiometer (AVHRR) satellite sensors, to identify coastal upwelling events.  The new IMOS Himawari-8 and Multi-Sensor satellite SST products will be described, and it will be demonstrated that they can be used to verify the efficacy of the BoM operational ocean forecasting system (OceanMAPS) 10 km resolution model (BoM, 2017) in resolving and predicting coastal upwelling around the Australian coast.
