Himawari-8 was launched by JAXA (Japan Aerospace Exploration Agency) in 2015 and the Bureau of Meteorology has been producing the 10min full disk SST since mid-2017. With 10min sampling Himawari-8 greatly improves the chances of getting cloud-free images throughout the day but the 10min data also presents a data management issue. OceanCurrent provides images of 4hr composite SST based on the 2km Himawari-8 SST and all other AVHRR and VIIRS SST. Four-hour composites provide a high-enough time resolution SST record that allows small-scale oceanographic features to be discovered and followed, without overwhelming data volume. By including the higher resolution VIIRS and AVHRR SST we provide improved near-coastal SST. In particular, the VIIRS sensor offers the prospect of sub-1km spatial resolution which is an area of great potential and further research activity.
