About JAXA Himawari Monitor: Ocean Weather Forecast

JAXA has developed the system of "Ocean Weather Forecast" around Japan under collaboration with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

The system produces the analysis and forecast data using data assimilation technique which integrates JAXA's satellite-based sea surface temperature retrieved by Himawari-8, AMSR2, etc. and outputs of high-resolution regional ocean model (JCOPE-T) developed by JAMSTEC.

We provide recent 7-day analysis and future 10-day forecast data with daily updates.

The output sea surface temperature by the Ocean Weather Forecast can be downloaded afteruser registration at the P-Tree web site.

Two satellite SST products (GCOM-C/SGLI and NPP/VIIRS) have been added as inputs to the assimilation system since Nov. 14, 2019.
