<Nov. 29, 2023>
GCOM-W/AMSR2 SST data distribution via the JAXA GHRSST server was already back to normal status.
We apologize for the inconvenience.

<Nov. 27, 2023>
The provision of new products have been delayed due to the system maintenance perform on today.
We apologize for the inconvenience.

<Nov. 08, 2023>
Due to unavailability of reference data used in GMI SST retrievals, we have suspended distribution of the GMI SST product since 16 February 2023. In addition, we extended data suspension due to orbit boost of the GPM Core Observatory in Nov. 2023.
We will restart distribution of it after tuning of retrieval algorithm to new reference data and checked data after the orbit boost.


JAXA provides near-real-time data Sea Surface Temperature (SST) retrievals from several passive microwave imagers as a contribution to the Group for High Resolution SST (GHRSST).
Those SST products are produced at Earth Observation Research Center (EORC) of Japan Aerospace Exploration Agency (JAXA).
All SST products are in GDS format defined by GHRSST, and available as L2P (swath grid) and L3C (daily grid) products.
