The PO.DAAC is issuing a data outage alert on the GHRSST Level 4 G1SST Global Foundation Sea Surface Temperature Analysis ( dataset. From 9 December 2019 to present, the G1SST dataset has produced poor quality SST results. This matter is currently being investigated, but due to current lack of support (funding and resources), we do not anticipate a quick resolution to the situation. To prevent any further confusion in the user community, PO.DAAC has decided to remove all the bad granules and temporarily stop ingesting the G1SST data from 9 December 2019. We apologize for any inconvenience. To minimize further disruption to existing G1SST data users, the PO.DAAC advises users to consider using the GHRSST Level 4 MUR Global Foundation Sea Surface Temperature Analysis v4.1 (, which provides comparable data at the same spatial sampling and coverage as G1SST.
