15R2O GREMLIN use at the National Weather Service office in Pago Pago, American Samoa

The National Weather Service office in Pago Pago (American Samoa), WSO PPG, has an area of responsibility that surrounds several isolated islands in the tropical South Pacific Ocean. Traditional observations are scarce, and there is no radar coverage at this office. GREMLIN (GOES Radar Estimation via Machine Learning to Inform NWP) was developed at CIRA and has been flowing to the AWIPS machines in the office since summer of 2024, and this presentation will both describe GREMLIN and document various cases in which the simulated radar provided useful decision support for both light and heavy rain events in this tropical region.
