[ACG36-03] Recent Developments and Plans in the U.S. GPM Project
Keywords:GPM, IMERG, satellite precipitation, global rain and snowfall
The use of GPM data will be illustrated, with examples drawn from the eventful Atlantic hurricane season of 2017. These range from scientific studies using GPM-CO sensor data, to the use of IMERG in Puerto Rico following Hurricane Maria, when ground-based radar systems on the island were destroyed. IMERG also contributes to a better understanding of rainfall accumulation, inland flooding, and landslide susceptibility during the passage of hurricanes and other prolific rainfall events.
Future plans will be reviewed, including research into the challenging problem of accurate snowfall retrievals, extension of multi-satellite precipitation estimates to fully global coverage, and the use of numerical model-based precipitation estimates to complement observational retrievals. Finally, one key issue for the future is ensuring the on-going constellation of passive microwave satellites.
