The Precipitation and All-Weather Temperature and Humidity Mission would be designed to observe and improve understanding and modeling of hurricanes, severe weather and related hydrology-cycle processes:
- N. Atlantic hurricanes
- CONUS severe storms
- E. Pacific hurricanes
- Tropical moisture transport
- Oceanic and continental atmospheric processes
- Diurnal cycles
As defined by the NRC Decadal Survey, PATH is currently a third-tier mission, set for a possible launch sometime between 2016 and 2020. It will be a medium size mission and carry an microwave array spectrometer (GeoSTAR is a possible candidate for this).
