The rainfall measurements are from the Multisatellite Precipitation Analysis, which is based on data from the TropicalRainfallMeasuringMission (TRMM) satellite.
The MPA estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the TropicalRainfallMeasuringMission (TRMM) satellite.
In a recent study, researchers used computer models and data from NASA's TropicalrainfallMeasuringMission satellite to estimate how the dam's construction impacted area rainfall.
