The Advanced Baseline Imager (ABI) rainfall rate algorithm generates the baseline rainfall rate product from ABI infrared brightness temperatures and is calibrated in real time against microwave-derived rain rates to enhance accuracy. The algorithm generates estimates of the instantaneous rainfall rate at each ABI IR pixel. The information provided by the quantitative precipitation estimation is used by forecasters and hydrologists in flood forecasting.
