Too much or too little rainfall can have significant impacts on populations around the world. As population and global temperatures increase, it is crucial to understand what locations will become more vulnerable to extreme rainfall and drought and the subsequent natural hazards (e.g., landslides) and risks (e.g., lose of property) they impose. Satellites allow us to monitor changes in the precipitation, especially over oceans and regions where ground-based data are sparse. With its near-real-time precipitation estimates and near global coverage, GPM serves as an essential tool for assessing

Precipitation extremes, from heavy rainfall to droughts, pose great risks to a country’s economic development and human health. Standing water and flooding resulting from heavy rainfall has created societal vulnerabilities to vector and waterborne disease outbreaks such as malaria, schistosomiasis, cholera, and chikungunya, among others. Drought and extreme heat conditions have been associated with a wide range of health hazards including degraded air and water quality. These meteorological extremes also impact the growth of cities such as damaging transportation networks and infrastructures
