Coming Soon! This page will allow you to log into the PMM Science Team Portal to collaborate with your fellow scientists. Some of the features we are planning include: The ability to create personal profiles and view the profiles of your teammates. A wiki / forum for communication and sharing of ideas. A tool to schedule meetings with your fellow scientists. A tool for sharing documents and files. Check back here for updates on the status of this tool.

Freshwater seems abundant, but when accounting for all the water on Earth, it's in limited supply. Just three percent of the water on our planet is freshwater. A majority of this water, about two percent of the world total, is contained in glaciers and ice sheets or stored below ground. The remaining one percent is found in lakes, rivers and wetland areas or transported through the atmosphere in the form of water vapor, clouds and precipitation. Rain and snowfall replenish freshwater sources, making it vital to know when, where and how much water is falling at any given time. Using NASA's...

GPM is designed to advance scientific understanding of the Earth's water and energy cycle but also provides near real-time data for a wide array of societal applications. As a science mission with integrated application goals, the GPM mission has five scientific objectives: Advancing Precipitation Measurement from Space GPM advances precipitation measurement capability from space using a combination of active and passive remote-sensing techniques. These measurements are used to calibrate, unify and improve global precipitation measurements by a constellation of research and operational...
