Ground data now being collected in northeastern Iowa by the Iowa Flood Studies (IFloodS) experiment will evaluate how well NASA's Global Precipitation Measurement mission satellite rainfall data can be used for flood forecasting. With rainfall estimates in hand, the science teams input them into flood prediction computer models and then evaluate how the rain estimates and their uncertainties affect the outcome of the flood forecast.
The Global Precipitation Measurement, or GPM, mission will set a new standard for precipitation measurements from space and it's doing so by joining forces with countries around the world, keeping not just one satellite's weather eye on the horizon, but nine.
The short video "For Good Measure" explains why scientists turn to satellites to get a worldwide view of rainfall. Filmed at NASA's Goddard Space Flight Center in Greenbelt, Md., with a cast of more than 20 volunteers, the video walks through how rain touches our lives and how scientists plan to improve measurements with the upcoming Global Precipitation Measurement mission.
Join 60 of NASA's social media followers on Friday, April 12 at NASA's Goddard Space Flight Center in Greenbelt, Md., to learn about the many missions and partnerships between NASA and the Japan Aerospace Exploration Agency (JAXA). Held on the Friday before a weekend of events at the National Cherry Blossom Festival in Washington, D.C., the day-long NASA Goddard event is designed to be a celebration of the many successful and ongoing missions between NASA and JAXA.
The Global Precipitation Measurement mission is happy to announce the top ten winners of the "Let It Snow" photo competition. Thank you to everyone who submitted their best pictures of winter. From January 7th through February 4th 2013, over 1,000 photos were submitted via Flickr and Instagram (see the Flickr submissions here). We loved all of your entries and thoroughly appreciate your participation.
NASA and the Community, Collaborative Rain, Hail, and Snow Network (CoCoRaHS) run by Colorado State University, Fort Collins, invite the public to participate in a free webinar on February 13th 2013 to promote citizen science that involves rain and snow measurements across the United States. CoCoRaHS is a citizen scientist network with more than 16,000 volunteers nationwide that encourages volunteers of all ages to record and monitor precipitation using accurate, low-cost rain gauges.
GPM is proud to announce the follow-up to our popular Extreme Weather Photo Contest! Winter winds blow in cold air, snow, ice, freezing rain, and a slew of other cold weather phenomena. What is winter like in your area or favorite vacation spot? Post your coolest photos of winter weather and we'll pick the best ones to feature on the NASA Precipitation Measurement Missions websites! UPDATE: Submissions accepted from 1/7/13 -> 2/4/13
Weather forecasts have come a long way, but almost every season there's a snowstorm that seems to come out of nowhere, or one that's forecast as 'the big one' that turns out to be a total bust. In the last ten years, scientists have shown that it is possible to detect falling snow and measure surface snowpack information from the vantage point of space. But there remains much that is unknown about the fluffy white stuff.
