Spring is severe storms season here in the US, but not everyone has NEXRAD radar coverage; however, NASA’s TRMM and GPM satellites with their onboard radars have made it possible to search the entire global Tropics and midlatitudes and systematically identify areas where there are strong to intense thunderstorms. Researchers now headed by Dr. Chuntao Liu at Texas A&M University have built a comprehensive database of “precipitation features” based on regions of contiguous radar echoes from first the TRMM and now the GPM satellite.
Content which is not specifically affiliated with GPM or TRMM, but which is about the Precipitation Measurement Missions in general.
An El Niño that began to form last fall has matured and is now fully entrenched across the Pacific. Changes in sea surface temperatures, or SSTs, brought about by an El Niño affect the atmosphere, resulting in distinctive changes in the rainfall pattern across the Pacific Basin. These changes show up as anomalies or deviations in NASA’s analysis of climatological rainfall.
The National Aeronautics and Space Administration (NASA), Science Mission Directorate, Earth Science Division has selected new projects from the 2018 Precipitation Measurement Missions (PMM) Science Team focus area solicitation. PMM projects focus on investigations related to satellite observations of precipitation using measurements from, but not limited to, the Global Precipitation Measurement (GPM) Core Observatory, GPM mission constellation partner spacecraft, and the Tropical Rainfall Measuring Mission (TRMM).
These are such fun little people with very short attention spans and lots of enthusiasm and questions! They will also want to tell you everything they know and then some, and everyone wants to get a turn to share in. While that is exciting, it can also sidetrack anything you are trying to convey pretty quickly!
Here are some general guidelines for working with this age group:
