Due to NASA network policies the NASA Precipitation Processing System (PPS) will be transitioning from FTP to FTPS for access to download GPM and TRMM data. As a result of this change, users may need to update the methods they use to download data. Due to these changes users will no longer be able to access the PPS FTPS servers using a web browser, and will need to connect using either the command line or dedicated file transfer software. One piece of software that can be used to connect to the new FTPS servers is Filezilla, which is free and open source, and is available on Mac, Windows, and...
TMPA Shows El Niño Conditions in the Pacific
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. This map shows sea surface temperature (SST) anomalies for the Pacific Basin, shown as degrees Celsius above or below average. Credit: NOAA Climate Prediction Center. In a typical El Niño, warmer than average SSTs off of the...
Finding Strong Storms with TRMM & GPM
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. These precipitation features can then be mined to locate areas...

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). Specifically the PMM program supports three types of investigations: (1) The...

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: A typical presentation to this age group might look something like this: Everyone is sitting on the floor in a circle, and you are sitting on a small chair in front of them. Sometimes they sit on carpet squares or in...

Students in K-2nd grades are eager learners, and will love having a scientist come to visit their class! They can be a talkative bunch and often like to share their experiences and ideas. You might want to look over the suggestions in the document below to get a feel for Best Practices for giving presentations in Elementary Schools. There are many ways in which the science behind the GPM mission is meaningful and engaging to children in these grade levels. Here are some of the Next Generation Science Standards (followed by most states across the country) that relate directly to some themes you...

Students in 3rd through 5th grades are very interested in hearing about science from “real” scientists! They have begun to learn about natural phenomena all around them, but have many misconceptions as well. At this age, they will often have many questions and also want to share some of their understanding and experiences. Take a few minutes to read over the Best Practices for giving presentations in Elementary Schools to get a feel for what elementary school classes are like and some pointers for presenting to kids in these grade levels. There are many ways in which the science behind the GPM...

Students in middle school are very interested in hearing about science from “real” scientists! Although they have a lot of background knowledge about natural phenomena, they will also have misconceptions as well. They are also at the age in which they will begin to consider their future career interests, and hearing from you about why you chose your career will be very interesting to them. They may be reticent at first to answer questions for fear of “sticking out” among their peers. Take a few minutes to read over the “Giving Presentations in Secondary Schools” get a feel for what secondary...
