A Quick Guide to NASA’s Newest Satellite

Global Precipitation Measurement (GPM) is a name worth remembering. First of all, it’s a satellite.  On February 27, 2014, GPM’s Core Observatory is scheduled to rocket into space from Japan’s Tanegashima Space Center carrying a radar and radiometer capable of measuring precipitation in new ways.

However, this joint NASA/JAXA mission is bigger than just one satellite. The scientists behind GPM are hoping that the core observatory will function like a key that “unlocks” and unifies data collected by a whole constellation of existing and future satellites.

GPM Constellation 1-13-14

 

For instance, an earlier precipitation-monitoring satellite called the Tropical Rainfall Measuring Mission (TRMM) also used radar to measure precipitation, but it could only detect moderate and heavy rain in tropical areas. GPM, in contrast, will also sense light rain and snow and will see nearly to the poles (65 degrees latitude north and south), meaning it will extend and improve upon TRMM’s measurements.

Expect to hear a lot more about this satellite over the next few weeks. There’s a lot of information to sift through if you want to learn more about the mission, but some of it can be tricky to find. To make the sifting a little easier, I’ve compiled a “best of guide” to images and other resources about the mission to make your search a little easier.  Stay tuned for more, follow the mission via @NASA_Rain and on Facebook, and enjoy the launch.

    Cumulo Nimbus clouds give us rain. Is it possible to locate this type of clouds from above, like we look at the sky from the earth surface? Spatial location and wind drift of this cumulo nimbus clouds determine the local weather pattern.

    Is it possible to quantify amount of moisture in a cumulo nimbus cloud? If possible we could forecast amount of rain receive for a particular micro catchment.

    Good Luck It will help a lot to understand earths rainfall.
