The TRMM satellite had a very good view of tropical storm Flossie in the eastern Pacific Ocean on July 28, 2013 at 0734 UTC. The image on the left shows an analysis of rainfall data from that pass using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. TRMM PR data found rain falling at a rate of over 46 mm/hr (~1.8 inches) in storms just south of Flossie's center of circulation. TRMM PR also found that some of these storms were returning 45dBZ reflectivity values to the satellite indicating that moderate to heavy rain was falling in that area. The map on the right shows

The GPM Core satellite successfully completed vibration testing in July 2013, at NASA's Goddard Space Flight Center, Greenbelt, Md. The tests ensure that the spacecraft can withstand the vibrations caused by the Japan Aerospace Exploration Agency (JAXA) H-IIA rocket during satellite’s launch early in 2014. Sitting on a specialized mobile platform, the GPM spacecraft was abruptly moved back and forth in each of its three spatial orientations.

The TRMM satellite flew over tropical storm Dorian on July 24, 2013 at 1648 UTC providing data used in this image. Only light to moderate rainfall was found near Dorian's center of circulation by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. Precipitation is shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS).

Extreme, sometimes disastrous, monsoon rainfall has occurred so far over India during June and July 2013. The image above shows rainfall total estimates from space satellite data for the seven day period ending on June 17, 2013. Near real-time TRMM Merged HQ/Infrared Precipitation (3B42) data, with seven days totals, were analyzed for the period from June 14-July 25, 2013. These rainfall estimates are shown in simulated 3-D perspective views with higher precipitation amounts appearing to be taller than lower amounts. Rainfall totals were also color enhanced with lower amounts being assigned
