NASA's Tropical Rainfall Measuring Mission (TRMM) and Aqua
satellites are just two in NASA's fleet that have been providing
data on the evolving and now devolving tropical cyclone. TRMM
provided rainfall and other data, while the AIRS instrument on
NASA's Aqua satellite provided cloud temperature and extent.
Typhoon Mawar was weakening when the TRMM satellite saw it
during the daytime on June 5, 2012 at 0728 UTC (3:28 a.m.
EDT/U.S.). Rainfall derived from TRMM's Microwave Imager (TMI)
and Precipitation Radar (PR) instruments showed that Mawar was
producing a very large area of rainfall southeast of Japan. Most
of Mawar's heavy rainfall is revealed by TRMM to be north of the
dissipating tropical cyclone's center. The most intense surface
rainfall of over 40mm/hr (~1.6 inches) was shown northeast of
the center. Much of Mawar's southwestern side was shown becoming
rain free. A 3-D image from TRMM's PR shows that Mawar no longer
had an eye wall. Storms near Mawar's center of circulation were
reaching to heights o
