"Count Storms from Space - A
Perspective from NASA Precipitation Measurement Mission"
From December 1997 to April 2015, the Tropical Rainfall
Measuring Mission (TRMM) satellite has collected more than one
hundred million snapshots of various precipitation systems, or
so-called precipitation features, in tropics and subtropics.
Using these precipitation features, the properties of different
types of precipitation systems and their roles in the global
water and latent heat budget in the tropics and subtropics have
been studied extensively. Since the launch in February 2014, the
Global Precipitation Mission (GPM) core satellite, the successor
of TRMM, has provided more than four-year space borne
precipitation radar observations covering more than 90% of the
Earth. With a similar approach, twenty-three million
precipitation features have been defined by grouping the
contiguous precipitation areas indicated by precipitation radar.
This presentation briefly reviews what we have learned from more
than 17-year TRMM observations during the past decades, and
introduces exciting findings from the new GPM observations. The
topics include seasonal, diurnal variations of global
precipitation, deep convection, latent heating, as well as
severe weather monitoring with GPM constellation satellites.
About the Speaker:
Dr. Chuntao Liu is an Associate Professor of Atmospheric
Sciences in the Department of Physical and Environmental
Sciences and has been employed at Texas A&M
University-Corpus Christi since 2013. His primary research
interests are in the areas of satellite remote sensing of global
precipitation, cloud, and severe weather events, with an
emphasis on the cloud object recognition in space borne radar
and radiometer observations. Chuntao completed his Ph.D. in
atmospheric sciences at the University of Wyoming in 2003, where
he also stationed at McMurDo, Antarctic monitoring the
stratospheric ozone with balloons for two seasons. Then he
joined University of Utah working on the global precipitation
and severe weather events using NASA satellites. Currently
Chuntao maintains an instrument measuring the fair-weather
electric field at Barrow, Alaska, and is a science team member
of NASA precipitation science mission.
