NASA's Eyes on Rainstorms, Hurricanes, and Floods

By: Dr. Marshall Shepherd , 5:10PM,GMT on April 30,2015





Sunday's WxGeeks is really special for me because it is rooted in my professional legacy. Often, viewers are curious about my professional background as a meteorologist. They may know that I am a Professor at the University of Georgia or that I was 2013 President of the American Meteorological Society. But many WxGeeks viewers may not realize that I spent 12 years of my career as a Research Meteorologist at NASA's Goddard Space Flight Center. During that time, I developed a vigorous research program involving precipitation variability and extremes. I have published over 75 peer-reviewed papers on aspects of urban rainfall, flooding, tropical storms, and convective storms. I also served as Deputy Project Scientist for NASA's Global Precipitation Measurement (GPM) Mission. GPM launched last year and my good friend Dr. Gail Jackson is its Project Scientist (Link). By the way, if you haven't see the new global precipitation maps coming from the mission, take 5 seconds and click this link. It is worth it (Link).

The forerunning to GPM was the Tropical Rainfall Measuring Mission (TRMM). Both TRMM and GPM are a part of NASA's Earth Science Program (Link). Wait, doesn't NASA launch space shuttles or send rovers to Mars? Why are we wasting money studying Earth? Ummmmmmmmmmmm, because as important as learning about other planets are, we better understand this one first. We won't be visiting our "vacation planet" any time soon. You can learn about NASA's Earth Sciences program here (Link).

TRMM and GPM have advanced our knowledge of weather, climate, and hydrologic processes in so many ways scientifically. However, you may be surprised to learn that NOAA, USAID, USGS, and private stakeholders utilize the satellite data in operational or societal applications too. However, from a "geek" factor, I just think that it is cool that we figured out how to measure rainfall or snowfall from space using radars and other microwave instruments. How is that done? We'll tell you Sunday on WxGeeks.

I have invited 2 NASA colleagues, Dr. Scott Braun (TRMM Project Scientist) and Dr. Jeff Halverson (former TRMM Outreach Scientist and Professor at University of Maryland Baltimore County), to share the legacy of TRMM and the promise of GPM. We also get into a discussion of how these missions are improving weather forecasting, climate diagnosis, hurricane prediction, and more. Scott and Jeff have also been involved in some really cool field experiments using the Global Hawk UAV and other geeky technology to improve our understanding of hurricanes (Link) or (Link). I will ask them about this work and why hurricane intensity forecasts have lagged track forecasts in improvements. And as usual, NASA has provided us with some amazing visuals that you will not want to miss. Oh, I should mention that many WxGeeks viewers may recognize Dr. Halverson from his writings in Weatherwise and Capital Weather Gang (Link), respectively.

We can't wait to bring you this episode Sunday.

We have some really great shows lined up for the next couple of weeks including a look at the role of analytics in weather. It will be great to have Paul Walsh, Paul Walsh, Vice President, Weather Strategy / The Weather Company and Glen Finch , Global Leader of Big Data & Analytics / IBM join us. Also, we have a great show with Denver Broncos Tight End Owen Daniels, a degreed meteorologist and NFL football player. This show may have some other surprises too.

Please join us Sunday at Noon ET (11 CT, 10 MT, 9 PT).
