NASA announced today that the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) project has been selected as one of five Earth Venture Suborbital science campaigns that will begin in 2019. DCOTSS, led by Kenneth Bowman of the Department of Atmospheric Sciences at Texas A&M University, will investigate how strong convective storms over the U.S. affect the summertime stratosphere.

The project will use the NASA ER-2 high-altitude research aircraft, in combination with groundbased meteorological radars and NASA and NOAA earth observing satellites, to study the interaction between intense convective storms, These storms regularly penetrate deep into the lower stratosphere, carrying pollutants that can change the chemical composition of this atmospheric layer, potentially including stratospheric ozone.

Participating universities and government organizations include Texas A&M University, Harvard University, Massachusetts Institute of Technology, NASA Ames Research Center, NASA Armstrong Flight Research Center, NASA Goddard Space Flight Center, NASA Langley Research Center, the National Center for Atmospheric Research, the National Oceanic and Atmospheric Administration, Texas A&M University Corpus Christi, the University of Miami, the University of North Dakota, and the University of Oklahoma.

Research flights by the ER-2 aircraft will take place during the summers of 2020 and 2021 from Salina, Kansas.
