Earth Science: Observations of Trace Species in the Upper Troposphere and Lower Stratosphere Job at National Aeronautics and Space Administration (NASA)
National Aeronautics and Space Administration (NASA) Greenbelt, MD
“¢ What are the chemical fates of short-lived compounds transported from the tropical boundary layer into the Tropical Tropopause Layer (i.e., what is the chemical boundary condition for the stratosphere)?
“¢ What are the mechanisms that control ozone within the UT/LS?
“¢ What are the relative roles of large-scale transport and convective transport and how are these processes coupled?
“¢ How does urban pollution and biogenic emissions influence UT/LS photochemistry?
“¢ What is the impact of trace species, including volatile organics, on cirrus formation?
This research project addresses these questions through the in situ measurement of trace species such as formaldehyde (HCHO) from NASA high altitude aircraft (e.g., WB57, ER-2, and Global Hawk). The in situ measurements augment the capabilities of existing (AURA) and planned (e.g. GEO-CAPE, ACE) NASA satellites by providing high spatial and temporal resolution needed to test mechanisms that link the boundary layer with the global UT/LS and by providing validation with traceable laboratory calibrations.
