Jessica Neu

Dr. Jessica Neu's research focuses on understanding what controls the chemical composition of the atmosphere at the regional and global scale and, ultimately, how atmospheric composition will change with and feed-back onto changes in other components of the climate system. She employs a hierarchy of models of varying complexity in combination with measurements from both satellite remote sensing and in situ instruments, and her work encompasses a wide variety of techniques, including theoretical studies, numerical modeling, and analysis of observational data to address these issues. Her work has recently evolved to include data assimilation and adjoint modeling techniques to facilitate model-measurement intercomparison as well as Observing System Simulation Experiments to define science objective-based requirements for future satellite missions.


Education
  • B. S., Meteorology, Texas A&M University (1991-1995)
  • Ph.D., Atmospheric Sciences, Massachusetts Institute of Technology (1995-2001)

Research Interests
  • Processes controling the abundance of O3 in the troposphere, at scales ranging from plumes to clouds to weather systems to the global circulation.
  • Coupling and feedbacks between air quality and climate through radiation, temperature, and transport.
  • Importance of the stratosphere in tropospheric climate and composition, including the role of stratospheric ozone in the tropospheric ozone budget, both directly through stratosphere-troposphere exchange and indirectly through the radiation budget
  • Development of integrated analysis strategies for using measurements to test and improve models
  • Applications of multi-spectral satellite measurements for air quality studies.

The Microwave Limb Sounder (MLS) experiments measure naturally-occurring microwave thermal emission from the limb (edge) of Earth's atmosphere to remotely sense vertical profiles of atmospheric gases, temperature, pressure, and cloud ice.

TES Icon TES
TES (Tropospheric Emission Spectrometer) is one of four science instruments aboard NASA's Aura satellite, which was launched from Vandenberg Air Force Base, California on July 15, 2004.
