Paul O. Wennberg

Paul O. Wennberg is the R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering at the California Institute of Technology. His research focuses on atmospheric photochemistry, the terrestrial carbon cycle, and oxidative chemistry of trace gases, with applications in climate modeling and satellite validation.

His group developed the Total Carbon Column Observing Network (TCCON) for global greenhouse gas monitoring and collaborates with NASA's Orbiting Carbon Observatory program. Research themes include coupling radiation, climate, and chemistry in the troposphere, anthropogenic impacts on atmospheric composition, and novel mass spectrometry methods for airborne/satellite data.

Recent publications emphasize atmospheric oxidation processes (e.g., peroxy radical isomerization), urban air quality (e.g., Seoul and Southern California), satellite validation (e.g., MOPITT and OCO-2), and tropospheric methane dynamics. Key trends involve isoprene chemistry, NOx cycling, and aerosol formation mechanisms.

Scientific Awards:

• R. Stanton Avery Professorship

He contributes to NASA missions and international networks like TCCON, with expertise in chemical ionization mass spectrometry and reactive trace gas analysis. His lab integrates field measurements, laboratory experiments, and satellite observations to study global atmospheric change.
