Tropospheric Chemistry

Affiliation

CIRES

Dr. Neuman is a research scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) and an affiliate with the NOAA Earth System Research Lab. He joined the lab in 1997, studying the upper troposphere and lower stratosphere using instruments developed for high altitude aircraft. Since 2000, his research has concentrated on atmospheric chemistry and transport in the lower troposphere. Chemical ionization mass spectrometers have been developed and operated to measure trace gases from the NOAA WP-3D aircraft. Data from these instruments are used to examine long-range transport of pollutants, aerosol formation, photochemical ozone production, and arctic ozone depletion.
