Professor of Earth System Science [Ph.D, in Oceanography from Rosenstiel School of Marine and Atmospheric Science, University of Miami, FL]. Professor Saltzman brings expertise in detection of atmospheric trace gases, and of fluxes and cycling of trace gases through the marine atmosphere.

Dr. Saltzman’s research is focused on understanding the atmospheric cycling of low- level biogenic trace gases which have the potential to strongly impact the climate system. Examples of such gases include dimethylsufide, which influences cloud radiative properties, and the methyl halides, which influence stratospheric ozone.

One current activity is a study of the role of reactive halogens in tropospheric photochemistry. This effort involves the development of atmospheric pressure, chemical ionization mass spectrometric (APCI-MS) methods for low level detection of reactive halogenated gases, such as Br2, Cl2, HOBr, HOCl, Field studies involve measurements both at remote marine sites and in coastal polluted air. The goal of this research is to understand the how reactive halogens cycle between gas and aerosol phases and to assess the impact of halogen chemistry on tropospheric reactivity and air quality.

Another research activity involves the direct measurement of air/sea fluxes using micro-meteorological techniques. This involves seagoing deployment of APCI-MS instrumentation and real-time, fast response measurements of dimethylsulfide in air and seawater. The goal of this work is to quantify the air/sea transfer of dimethylsulfide and to develop physically-based models of gas transport across the air/sea interface.

The Saltzman laboratory is also engaged in the extraction and analysis of trace gases from polar ice cores. This work is focused on trace halocarbon, hydrocarbon, and sulfur-containing gases and it involves the use of high resolution mass spectrometry with isotope dilution. The goals of this work are to explore the range of natural variability of the trace gas composition of the atmosphere, to understand the role of climate in atmospheric variability, and to assess the impact of industrialization on atmospheric chemistry. This work involves the collection and analysis of firn air and ice cores from Greenland and Antarctica.

Prior to joining UCI in 2000, Dr. Saltzman was Professor of Marine and Atmospheric Chemistry at the University of Miami and Program Manager for Atmospheric Chemistry at NSF.
