Project Status: active

Title: AMAX-DOAS trace gas column observations from the research aircraft over California

Contract Number: 09-317


Research Program Area: Atmospheric Processes

Topic Areas: Chemistry & Reactivity, Field Studies


Research Summary:

The proposed research is a key component of the CalNex 2010 field campaign planned by the Air Resources Board (ARB) and National Oceanic and Atmospheric Administration (NOAA), that will improve the understanding and characterization of sources and chemical processing of gaseous species and organic aerosols throughout California with emphasis on the South Coast Air Basin (SoCAB) and San Joaquin Valley (SJV). This proposed project is to deploy the University of Colorado Airborne Multi AXis DOAS instrument (CU AMAXDOAS) on the NOAA Optical Remote Sensing TwinOtter research aircraft during the eight-week CalNex period and following for an additional four weeks. The AMAXDOAS will measure pollutant concentrations in and above the boundary layer, probing directly the horizontal and vertical distributions of nitrogen dioxide (NO2), formaldehyde (HCHO), oxygen dimers (O4) and possibly glyoxal (CHOCHO) boundary layer columns over the SoCAB, SJV, and ocean. The measurement results will be used to test and constrain atmospheric models, validate satellite measurements, and provide improvements for models and validated satellite data for better management of air resources. The project will address aspects of emissions strength and atmospheric chemistry which are not only important scientifically but also of practical concern to the ARB for management of air quality.
