Abstract:
The Tropospheric Chemistry Program at the National Aeronautics and Space Administration (NASA) has recently conducted a number of airborne science missions over North America and adjacent oceans to understand the impact of long-range transport of trace gases and aerosols on the changing chemical composition of the troposphere. Regional-scale measurements were made over the eastern United States (INTEX-NA summer 2004); Mexico (MILAGRO March 2006); the North Pacific and Alaska (INTEX-B May 2006); the Canadian Arctic (ARCTAS spring and summer 2008); and California (CARB June 2008). For these field campaigns, instrumentation for the in situ measurement of CO2 was integrated on the NASA DC-8 research aircraft providing high-resolution (1 second) data traceable to the global calibration scale. These observations provide unique and definitive data sets via their intermediate-scale coverage, and frequent vertical profiles throughout the troposphere (0.1 – 12 km) for use in inversion and other global modeling studies.
