R/V Atlantis Support of NOAA CalNEX 2010 Cruise This NOAA study is a collaboration between NOAA, the California Air Resources Board, and the California Energy Commission. NOAA and its California partners are planning a combined regional air quality and climate study within California and the eastern Pacific coastal region. This field campaign will target the formation of pollution within California urban, industrial, and agricultural regions; transport of the pollution offshore; and the resulting impacts on regional air quality and climate. NOAA will use a UNOLS vessel in combination with ground sites and airborne platforms to determine how the transport and transformation of gaseous and aerosol chemical species influence air quality and climate forcing. These observations will be paired with diagnostic chemical, meteorological, and radiative models to assess and improve the forecasting and prediction tools.
