Title: Synthesis of policy relevant findings from the Calnex 2010 field study

Principal Investigator / Author(s): Parrish, David and Joost de Gouw

Contractor: National Oceanic & Atmopsheric Administration (NOAA)

Contract Number: 10-326

Research Program Area: Atmospheric Processes

Topic Areas: Field Studies


The CalNex 2010 field study was jointly organized and conducted by the California Air Resources Board (CARB) and the National Oceanic and Atmospheric Administration (NOAA) in the late spring and early summer of 2010, with the goal of investigating scientific issues at the nexus between air quality and climate change. This report is intended to ensure that the results of the analysis of the field observations are made available to California policy makers in a timely fashion. The findings from the CalNex research are here synthesized in a form most useful for those who must deal with air quality and climate change issues. The goal is to provide a comprehensive and integrated presentation of our current understanding of these interrelated issues in California. This Synthesis is organized around 23 policy-relevant Science Questions formulated by CARB in consultation with NOAA. Findings in response to each of these questions address six general areas:
1) Meteorology during the CalNex field study period and atmospheric climatology,
2) An assessment of emission inventories of air pollutants and climate forcing agents, including greenhouse gases,
3) An assessment of climate processes and atmospheric transformations,
4) An overview of important atmospheric transport processes,
5) An assessment of the skill of current air quality modeling and forecasting systems, and
6) A discussion of the areas where it is particularly important to simultaneously consider the air quality and climate impacts of policy decisions.
