1. CalNex 2010: The NOAA Perspective DAVID PARRISH Chemical Sciences Division Earth System Research Lab Boulder, Colorado CARB Board Meeting San Diego, 23 July 2009 http://esrl.noaa.gov/csd/calnex/scienceplan.pdf

2. CalNex 2010: The NOAA Perspective • Today: • Address both Climate and Air Quality • Science Issues • NOAA’s Contributions to CalNex CARB Board Meeting San Diego, 23 July 2009 http://esrl.noaa.gov/csd/calnex/scienceplan.pdf

3. NOAA’s Climate and Air Quality Regional Intensives CalNex 2010 will be our first effort in California with full capabilities, and with a major air quality focus ITCT 2002 New England 1993, 2002, 2004 West 1996 CCOS 2000 California Southeast 1994, 1995, 1999 East Texas 2000,2006 Chemically and Meteorologically Diverse

4. NOAA’s Climate and Air Quality Regional Intensives CalNex 2010 = Our first steps at integrating these 2 issues Benefits of dealing with climate change and air quality together • • Climate change and air quality are highly interrelated. • The major air pollutants—aerosols (including soot) and ozone—are also significant climate change forcing agents. • These “common agents” are short-lived (days to months), compared to centuries for CO2. Can give quick payoffs for climate (years instead of many decades). • These agents all have common sources (transportation, industry, agriculture, forests). IPCC 2007 AR4

5. CalNex: A first step for the Nation toward providing information for integrated regional decision-making on air quality and climate Why California? • California’s leadership on these issues and its diversity of emissions make it an ideal testbed. • Science information needed to support California’s efforts at integrated climate and air quality management. • California already has considerable efforts and capabilities that CalNex can leverage to benefit the Nation • Payoffs from CalNex • Science-based options for air quality and climate decision-makers in California. • Information that can be extended to other regions of the Nation.

6. NOAA’s Science Issues • Emissions Quantification-Greenhouse Gases and O3 and Aerosol Precursors – improved emission inventories, particular focus on GHG, soot and sulfur emissions. http://esrl.noaa.gov/csd/calnex/scienceplan.pdf

7. Addressing CalNex science questions • Emissions Quantification - • Example: Sulfur budget of LA Basin • Research vessel will sample ship emissions (ports, offshore) • WP-3D aircraft can sample urban areas and point sources throughout California • Track changes (2002-2008-2010)

8. NOAA’s Science Issues (cont.) • Chemical Transformation- O3 and Aerosols, Day and Night, Gas-Phase and Heterogeneous – improved chemical mechanisms for air quality modeling, particular focus on organic and sulfate formation. • Transport and Mixing- Intercontinental, Inter- and Intra-state, Boundary Layer/Free Troposphere – improved understanding of how we are affected, and affect, our neighbors. http://esrl.noaa.gov/csd/calnex/scienceplan.pdf

9. Addressing CalNex science questions Transport and Mixing- Use chemical measurements to define pathways for export of LA Basin and Central Valley pollution NOAA Twin Otter airborne lidar data - Houston - 2006 In 2010, Joint flights with P-3, Twin Otter, and NASA King Air will be useful

10. NOAA’s Science Issues (cont.) • Aerosol Properties and Radiative Effects- Regional Haze, Direct Radiative Forcing, Cloud-Aerosol Interactions, Satellite Validation – Reduced uncertainty in the role of aerosols in climate – Improved understanding of role black carbon plays in climate • Model Development- Diagnostic Evaluation of Forecast Models, Chemical Data Assimilation, Regional Climate Models http://esrl.noaa.gov/csd/calnex/scienceplan.pdf
