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

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 California East Texas 2000, 2006 Southeast 1994, 1995, 1999 New England 1993, 2002, 2004 ITCT 2002 CCOS 2000 West 1996 Chemically and Meteorologically Diverse

IPCC 2007 AR4 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 CO 2. Can give quick payoffs for climate (years instead of many decades). -These agents all have common sources (transportation, industry, agriculture, forests). NOAA’s Climate and Air Quality Regional Intensives NOAA’s Climate and Air Quality Regional Intensives CalNex 2010 = Our first steps at integrating these 2 issues

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. 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.

NOAA’s Science Issues Emissions Quantification - Greenhouse Gases and O 3 and Aerosol Precursors – improved emission inventories, particular focus on GHG, soot and sulfur emissions.

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 ( ) Addressing CalNex science questions

Chemical Transformation - O 3 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. NOAA’s Science Issues (cont.)

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

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
