Benefits of dealing with climate change and air quality togetherBenefits 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).
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
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.

NOAA’s Science Issues
• Emissions Quantification - Greenhouse Gases and O3 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 (2002-2008-2010)

vAddressing CalNex science questions
http://esrl.noaa.gov/csd/calnex/scienceplan.pdf
• 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.
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 - 2006
In 2010, Joint flights with P-3, Twin Otter, and NASA King Air will be useful
http://esrl.noaa.gov/csd/calnex/scienceplan.pdf
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
