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
