Focus

The primary focus of our research group is to provide integrated analysis and modeling that addresses chemistry/climate processes spanning the troposphere and stratosphere. We use these capabilities to provide science and science leadership that improves understanding and directly assists public policy.

Illustrative Near-Term Goals

  • Advancing the building blocks that underlie science and policy: improved understanding of climatic extremes; identification of changes in circulation, chemical transport, and links to climate; improved evaluation of climate change metrics such as Global Warming Potential (GWPs); more complete projections of future global hydrofluorocarbon (HFC) emissions.
  • Leadership in the science community and at the science/policy interface: provisioning of improved and more comprehensive estimates of emissions of greenhouse gases and aerosol precursors used in modeling; leadership of international water vapor scientific assessment; leadership in comparison of stratospheric ozone climatologies used in modeling; developing of an improved stratospheric aerosol climatology.

Collaborations

The group collaborates widely, as indicated in our publication lists. Key collaborations include those with other research groups in CSD and GMD, other NOAA units including NCDC and GFDL, and with NCAR, industry, EPA, NASA, NSF, academic and government institutions in the U. S. and overseas, and international research organizations (IGBP, WCRP).
