Objective:
This project has four primary objectives:
• Assess and compare how climate-responsive control choices will impact air quality
• Assess how forest management practices, including biomass fuel production will impact future air quality
• Quantify the sensitivities and uncertainties in results
• Provide decision support analyses for use by ai quality decision-makers
Progress Summary:
2nd Year: As noted in the prior progress report, one of the main activities of year 1 was to develop and test the spectral downscaling approach to be used with WRF. This was completed, and written up as a journal submission (Liu et al., 2011, below), which is currently under discussion/review. A major activity this year has been to apply that approach to GISS Model E results obtained from colleagues at GISS. A number of new routines were developed to interface the GISS outputs and the WRF model. This is now done, and we are in the process of downscaling the GISS historical and future year simulations. Our investigations of the results of the test downscaling approaches are being written up in another manuscript. MARKAL modeling of climate strategy impacts on air quality-relevant emissions has begun, and the specific simulations to be more fully tested using the WRF-SMOKE-CMAQ system are being decided. (Recall, many more MARKAL runs are conducted than can be simulated using the detailed air quality system.) We have also begun simulating the impact of forest changes that might results from greater use of forest products for production of cellulosic fuels. Our initial simulations show a small dependency of temperature on the change of land use from field crops to managed forest.
Future Activities:
The focus of our activities over the coming year are:
- Continue preparing meteorological fields for the current years (2008-2010) and future (2049-2051) by downscaling GISS Model E output using WRF, with the downscaling configuration we have tested.
- Finish conducting MARKAL modeling of strategies or technologies to mitigate climate change that also impact ozone and PM-related emission and process strategies using SMOKE.
- Finalize future biomass burning scenarios.
We will be using a variety of computational resources (servers, disk arrays). The programs to be used include WRF/SMOKE/CMAQ.
