Research Category: Air Quality and Air Toxics , Climate Change , Air
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 air quality decision makers.
Progress Summary:
As noted in the prior progress report, one of the main activities of year 2 was to prepare meteorological fields for the current years (2008-2010) and future (2049-2051) by downscaling GISS Model E output using WRF. This was completed, and written up as a journal submission (Trail, et al., 2012), which is to be submitted shortly. Through the analysis of the meteorological variables that most strongly influence air quality we found consistent changes in regional climate that would enhance ozone levels in four regions of the United States during the fall, one region during the summer, and one region where changes potentially would lead to better air quality during the spring. We now are in the process of using MARKAL modeling results to simulate air quality for a base case future emissions scenario in CMAQ. MARKAL modeling of climate strategy impacts on air quality-relevant emissions is under way. (Recall, many more MARKAL runs are conducted than can be simulated using the detailed air quality system.) Another major focus of this year has been simulating the impact of forest changes that might result from greater use of forest products for production of cellulosic fuels. The meteorological portion was completed, and written up as a journal submission (Trail, et al., 2012), which currently is undergoing peer review. Our simulations suggest that afforestation in the Southeastern United States can cause warming in the future while cropland has a cooling effect. We also will simulate the air quality impacts of afforestation using the CMAQ model and the base case future emissions from MARKAL.
Another achievement of the project was a modification to the regional meteorological model we are using, WRF, that we call “Loop Noah” (Liu, et al., in preparation). In this extension of WRF, the code has been modified such that we can better track the impact of specific land uses on meteorology, and are able to simulate the subgrid scale skin temperatures by land use (as opposed to using just the dominant land use).
Future Activities:
The focus of our activities over the coming year are:
- 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.
- Prepare pollutant concentration fields for the current years (2008-2010) and future (2049-2051) by using WRF downscaling results and MARKAL/SMOKE emissions as inputs to CMAQ.
- Prepare pollutant concentration fields for the year 2050 simulating forest management practices.
We will be using a variety of computational resources (servers, disk arrays). The programs to be used include WRF/SMOKE/CMAQ.
