We develop MOVES modeling scenarios tailored to representative counties by integrating multiple datasets. Initially, we source county-level average monthly temperature and humidity data for January and July from the MOVES default database. These values are derived from the National Climatic Data Center's average temperature records spanning 2001 to 2011, ensuring comprehensive coverage across U.S. counties. Additionally, we gather information on countyspecific MOVES fuel regions and vehicle inspection and maintenance (I/M) programs. These factors exhibit significant variability between urban and rural areas within states, particularly in regions addressing air quality concerns. Across the U.S., we identify 117 distinct combinations of fuel regions and I/M programs. Subsequently, we merge these datasets to identify distinct Climate-Fuel-I/M combinations, rounding temperature and humidity values to the nearest 10 degrees (or %), as appropriate.
