Abstract The report describes the processes, assumptions, and data sources used in developing the National Acid Precipitation Assessment Program (NAPAP) temporal, spatial, and species allocation factors. The processing of the NAPAP emissions inventory through the Regional Model Data Handling System (RMDHS) and the specifications for a new NAPAP data handling system are also detailed. The Eulerian acid deposition model being developed for use in the NAPAP required more resolved emissions data than are available in the NAPAP emissions inventory. The NAPAP inventory, which separately covers annual emissions from point and county-wide area sources, had to be apportioned to reflect hourly emissions with area source emissions assigned to grid squares. Hourly emissions of volatile organic compounds (VOCs) then had to be allocated into photochemical reactivity classes and nitrogen oxides (NOx) emissions had to be separated into NO and NO2.
