Using the air quality, meteorological and emissions data base available in the Los Angeles area, two days with distinctly different meteorology are simulated using a photochemical grid model (Urban Airshed Model). The data base used to generate model inputs is then degraded for the purpose of noting which data are most essential to collect in order to have a complex grid model perform adequately. The results are used to develop a more general methodology for prioritizing data needs. The methodology considers model sensitivity to input derived from data bases of varying detail, expense in collecting the data, and the uncertainty associated with deriving model input variables from the data base.
