Abstract

Estimation of biogenic emissions of nonmethane volatile organic compounds from Catalonia R. Parra & J.M. Baldasano Environmental Modelling Laboratory Universitat Polit2cnica de Catalunya (UPC), Spain. Abstract The magnitude, and the superficial and temporal distribution of non-methane volatile organic compounds (NMVOC) emitted by vegetation in Catalonia for the year 2000 have been estimated, as a first step to using a chemical transport model (CTM). Vegetation represents an important source of isoprene, monoterpenes and other volatile organic compounds (OVOC) whose interactions and reactions in lower troposphere are important constituents involved in photochemical pollution episodes. This estimation was developed using a high-resolution land-use map (squared cells of 1 km2) that differentiates twenty-two categories. Air temperature and solar radiation for the year 2000 were collected from different meteorological surface stations. We have used a standard biogenic emissions mathematical model
