Emission inventories: a few issues Claire GRANIER Service d’Aeronomie / IPSL, Paris, France Also at: Max Planck Institute for Meteorology, Hamburg, Germany and CIRES/NOAA Aeronomy Laboratory, Boulder, USA
Development if international databases Within: the GEIA (Global Emissions Inventory Activity) project of IGBP Co-chairs: A. Guenther (NCAR, Boulder, USA) and C. Granier the ACCENT (Atmospheric Composition Change) European Network Version 2 of the GEIA database developed as part of ACCENT http://www.accent-network.org First (global) inventories of GEIA-2 will be released ~ June, 15 POET (1990-2000) RETRO (1960-2000) Tools will be soon available: visualization comparisons regridding formats
A few issues Consistency between inventories: gaseous/aerosols and VOCs speciation spatial: local, regional and global More links between communities: national/international and international projects (organize an international workshop?) Natural emissions from static inventories to interactive parameterizations/models to take into account impact of meteorology, climate change and land-use change. Database of ancillary data under development within GEIA and ACCENT (more participants welcome). Verification of emissions intercomparisons of inventories and input data (emission factors, activity data, fire counts/area burned, etc.) Inverse modeling : is currently limited to a few species (CO, NO2) at the global scale. Has started to be used for local/regional emissions. Methods still under development, an intercomparison could be organized.
