Methodology and results of the REKLIP atmospheric emission inventory of the upper Rhine Valley transborder region

In the frame of the climatological project REKLIP which involves part of Sw itzerland, Germany and France and concerns the upper Rhine valley, an atmos pheric emission inventory has been established with a spatial resolution of a square kilometer and a time resolution up to one hour. Anthropogenic emi ssions of SO2, NOx, CO, HCl and volatile organic compounds (VOC) divided in to thirty compounds or group of compounds as well as biogenic emissions of NMVOC have been taken into account for the year 1990. This inventory has be en updated for the following years until 1993 and some hourly emissions inv entories have been derived for a period of several days of September 1992, corresponding to a REKLIP intensive measurement campaign.
