Emission inventory for Nigeria with CAREAIR.

CAREAIR is the abbreviation for "Computer aided Analysis of Reduction strategies for Emissions and ambient AIR pollution". It is a modelling-system for air pollution analyses including a flexible emission model developed at the IER. The PC-based version of the system is especially designed for applications in so-called 3rd-world countries, but in fact it can be used for any country. A modeling database for many emission relevant processes and related emission factors is part of it. This paper first gives a short overview on the capabilities of CAREAIR and secondly presents part of the emission inventory for Nigeria, which has been elaborated using CAREAIR during a cooperation between the University of Stuttgart (FRG) and the Obafemi Awolowo University of Ile-Ife (Nigeria). In particular estimates of the yearly emissions of total Hydrocarbons (VOC = Volatile Organic Compounds), divided into CH4 (Methane) and NMVOC (Non-Methane-VOC), NOx (Nitrogen Oxides), N2O (Nitrous Oxide), CO2 (Carbon Dioxide) and CO (Carbon Monoxide) emissions in Nigeria 1989 are given.
