Emissions Database for Global Atmospheric

In addition to the extensive chemical reactions, forecast runs include CO tracers which are tagged with their origin. Such tracers are emitted normally over selected regions (north and south China, Japan, south Asia, northern America, Europe, and Siberia) and evolved subject to model transport schemes and normal chemical loss processes for CO. Anthropogenic surface emissions of CO are taken from the Streets et al. (2003) inventory over Asia (except China), and from the Emission Database for Global Atmospheric Research (EDGAR) (Olivier et al. 1996) over other regions. Surface CO emissions over China are taken from D. Streets,...

Figure 6.22. Observations of CH3CCI3 and CFC-11 from the Atmospheric Lifetime Experiment/ Global Atmospheric Gases Experiment (ALE/GAGE) and Climate Monitoring and Diagnostics Laboratory (CMDL) databases, respectively. The projections from the baseline emission scenario of WMO/UNEP (1998) are shown for comparison. The scenario includes estimated industrial production and emission for each year (including the effects of delayed release in some applications such as refrigeration, see WMO/UNEP, 1998). The methyl chloroform data show a rapid decline observed in recent years due to reduced emissions and the 5-year lifetime of this gas (Prinn et al, 1995 WMO/UNEP, 1998), while the CFC-11 abundances have just passed their peak (Elkins et al, 1993 Montzka et al, 1996 updated courtesy of J. Elkins and S. Montzka) and are projected to decline slowly in the future due to the 50-year lifetime of this gas. From Solomon (1999).
