Global inventory of nitrogen oxide emissions constrained by space-based observations of NO2 columns

sions (37.7 Tg N yr #1 ) agrees closely with the GEIAbased a priori (36.4) and with the EDGAR 3.0 bottom-up inventory (36.6), but there are significant regional differences. A posteriori NO x emissions are higher by 50 -- 100% in the Po Valley, Tehran, and Riyadh urban areas, and by 25 -- 35% in Japan and South Africa. Biomass burning emissions from India, central Africa, and Brazil are lower by up to 50%; soil NO x emissions are appreciably higher in the western United States, the Sahel, and southern Europe

ECONOMIC VALUATION OF ACID DEPOSITION DAMAGES

This paper summarizes estimates of the monetary value of the physical damages that acid deposition causes in the United States. These estimates were developed for the Interim Assessment of the National Acid Precipitation Assessment Program (NAPAP) but were not included in the final version of the assessment report. This paper describes this research and discusses why these estimates received so little support within the NAPAP. It outlines the role of economics in the current Integrated Assessment and discusses the extent to which lessons learned earlier have been integrated into the current assessment.

Regional Influences and Environmental Policymaking: A Study of Acid Rain

A four-region classification of states is used to examine the impact of regionalism on the acid rain policy debate. It was found that a state\u27s activity level was significantly influenced by its commitment to environmental protection and its regional differentiation
