This volume covers topics relating reactive atmospheric chemistry, pathways for material transport within the atmosphere, and exchanges with the land, biota, oceans, and solid earth. The emphasis is on species of relevance to global climate and global chemical budgets, as well as on the application of geochemical methods, such as isotope techniques, for deciphering pathways and rates of material exchange within the atmosphere and with other reservoirs. The topics covered here have long histories, related to their importance for problems of global climate change, the ozone layers, and other global impacts on humanity.
