This unique volume summarizes and integrates more than a decade of atmospheric chemistry research, carried out under the auspices of the International Global Atmospheric Chemistry (IGAC) Project of the International Geosphere-Biosphere Programme (IGBP). It is part of a series being written by each of the IGBP core projects. During the period under consideration, great progress has been made in the science, computing, modelling and observational techniques; methods have also improved. Suggestions for the highest priority research for the next decade are made. The volume was written by leaders in the field of atmospheric chemistry research, and includes important information regarding impacts on the environment reinforced by solid scientific results.

This book was written by over 20 lead authors with significant contributions from over 130 contributing authors All of the authors are recognised leaders in the field of atmospheric chemistry research and participants in the International Global Atmospheric Chemistry Includes supplementary material: sn.pub/extras

"This volume summarizes and integrates more than a decade of atmospheric chemistry research. During the period under consideration, great progress has been made in computing, modeling, and observational techniques, and methods have also improved. Here, suggestions for the highest priority research for the next decade are made, and important information is related regarding impacts on the environment."
