Part I of this report presents a coordinated national blueprint for scientific investigations of biogeochemical cycles in the global troposphere. Part 11 presents much of the background information of the present knowledge and gaps in the understanding of tropospheric chemical cycles and processes from which the proposed program was developed. Review papers in Part II discuss the sources, transport, transformation, and removal of trace species in the troposphere; the role of modeling in understanding tropospheric chemical processes; tropospheric chemical cycles; and instrumentation development needs. An instrument andlatform_ surv-e is presented. 17. Doeurrwnt Anslyels d.

The members of the committee responsible for the report were chosen for their special competences and with regard for appropriate balance. This report has been reviewedby agroup other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The National Research Council was established by the National Academy of Sciences in 1916 to associate ihe broad community of science and technology with the Academy's purposes of furthering knowledge and of advising the federal government. The Council operates in accordance with general policies determined by the Academy under the authority of its congressional charter of 1863, which establishes the Academy as a private, nonprofit, self-governing membership corporation. The Coun- cil has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in the conduct of their services to the government, the public, and the scientific and engineering communities. It is administered jointly by both Academies and the Institute of Medicine. The National Academy of Engineering and the Institute of Medicine were established'. in 1964 and 1970, respectively, under the charter of the National Academy of Sciences. This material is based upon work supported jointly by the National Science Foundation and the National Aeronautics and Space Administration under Grant Number ATM 80-24257.
