This volume contains the comprehensive International Global Aerosol Program (IGAP) Plan, prepared by the ICCP/IRC/ICACGP Joint Working Group on International Aerosol Climatology Project (IACP). It consists of six reports: the Overview report and five reports produced by the IACP Subworking Groups. The Overview volume contains essentially the executive summary of the five reports (Vols. 2 through 6) and the initial reports on the "International Global Aerosol Program: A Plan Outline IACP 90-1). Five of these volumes have been published separately by the World Meteorological Organization's (WMO) Global Atmosphere Watch (GAW) and the WMO/ICSU World Climate Research Programme (WCRP); the sixth volume (Vol. 5) is published by the National Aeronautics and Space Administration (NASA).
