International Association of Meteorology and Atmospheric Sciences

Purpose and Objective

IAMAS is one of the eight associations dealing with the Earth system and its environs that make up the International Union of Geodesy and Geophysics (IUGG). The scope of IAMAS includes the atmospheres of the Earth and other planets. IAMAS is made up of ten international commissions and one committee which together play a major role in implementing IAMAS’s activities. The ten commissions cover Atmospheric Chemistry and Global Pollution (ICACGP), Atmospheric Electricity (ICAE), Climate (ICCL), Clouds and Precipitation (ICCP), Dynamical Meteorology (ICDM), the Middle Atmosphere (ICMA), stratospheric Ozone (IOC), Planetary Atmospheres and their Evolution (ICPAE), Polar Meteorology (ICPM), and atmospheric Radiation (IRC). The Committee on Nucleation and Atmospheric Aerosols (CNAA) brings together scientists covering the areas of Nucleation Theory and Experiment, Tropospheric and stratospheric aerosols, Cloud Drop and Ice Nucleation and Aerosol-Climate Interactions.

Many of these commissions play international leadership roles in their specialist areas [see]. The commissions provide an important supplement and extension to the leadership and research role of the World Meteorological Organization (WMO), which is the governmental body with a scientific scope that is comparable to that of IAMAS.
