The CNAA is a committee of the International Association of Meteorology and Atmospheric Sciences (IAMAS, a constituent association of the IUGG) that is affiliated with IAMAS’s International Commission on Clouds and Precipitation (ICCP).
The International Conference of Nucleation and Atmospheric Aerosols (ICNAA) is organized by the CNAA at 4 year intervals. This conference is typically held one year following the ICCP’s related International Conference on Clouds and Precipitation.
Next ICNAA conference will be in 2029 in Suzhou, China. In 2027 we will organize a Nucleation Symposium in Helsinki, Finland.
