The ICHM is primarily a web-based organization, communicating by email and publishing electronically. We aim to:

• promote the scholarly study of the history of meteorology, climatology, and related sciences including their social and cultural aspects;
• facilitate international cooperation, communication, and friendship between historians and scientists;
• organize symposia at the International Congresses of History of Science, to sponsor or co-sponsor other meetings of similar character, and to disseminate the proceedings of these meetings;
• promote identification, collection, preservation, and access to historical materials;
• encourage the compilation of international historical bibliography;
• support the broader goals of the DHS, IUHPS, and ICSU (International Council of Scientific Unions).

Founded in 2001 in Mexico City, the ICHM now has about 300 members from 49 countries. The Commission publishes a peer-reviewed journal,History of Meteorology, and regularly organizes conferences, workshops and panels at interantional meetings devoted to the history and social studies of atmospheric sciences. We had major meetings in Washington D.C., Weilheim (Bavaria), Rio de Janeiro, and Athens.Membershipis free, and open to anyone with an interest in the history of meteorology and weather.
