The American Meteorological Society was founded in 1919 for the purpose of collecting and disseminating research about meteorological and atmospheric sciences. It has approximately 14,000 members and 9 published journals. It also holds exhibits, hosts conferences, and supports recruitment into the field of meteorology by providing educational resources at all levels of the career path: from the K-12 level to the job search stage. The AMS provides certificate programs for meteorology and hosts policy discussions on climate change and other climate-related public policy issues. Its headquarters are in the historic home of Boston's third mayor, Harrison Gray Otis, which was built in 1806 and renovated for its current purpose in 1958.
