The Encyclopedia of the Atmospheric Environment is one of the outputs of the the Atmosphere, Climate & Environment (ACE) Information Programme which was supported by the UK Department for Environment, Food and Rural Affairs (DEFRA) until 2005 to disseminate information, without advocacy or bias, on the causes, effects of and controls on air pollution and climate change, within the framework of national legislation and international discussion. The Encyclopedia, developed in 2000, is now a well established and recognised online resource on atmospheric pollution and related issues, with over 400 topics and 100 accompaying photos, figures and charts. It was last updated in 2005.
