Press releases and media information are also available, as is an analysis of environmental and sustainability issues and a picture library. It also aims to ensure the long-term integrity of atmospheric data produced by NERC projects. The site contains a large archive of documentation reporting past experimentation and projects and links are also provided to the conference proceedings for all subject-related conferences that were previously publicised on the site. The site provides two major resources - a gallery of maps which illustrate the spatial relationships between emissions and the environment, and a download facility. This allows you to download GIS datasets to be uploaded into GIS software, or a spreadsheet.
Categories covered include air, water, land, deposition and emissions.
The data covers the North American continent. Useful sources available from this site include access to relevant datasets, as well as bibliographic descriptions of CMDL publications. The 1998 Earth Science Enterprise Applications Fact Book provides details of eleven applications that NASA are using to monitor and analyse environmental change. This site provides the full text of a report published by the National Academy Press in 2000. The report was produced by the US Commission on Physical Sciences, Mathematics, and Applications.
