Inventory

RCEI is one of the projects of the Global Emissions Inventory Activity (GEIA), an integrating project of AIMES/International Geosphere-Biosphere Program. This GEIA project developed a global emissions inventory for major, reactive chlorine species in the troposphere. Principal objectives were: 1) To develop and verify individual global emissions inventories on a 1° x 1° grid scale for particulate Cl^-, HCl, other inorganic Cl gases, CH₃Cl, CH₃CCl₃, CCl₂=CCl₂, CHCl=CCl₂, CH₂Cl₂, CHCl₃, and HCFCs; 2) To develop and verify a composite, multi-species inventory on a 1° x 1° grid scale by integrating the individual inventories; and 3) To critically assess overall uncertainties for each inventory.

Working Groups

For practical purposes, the project was divided into four working groups, which addressed the different types of sources.

Publications and Data

The results from this project were published in a series of eight sequential papers, including a brief introductory overview, in the Journal of Geophysical Research - Atmospheres Volume 104, issue D7 (15 April 1999), pages 8331 to 8440. The papers are available online with a brief description of each.

Data from this project are available on the GEIA website and from this link here.

Participants and Contacts

RCEI comprises a panel of international scientists from educational, government, and industrial agencies. The personnel page contains names and email contacts for all active participants. For general information not covered on this site, please contact the convenor William C. Keene.

Time Line

Early 1994: Thomas Graedel and William Keene organized the RCEI and began inviting potential collaborators to join the effort.
Spring 1994: William Keene briefed the Chlorine Chemistry Council (CCC) of the Chemical Manufacturers' Association (CMA) concerning the planned project and solicited financial support.
Autumn 1994: RCEI participants submitted a 2-year, research proposal to CMA.
Early 1995: CMA accepted the proposal.
June 1995: Funds were transferred to participating institutions and work on the project began.
14-15 September, 1995: First workshop in Washington, DC. Working group assignments and strategic plans.
27-28 May 1996: Second workshop in Toronto, Canada. Status reports and discussion of the work's progress.
01 August 1996: RCEI website goes online at http://groundhog.sprl.umich.edu/geia/rcei/
17-19 March 1997: The third and final three day meeting of RCEI was organized by the University of East Anglia (UEA) in Norwich. Final presentations and discussions of results and manuscripts for the planned publications took place in Blakeney, England.
July 1998: Official end of RCEI's first stage, completion and submission of manuscripts
April 1999: publication of results in Journal of Geophysical Research - Atmospheres.
July 1999: Publication of final datasets and papers on the GEIA World Wide Web server.

Data submission

RCEI has officially stopped its first stage. However, data coverage is still very limited or, in some instances, insufficient for a full inventory. We will be trying to update these inventories with new data and models from time to time. If you think that your data would fit into any of our categories, visit the link of the respective working group and contact the person heading that group or other RCEI participants. We will be more than happy to consider incorporating your work for future efforts.

Acknowledgements

The work for RCEI is funded in part by the World Chlorine Council. The contract was administered by the US Chlorine Chemistry Council of the Chemical Manufacturer's Association and by Euro Chlor for the European Chemical Industry (CEFIC). We like to thank all contributors for their voluntary time and efforts in helping to establish this inventory.
