2007 Interim Report

Main Objectives

In 2007, the Task Force produced an interim report addressing the state of science regarding the intercontinental transport of ozone, fine particles, and their precursors in the Northern Hemisphere. This interim report was produced to inform the LRTAP Convention's review of the 1999 Gothenburg Protocol, which addresses tropospheric ozone, acidification, and eutrophication . This interim report was also prepared as a first step towards a more comprehensive assessment report, which will also address mercury and persistent organic pollutants, expected by the end of 2009.

Report History

More than 100 scientists from around the world contributed to HTAP 2007 as authors, reviewers, and contributors of modeling and analysis. The development of the report began following the 2 nd TF HTAP meeting in Moscow in June 2006. All participants in the TF HTAP were invited to nominate individual experts or volunteer themselves to participate in the lead author team. Outlines and drafts of the report chapters were posted on the web for comment at various intervals throughout the process. A complete draft of the report was discussed by the TF HTAP at its 3rd meeting in Reading , U.K. Based on the Reading meeting, the Executive Summary of the report was finalized and submitted to the UNECE's LRTAP Convention Secretariat for translation and presentation to the EMEP Steering Body and LRTAP Convention's Executive Body. The main body of the report was revised and prepared for printing.

The various versions of the report that were made available for comment are provided below in chronological order. Note that the documents below have been provided in Microsoft Word, or in Adobe PDF format (with the commenting and reviewing tools available in the free Acrobat Reader 7 enabled.)
