The Ammonia Workshop took place Oct 22-24, 2003, in Washington, D.C., in conjunction with the annual National Atmospheric Deposition Program (NADP) meeting. This workshop was a follow-up to the 2nd International Nitrogen Conference held October 2001 in Potomac, MD, which recognized the need to improve our understanding of atmospheric ammonia .It was intended for scientists and policy-makers and addressed the state of science of ammonia/ammonium emissions, air concentrations, and atmospheric transport, transformation, and deposition. It consisted of plenary sessions with invited speakers, question-and-answer sessions, and a poster session on Wednesday evening. The presentations included here are from the plenary sessions.

Proceedings, which include abstracts from all presetners of the Annual NADP Meeting are avaliable here:
