Ammonia Monitoring Network, a new NADP Initiative


A motion was made at the 2007 NADP Executive Committee meeting in Annapolis, Maryland (June 12-13, 2007) to consider a special study with a goal of establishing an ammonia monitoring network. This network would measure atmospheric concentrations of ammonia gas using low-cost, passive samplers at a number of sites across North America.
