摘要：

Increases in reactive nitrogen deposition are a growing concern in the US. Rocky Mountain west. The Rocky Mountain Airborne Nitrogen and Sulfur (ROMANS) study was designed to improve understanding of the species and pathways that contribute to nitrogen deposition in Rocky Mountain National Park (RMNP) During two 5-week field campaigns in spring and summer of 2006, the largest contributor to reactive nitrogen deposition in RMNP was found to be wet deposition of ammonium (34% spring and summer), followed by wet deposition of nitrate (24% spring, 28% summer) The third and fourth most important reactive nitrogen deposition pathways were found to be wet deposition of organic nitrogen (17%, 12%) and dry deposition of ammonia (14%, 16%), neither of which is routinely measured by air quality/deposition networks operating in the region. Total reactive nitrogen deposition during the spring campaign was determined to be 0 45 kg ha(-1) and more than doubled to 0.95 kg ha(-1) during the summer campaign (C) 2009 Elsevier Ltd All rights reserved
