- Abstract
- At the NADP Fall 2010 Meeting and Scientific Symposium, the NADP voted to approve the Ammonia Monitoring Network (AMoN) as the fifth NADP network. AMoN began its operation as a special study within NADP in October 2007, with a goal of measuring atmospheric ammonia concentrations to estimate dry deposition. These data are used to understand the distribution of ammonia in the atmosphere and environment. At the end of 2010, AMoN had 21 sites. More information about AMoN can be found on page 22 and at http://nadp.isws.illinois.edu/amon.Other highlights: At the Spring 2011 Meeting, the NADP committees voted to modify the maps from an earlier discrete contour map style (used since 1994) to a new continuous color gradient map style. These new maps also use a more highly resolved precipitation data set. Specifics of the new mapping techniques are provided on page 6 of this report. Over the past several years, the Central Analytical Laboratory (CAL) has measured the concentration of bromide ion in NTN and AIRMoN samples as part of a special study with the U.S. Geological Survey (USGS). Bromide is widely used in agricultural and industrial applications, and is being evaluated as a new NADP analyte. Data are available upon request. NADP data and maps were used in at least 146 scientific publications. A list of these can be found at the NADP website. NADP’s NTN and MDN network data were used by the U.S. EPA to evaluate the impact of the April and May Gulf of Mexico oil fires on the Gulf Coast and eastern U.S. During the year, the NADP continued the rust spore deposition special study with USDA Cereal Disease Laboratory (CDL) scientists at the University of Minnesota. In addition to continued soybean rust deposition monitoring (Phakopsora pachyrhizi, since 2005), CDL scientists began to investigate winter and spring precipitation for the presence of other pathogens, specifically wheat rusts (stem, stripe, and leaf ), corn rusts (common and southern), and sugar cane rusts (brown and orange). U.S. EPA scientists, with NADP, continued special studies to determine whether organic nitrogen deposition can be measured reliably and accurately. The results indicated that organic nitrogen can be measured reliably, and that an organic fraction can be differentiated from the inorganic fraction. This added information contributes to the understanding of nitrogen deposition patterns. During 2010, the NADP continued to install new digital precipitation gages at its wet deposition sites (see map below). As of the end of 2010, 166 sites out of 300 total sites (55%) had operating digital gages. These data are available at the NADP website
