Atmospheric deposition as found in dryfall (dust) and wetfall precipitation has been collected and analyzed since 1983 using an Aerochem Metrics wetfall/dryfall collector located at the Jornada LTER weather station north of Las Cruces, NM, USA. Wetfall occurring as precipitation is collected after each event with a sample size large enough to analyze. Each sample is analyzed for Br, Ca, Cl, F, HPO4, K, Mg, Na, NH4, NO3/NO2, SO4, Total N, and Total P. Analysis of Sr and Dissolved Organic Nitrogen was discontinued in 2003. Dryfall data are available as a separate data package.
