Atmospheric Deposition

Study Number: 169

Project ID: 


Funding Source: 



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.

Wetfall occurring as precipitation is collected after each event with a sample size large enough to analyze. Dryfall is collected monthly. Each sample is analyzed for NO3, NH4, Cl, SO4, Ca, Mg,Na, K, Total N, & Total P. Inclusion of Dissolved Organic Nitrogen began with 1998 data.
