Data from bi-weekly passive samplers from 18 of the longest operating National Atmospheric Deposition Program’s (NADP) Ammonia Monitoring Network (AMoN) sites (most operating from 2008 to 2015) show that concentrations of NH3 have been increasing (

Ammonia (NH3) emissions from fertilizer application is a highly uncertain input to chemical transport models (CTMs). Reducing such uncertainty is important for improving predictions of ambient NH3 and PM2.5 concentrations, for regulatory and policy p

Wet deposition was measured in two urban areas of Brazil, Cubatao and Sao Paulo megacity (MASP), from July 2009 to August 2010. Cubatao is characterized by the large and complex industrial sector and MASP by a large vehicular fleet, and these differe
