2014/2/24
Experimental device was created to model stable atmosphere. h e device consists of the glass vessel fi lled with air. Volume of the vessel is 30 litres. h e ammonia concentration is similar to s...
The influence of gas-particle partitioning and surface-atmosphere exchange on ammonia during BAQS-Met
gas-particle partitioning surface-atmosphere exchange ammonia during BAQS-Met
2011/1/19
The Border Air Quality and Meteorology study (BAQS-Met) was an intensive field campaign conducted in Southwestern Ontario during the summer of 2007. The focus of BAQS-Met was determining the causes of...
Review and parameterisation of bi-directional ammonia exchange between vegetation and the atmosphere
bi-directional ammonia exchange vegetation the atmosphere
2010/11/29
Current deposition schemes used in atmospheric chemical transport models do not generally account for bi-directional exchange of ammonia (NH3). Bi-directional exchange schemes, which have so far been ...
Occurrence of gas phase ammonia in the area of Beijing (China)
gas phase ammonia the area of Beijing (China)
2010/10/11
The atmospheric concentrations of gaseous ammonia have been measured during two field campaigns in the winter and in the summer of 2007 at Beijing (China). These measurements were carried out by means...
Long term measurements of sulfur dioxide, nitrogen dioxide, ammonia, nitric acid and ozone in Africa using passive samplers
sulfur dioxide nitrogen dioxide ammonia nitric acid ozone Africa passive samplers
2010/8/16
In this paper we present the long term monitoring of ambient gaseous concentrations within the framework of the IDAF (IGAC-DEBITS-AFRICA) program. This study proposes for the first time an analysis of...
Corrigendum to “The role of ammonia in sulfuric acid ion induced nucleation”published in Atmos. Chem. Phys., 8, 2859–2867, 2008
ammonia sulfuric acid ion nucleation
2009/10/9
We have found some numerical errors in our paper “The
role of ammonia in sulfuric acid ion induced nucleation”
by I. K. Ortega et al. (Atmos. Chem. Phys., 8, 2859–
2867, 2008). We discovered that i...
Modelling the impacts of ammonia emissions reductions on North American air quality
ammonia emissions reductions North American air quality
2009/10/9
A unified regional air-quality modelling system (AURAMS) was used to investigate the effects of reductions in ammonia emissions on regional air quality, with a focus on particulate-matter formation. T...
Ammonia in positively charged pre-nucleation clusters: a quantum-chemical study and atmospheric implications
positively charged pre-nucleation clusters quantum-chemical study atmospheric implications
2009/6/22
The quantum-chemical treatment of pre-nucleation clusters consisting of atmospheric nucleation precursors is critically important for the understanding of the molecular nature of atmospheric nucleatio...

2009/5/6
As part of a field campaign in the framework of the NitroEurope project, three different instruments for atmospheric ammonia (NH3) measurements were operated side-by-side on a managed grassland site i...
Characterization of Atmospheric Ammonia over Xi’an, China
NH3 NH4 + Aerosol Agricultural activity
2016/3/25
Continuous measurements of atmospheric ammonia (NH3) between April 2006 and April 2007
