Ammonia as one of the air pollutant mostly originated from agricultural activities, such as manure and soil management. There is a need for precise and reliable quantification of ammonia emissions which is easy applicable on field or laboratory conditions. Cavity ring-down spectroscopy device Picarro G2508 measures ammonia (NH3) concentrations along greenhouse gasses, namely nitrous oxide, methane, carbon dioxide and water vapour content. The aim of the study is to develop methodology for NH3 measurements for Pica...

The Greenhouse gas (GHG) emission reduction is one of goals of environmental policy in climate change context. The accuracy of Soil flux measurements is one of scientific challenges during last decades. The soil flux measurement methodology using gas chromatography is described and commonly used. However cavity ring down spectroscopy is relatively new technology and there is need to research optimal chamber configuration and measurement time. The aim of this study is to evaluate three types of static chamber confi...
