Open-path Fourier transform infrared spectroscopy (OP-FTIR) is susceptible to environmental variables which can become sources of errors for gas quantification. In this study, we assessed the effects of water vapour, temperature, path length, and win

Open-path Fourier transform infrared spectroscopy (OP-FTIR) has often been used to measure hazardous or trace gases from hot point sources (e.g. volcano, industrial, or agricultural facilities) but seldom used to measure greenhouse gases (GHGs) from

Poultry production significantly contributes to atmospheric ammonia (NH3) emissions, causing concerns over their environmental impacts and the effects on human and bird health inside the poultry houses. A model is needed to estimate NH3 emissions fro

A mechanistic model was developed for estimating ammonia (NH3) emission from laying hen manure based on measurements from a laboratory-scale wind-tunnel experiment. Ammonia emissions were measured continuously for 3–6 d from manure samples under 17
