| Abstract |
Plane-integrated (PI) open-path Fourier transform infrared spectrometry (OP-FTIR) has been used to measure the flux of ammonia and methane from a hog waste lagoon before and after the installation of a bioactive cover. A computed tomography algorithm using a smoothed basis function converts the measured PI concentrations into a plume profile. Simultaneously collected wind data are integrated across the plume to yield the emission flux. Seasonal data are reported, beginning with summer data collected before and after the cover installation through the following spring. Emission data from the naturally ventilated finishing barn feeding this lagoon are also presented. |
