Abstract
Fugitive emissions of methane (CH4) and carbon dioxide (CO2) from a lagoon containing biosolids were continuously measured using an eddy covariance system for three months. Open Path Fourier Transform Infrared Spectrometry (OP-FTIR) was also used to quantify concentrations of methane and ammonia (NH3) at several locations along the lagoon edges for four days. Both eddy covariance and inverse dispersion (using a backward Lagrangian stochastic model–WindTrax) techniques were used to quantify fugitive emission fluxes of methane, carbon dioxide and/or ammonia. For the data obtained by the eddy covariance system, the relationships between concentrations/emission fluxes and temperature, wind speed, and wind direction were studied and certain trends were identified. While the predominant wind direction was not ideal for the sonic anemometer measurements, emission fluxes for methane simulated using inverse dispersion and eddy covariance techniques were consistent with each other for the same time periods.
