Methane fluxes from the manure ponds had a robust diurnal pattern, increasing with air and surface pond temperatures. As such, latent heat flux and CH4 flux also had a strong positive diurnal relationship, especially during the pre-sedimentation stage. Higher wind speed and friction velocity also increased diurnal maxima of CH4 fluxes. Rising lagoon temperatures and…

Whole-air samples were collected at the same height of the mobile laboratory inlet
Continuous measurements of greenhouse gases and pollutants were collected using a mobile platform , consisting of analyzers using the Cavity Ring-Down Spectroscopy technique , global satellite positioning unit to record geolocation and vehicle speed, 2-D sonic anemometer to measure wind direction, wind speed, air temperature and relative humidity, and calibration tanks. The following trace gas…
