Bowen Ratio and Evaporation from Waste Lagoons - A low-cost
system was deployed above a swine waste lagoon to obtain
estimates of Bowen ratios and characterize lagoon temperatures.
The system consisted of humidity and temperature sensors and
anemometers deployed above the lagoon, water temperature
sensors, and a meteorological station located by the lagoon. To
evaluate the system, data was analyzed from the 25th through
28th June 2007. Bowen ratios showed diurnal behavior near the
lagoon surface characterized by negative values during day and
positive ones at night. Latent (evaporation) and sensible heat
fluxes were towards the atmosphere and the lagoon, respectively
for most of the day. A diurnal cycle in atmospheric and lagoon
temperatures was also observed. Furthermore, wind speeds above
the lagoon were highest in the afternoon. These variations were
linked to lagoon temperature strati
