CO2 Laser Based N2O Photoacoustic Monitor

The indoor/outdoor exchange of air by natural ventilation is one of the most important of the physical processes taking place in greenhouses and livestock buildings, as it directly affects the microclimate within the agricultural objects. This is of vital horticultural and economic importance during crop tillage for optimization of yield, and hence the quantification of the basic greenhouse processes and their incorporation into a dynamic physical model is being studied intensively [1, 2].
