Water vapor flux plays a crucial role in surface-atmosphere exchange processes as evapotranspiration regulates the energy balance of the surface. Moreover, it transfers water vapor into the atmosphere and, as a result, shapes the hydrological cycle.

In parameterization of the bi-directional ammonia exchange models over vegetated surfaces there are three most crucial parameters: (1) the stomatal (χs) and (2) the soil (χg) compensation point concentrations as the function of Γ=[NH4+]/[H+] in th

Ammonia is one of the most significant environmental pollutants. Concentration measurements, identifying the sources and studying the transformations in the biosphere are essential, and they are the focus of many investigations. The near-infrared (

A detailed study on the pressure dependent sensitivity of a wavelength modulated diode laser based photoacoustic (PA) water vapor detection system is presented. It is shown that the pressure dependence of sensitivity is primarily determined by the pr
