Comment on “Microlysimeter station 1 for long term non-rainfall water input and evaporation studies” by Uclés et al. Academic Article uri icon


  • Non-rainfall atmospheric water input, whether fog, dew, or water vapor adsorption, has indeed been recognized as an important water source in arid and semi-arid environments, as rightly detailed by Uclés et al.(2013). In these environments, the magnitude of latent heat flux during the dry season is very small and largely determined by non-rainfall water inputs (NRWI) and their evaporation, a fact that poses some very special technical measurement difficulties (Ninari and Berliner, 2002). In such conditions, even small measurement errors may result in errors that are of the order of magnitude of the flux itself (Agam et al., 2004). Measurement methods for detecting the typically small amounts of NRWI have been developed in the last several decades, starting with manual qualitative methods in the 1940s (Duvdevani, 1947) and continuing with various methods based on artificial condensation …
