The hidden water cycle in land-atmosphere interactions – fog, dew and water vapor sources and processes in ecosystems
Session ID#: 79040
Session Description:
Non-rainfall waters (e.g., fog, dew and water vapor) are the least studied hydrological components in many ecosystems. The associated condensation-evaporation-redeposition processes, in local to regional-scale, are poorly quantified in water balances yet play an important role in ecosystem dynamics and are particularly important for water-limited systems. To fill this knowledge gap, in this session, we welcome submissions of field or model investigations of the sources and dynamics of cloud water, fog and dew in various systems as well as the effects of fog and dew on various ecosystem functions (e.g., vegetation-water relations, biogeochemical cycling, groundwater recharge). We also welcome studies examining the mechanisms of fog and dew alleviating vegetation water stress.
