1 Introduction Fog is a common meteorological phenomenon that can provide up to five times more moisture than rain in some fog-dependent ecosystems (Fischer et al., 2009; Garreaud et al., 2008; Olivier and Stockton, 1989; Weathers et al., 2020).

1 Introduction The stable isotopes of hydrogen (δ2H) and oxygen (δ17O and δ18O) in water have become one of the most useful tools for quantifying critical ecohydrological fluxes such as evapotranspiration partitioning [1, 2], spatiotemporal origins of plant water sources [3-5], and identification of precipitation/fog/dew origins [6-8].
