“…The fog frequency was, in general, somewhat higher at Lulin than at Xitou. The percentage of fog days (minimum 1 hour of fog per day) was 80% -90% at Lulin and 70% at Xitou, which is within the range of earlier studies at the same sites (Simon et al, 2016;Breuer et al, 2021). The main technical goal of all three IOPs was to collect as many back-to-back samples as possible within single fog events.…”

This study used a water volume-based sampling method in combination with an active fog collector (modified Caltech design) to collect fog water samples during three intensive operation periods at two mountainous study sites in Taiwan. The new setup employed a sample-volume controlled system that dosed the fog water into 10 ml aliquots, which were then collected with a commercial laboratory auto-sampler. We collected fog water samples about 10 times more frequently (median sampling period 3 minutes and 45 seconds) than with traditional sampling schemes. Notably, up to over 200 samples were collected within a single fog event lasting 13 hours. The results showed that the intra-event variabilities of pH (up to over 2 units), conductivity (range almost 1000 µS cm -1 ), and ion concentrations were generally higher than the inter-event variability. The variabilities exhibited particularly fast changes during phases of fog onset and dissolution; in contrast, the centers of the passing clouds at our mountain research sites were rather homogeneous. Overall, our new method showed a marked improvement in sampling speed over traditional methods.

“…For instance, studies have found that the amount of atmospheric condensate could reach 5.0% to 16.2% of the annual precipitation in the Negev Arid in Israel, the Nevada Desert in the United States, and the Atacama Desert in Chile [ 17 , 18 , 19 ]; thus, atmospheric vapor is an important water source for the ecosystems in those arid and semi-arid regions [ 20 , 21 ]. The condensed water converted from atmospheric vapor recharges soil moisture and also directly improves the physiological status of plant leaves [ 22 ]. Some studies report that night dew could change the water shortage of Ponderosa pine (Pinus ponderosa) and extend its survival time under drought stress [ 23 , 24 ].…”

The ability of plants to absorb unsaturated atmospheric water vapor is a controversial topic. To study how vegetation in arid areas survives under limited water resources, this study uses Tamarisk in the Ulan Buh Desert of China as an example. The in-situ observation of a newly designed Lysimeter and sap flow meter system were used to monitor the precipitation infiltration and the utilization efficiency of Tamarisk of atmospheric vapor. The results show that the annual precipitation of 84 mm in arid areas could still result in deep soil recharge (DSR) with a recharge rate of 5 mm/year. Furthermore, DSR is detectable even in the winter, and the 5-year average DSR was 5.77% of the annual precipitation. It appears that the small precipitation events are critically important for the survival of Tamarisk. When the atmospheric relative humidity reaches 70%, Tamarisk leaves can absorb the unsaturated atmospheric vapor, which accounts for 13.2% of the annual precipitation amount. To adapt to the arid environment, Tamarisk can harvest its water supply from several sources including atmospheric vapor and micro-precipitation events (whose precipitation is below the measurement limit of 0.2 mm of the precipitation gauge) and can still permit a certain amount of recharge to replenish the deep soil moisture. Such an ecohydrological dynamic is of great significance to desert vegetation.
