Summary: Non-rainfall water (NRW) is an important water source for ecosystems, but often overlooked due to its small quantity. We have developed a novel micro-lysimeter system that accurately measures NRW inputs and distinguishes between different types of NRW. The system has been proven to be useful in short-statured grasslands.

Summary: This study investigated the effects of dust agglomeration dynamic factors on PV surfaces using micro-experiments and mechanical analysis. An experimental platform for dust particle agglomeration due to condensation was designed and developed, and microscopic experiments were conducted to study the dust particle agglomeration process on the PV panel surface. The results provide theoretical guidance for reducing the dust deposited on PV surfaces by understanding the particle agglomeration mechanism caused by condensation.

Summary: Atmospheric water harvesting is a promising solution to the clean water shortage, with two main methods of water collection: capturing water from fog and condensing vapor on surfaces. The research shows that superhydrophobic surfaces play a crucial role in fog collection efficiency, while dew harvesting efficiency depends on a combination of drop mobility and nucleation rate.

Summary: The study proposes a new mist dew collector that mimics natural creatures to improve efficiency of water collection. The system features a gradient structure and Janus sponge for storage, improving collection efficiency by adjusting liquid behavior throughout the process. Compared to traditional fog collection structures, this system shows significant improvement in efficiency.

Summary: Foliar water uptake (FWU) is a common approach for plants to acquire water under water-limited conditions. However, most research on FWU has focused on short-term experiments, and the long-term response of plants to FWU remains unclear. In this study, the effects of long-term and short-term FWU on leaf water potential, gas exchange parameters, and fluorescence physiological parameters of Calligonum ebinuricum were investigated. The results showed that short-term FWU did not alleviate drought stress, while long-term FWU significantly improved plant water status and promoted photosynthetic activity. This study provides valuable insights into the drought-tolerant survival mechanism of plants in arid regions.

Summary: The study found that the uptake of non-rainfall water inputs by biocrusts is influenced by biocrust type, and the effects of non-rainfall water inputs on CO2 fluxes vary. Fog mainly stimulates respiration of biocrust-covered soils, while dew has a greater effect on biocrust photosynthesis.

Summary: This study evaluated the structure and composition of lichen-dominated hypolithic communities found in the coastal zone of the Namib Desert, which differed in bacterial composition and structural organization from those found in inland areas, possibly due to specific microenvironmental conditions. Additionally, moisture derived from fog and dew could be the main driver of this unique hypolithic colonization.

Summary: Janus wettability applied to mesh geometry can enhance fog-harvesting performance. A superhydrophilic back in a Janus mesh provides the highest fog-harvesting yield by enhancing water drainage, while a superhydrophobic front produces lower fog-harvesting performance. Some Janus treatments can also prevent mesh hole clogging.

Summary: The turbulent boundary layer concepts have been extended to include aerosols and gravitational settling. Interactions between aerosols and the Earth's surface are represented via a roughness length for aerosol, and gravitational settling impacts vertical profiles and surface deposition of aerosols. Simple profile solutions can be used to predict deposition velocities and illustrate the dependence on reference height, friction velocity, and gravitational settling velocity.

Summary: The study aims to enhance the efficiency of conventional green roofs by introducing a new multipurpose green roof combined with fog and dew harvesting systems. Analysis shows that fog harvesting can fulfill the total water demand of green roofs in different climates, while dew harvesting by PV panels can provide 15 to 26% of the water requirements.

Summary: This paper proposes a TCF compensation recognition method using a MEMS piezoelectric cantilever as a dew point sensor to improve the accurate measurement performance. This method analyzes the sources of previous errors, identifies the dew point using only the influence of TCF and relative humidity on the resonant frequency, and determines the dew point by iteratively calculating the intersection point. Experimental results demonstrate a measurement error of 0.33 degrees Celsius for this method.

Summary: During dry periods in temperate grasslands, non-rainfall water (NRW) has an important impact on leaf surface water balance and plant water status. Previous studies overlooked the role of radiative cooling in air-leaf water exchange, which prompted us to conduct a field study investigating the effect of radiatively-induced NRW inputs on leaf water isotope signals and air-leaf water exchange in a temperate grassland. Our results revealed the ecological relevance of radiative cooling and leaf wetting in temperate grasslands, which has implications for land surface water budgets and plant survival in a drier climate.
