“…In Hebei Province, dust and soil were sampled from the affected area and the control area [ 46 ]. Several other studies that conducted precipitation and surface water sampling after hail suppression also confirmed that the silver content of the samples after silver iodide seeding was higher than that before seeding or in the comparison area [ [47] , [48] , [49] , [50] , [51] , [52] , [53] ]. However, these studies did not focus on the transport pathway of silver iodide catalyst after seeding.…”

“…As seen in Table 3 , taking Moldova as an example, the Ag + concentration in the reservoirs affected by artificial precipitation was 1.7–7.4 μg L −1 , while the Ag + concentration in the reservoirs of the comparison area was 0.9–4.1 μg L −1 [ 23 , 53 ]. The silver content data of the 495 surface water bodies collected in Beijing from 2021 to 2023 were 0.07–0.42 μg L −1 .…”

“…However, for seeding method, the operational effectiveness of artificial rainfall is severally affected by the ambient environment, droplet size distribution, and seeding height. Meanwhile, there are several major difficulties in promoting the seeding technology (Wu et al, 2018), which include the high cost of operation, the risk of pollution (Fisher et al, 2018;Korneev et al, 2017), and the efficient method for evaluating rainfall enhancement. Thereafter, emerging technologies, such as acoustic coagulation (Galechyan, 2005), laser-induced condensation (Leisner et al, 2013) and atmospheric ionization (Tan et al, 2016), have attracted more attention.…”

For securing sustainable water resources, traditional solutions including seawater desalination are limited due to high cost and restricted operating conditions.Plateau. Statistical analysis was applied to evaluate the effect of acoustic wave on rainfall stimulation. The results of average rainfall intensity distribution using ordinary least square analysis disclose that acoustic interference has a considerable effect on rainfall enhancement. Such a rainfall enhancement effect increases significantly along with the increase of rainfall duration which is the index of cloud precipitation potential.For rainfall events with the duration more than two hours, the average rainfall intensity was improved by 72% with the acoustic wave effect over the experiment site. The phenomena are consistent with the fact that clouds with larger precipitation potential contain more cloud droplets which are beneficial to the acoustic coagulation process.

“…However, cloud seeding can have environmental impacts correlated with the injection of chemicals into the atmosphere. These effects include, but not limited to, toxicity among humans and wildlife (Korneev et al 2017). In addition to its local environmental impact, chemicals generated via cloud seeding can move over land and ocean and can be deposited over coastal waters, which enhances chlorophyll concentration (Singh et al 2004, Prasad et al 2004, Kambezidis 2010.…”

In this study, satellite data and those obtained from air quality monitoring stations were used to evaluate the effect of cloud seeding missions conducted from January 2017 to March 2017 in the United Arab Emirates (UAE). To determine PM variability during and after the cloud seeding missions, information on daily mean particulate matter (PM 10 and PM 2.5 ) concentrations obtained from 20 air quality ground-based stations was analyzed from January 2017 to April 2017. The stations were divided according to four distinct geographic zones, which include petrochemical and non-petrochemical industrial, residential, and low populated areas. Moreover, data from the MAIAC 1-km product (MCD19A2) obtained using the Moderate Resolution Imaging Spectroradiometer onboard the Terra satellite were used to identify the correlation between aerosol optical depth and ground PM concentrations. The results showed that among the areas, the petrochemical and nonpetrochemical industrial areas had the highest PM 2.5 levels. Urban areas located adjacent to deserts had significantly higher PM 10 concentrations than other urban areas. The PM concentration was high during the period of cloud seeding missions. This finding indicated that silver iodine crystals fired during the missions might have increased the concentration of PM in the air. Moreover, cloud seeding missions might have a more significant effect in increasing PM 10 concentrations compared with PM 2.5 concentrations. Hence, local weather conditions might have affected the decay of silver iodine particles during the missions. Long-range air mass transport may have an influence on the natural and anthropogenic particle concentrations in land and water bodies surrounding the UAE.
