“…It is speculated that this occurred because the undiluted petroleum jelly used to trap particles to the greased coupon was not fully effective, so that when particles impacted the grease at high velocity some of them did in fact rebound. It is noted that other researchers used diluted petroleum jelly (Nhokim et al 2004;Biryukov 1998) or other greases (Wu et al 1992a,b;Noll et al 1988), and the present results suggest that those are better techniques. As noted, previous studies reported that particle rebound was suppressed at high RH due to capillary adhesion.…”

Field studies of dry deposition usually measure dust accumulation over periods of days or weeks. However, long measurement periods obscure the effects of meteorological conditions on the deposition rate. Previously we developed an "outdoor soiling microscope" (OSM) in order to measure dust deposition and detachment every 10 min in the field. In this study a greased/ ungreased pair of OSMs was deployed for 51 days in the desert climate of Doha, Qatar. Stepwise regression analysis was performed to quantify the explanatory power of meteorological parameters on dust deposition and detachment rates. It was found that wind speed dominated deposition and rebound of dust particles, and produced a distinctive "threshold" response in deposition. The dry deposition results were highly consistent with a model by Kim et al. (2000) derived from outdoor experiments. By comparison, relative humidity and particulate matter concentration had less influence on dust flux rates.

“…Field studies of dust rebound are also rare. Biryukov (Biryukov 1998) found that 14% of dust impacting solar collectors in an Israel desert rebounded. (Wu et al 1992a,b) made approximate rebound measurements of various chemical species in a Tennessee forest and found that, above the canopy, rebound fraction ranged from 0.41 to 0.70.…”

“…Thus, dew amounts showed a positive linear relationship with cos (q). One should note that also for dust deposition in the Negev Desert a link was found between the amounts deposited and cos (q) (Biryukov, 1997).…”

“…Semi-arid and desert regions, characterized by low cloudiness, are the most attractive locations for solar energy production. Dust deposition on solar panels deteriorates the performance of such panels leading to significant losses in the generated power [5,6]. In addition, dust dry deposition on insulators could cause insulator flashover leading to electricity outages.…”

Dust Dry Deposition over Israel

Similar quasiperiodic year-to-year variations of dust dry deposition (DDD) with a two–three-year period were found over Israel and north-east Africa. This phenomenon of quasiperiodic interannual variations of DDD has not been discussed in previous publications. Moreover, similar seasonal variations of DDD were found over both Israel and north-east Africa, characterized by significant dust deposition in spring and a decrease in DDD from spring to autumn. These findings indicate the existence of the same causal factors for interannual and seasonal variations of DDD over the two regions, such as similar surface winds created by Mediterranean cyclones. Daily runs of the Dust REgional Atmospheric Model (DREAM) at Tel Aviv University from 2006 to 2019 were used to investigate the main features of the spatio-temporal distribution of dust dry deposition in the eastern Mediterranean, with a focus on Israel. DREAM showed that, on average, during the 14-year study period, in the winter, spring, and summer months, the spatial distribution of monthly-accumulated DDD over Israel was non-uniform with the maximum of DDD over southern Israel. In the autumn months, DREAM showed an increase in DDD over northern Israel, resulting in an almost uniform DDD pattern. The knowledge of DDD spatio-temporal distribution is helpful for understanding the negative effects of DDD on the performance of solar panels and on insulator flashover in the Israel power electric network.
