We investigated aerosol optical properties, mass concentration, and chemical composition over a 2 year period at remote site in the Negev desert, Israel (Sde Boker, 30° 51′N, 34° 47′E, 470 m above sea level). Light‐scattering measurements were made three wavelengths (450, 550, 700 nm), using an integrating nephelometer, included separate determination of backscatter fraction. Aerosol coarse fine fractions collected with stacked filter units; concentrations determined by weighing,...
ABSTRACT The major objective of the present study was to identify relationship physiologial parameters photosynthetic system with elemental content lichen Ramalina lacera (With.) J.R. Laund. Thalli R. were collected in an unpolluted site and transplanted a national park industrial region Israel for 8 mo. Analyses activity, chlorophyll integrity, spectral reflectance, amount 11 metals performed after this period exposure. normalized difference vegetation index (NDVI), indicative reflectance...
Spectral measurements of the aerosol particle scattering coefficient σ s and optical depth τ a were conducted at Ouranoupolis (Greece, 40°23′N, 23°57′E) Sde Boker (Israel, 30°51′N, 34°47′E) between June September 1998. Measurements related to 5‐day three‐dimensional back trajectories 950, 850, 550 hPa assess influence long‐range transport from particular source regions load two sites. Our show that eastern Mediterranean basin is moderately highly polluted during summer. Daily average values...
The Syrdarya Delta, located in semi-arid and arid Central Asia, is an important water source for fertile landscapes. environmental history of the Delta (SD) during 19th 20th centuries a diverse understudied subject, its natural anthropogenic aspects changed drastically this period. As result Delta’s location, on shores former Aral Sea, there vital need to expand our understanding phases policies that led current condition. This study argues by integrating methods from social sciences...
The global distribution of Pistacia is correlated to its adaptability environmental conditions and mechanisms that had driven the genus current unique narrow latitudinal belt in between 10° North 45° North. geostatisitcal maps are shown derived probability over a period 121 Kyr before present year 2100 were calculated. tolerance trees harsh climate was related leaf phenology, evergreeness vs deciduousness, which has led geographic classification two corresponding sections corroborate recent...
An intensive field campaign involving measurement of various aerosol physical, chemical, and radiative properties was conducted at Sde Boker (also written as Sede Boqer) in the Negev Desert Israel, from 18 February to 15 March 1997. Nephelometer measurements gave average background scattering coefficient values about 25 Mm −1 550 nm wavelength, but strong dust events caused value this parameter rise up 800 . Backscattering fractions did not depend on loading generally fell range 0.1 0.25,...
The Aral Sea ecological crisis resulted from the USSR government decision in 1960s to deploy agricultural project for cotton production Central Asia. Consequently water flow decreased drastically due regulation of Amydarya and Syrdarya Rivers irrigation purposes 55-60 km3 1950s 43 1970s, 4 1980s 9-10 2000s.

The Aral Sea Basin is considered as a region with increased rates of atmospheric air pollution by aerosols arid origin. It conditioned the aridity climate and presence great number natural sources emission to atmosphere. average annual days dust storms varies from 20 67, while maximum reaches up 108-146 in separate years. dusty salty aerosol indispensable component satellite region. solonchaks (salty pans), secondary salinized irrigated lands exposed bottom serve such kind pollution....
Dust/sand storms are common events, and one of the most important manifestations desertification to occur in arid semi-arid regions Middle Asia.Middle Asian deserts characterized by strong winds, scarcity vegetation cover, a continental Mediterranean type climate with long dry summers, lack soil moisture relatively low air moisture, frequent repetition atmospheric droughts, susceptibility soils erosion.Systematic studies dust middle region started 1930s when "black" "white" increased...
Sand seas and dune bedforms are climatic chronicles that have a wide range of scientific meanings. The Karakum Kyzylkum sand in Central Asia span ∼500,000 km 2 , among the largest on Earth; yet, very little is known about their emergence stabilization. Further, internationally accessible literature lacks comprehensive studies interactions between contemporary climate morphodynamics for this region. In study, we applied conventional approach examining wind data—Fryberger’s drift equations...
Hyperspectral remote sensing (RS) and images of various spatial resolution open new vistas for classification mapping trees. These approaches would improve plant in a complex population forest trees diverse species, genera, families, as well monitoring commercial orchards. In this work, we used RS indices cellulose, lignin, wax, chlorophyll, carotenoid, anthocyanin species natural forests For proof concept, the were applied to horticultural crop orchards, where error due mixing different is...
The main causes of desertification in the Aral Sea Basin are regulating flow Amudarya and Syrdarya rivers resulted sharp reduction level, subsequent change regional climate towards aridization continentality, increase irrigation drinking water mineralization, pollution surface ground by municipal wastes residues agrochemicals, deposition salts transferred f?om exposed dried bottom high level water, air soil combination with extreme climatic conditions inevitably affect health women children...
