Abstract. The Ångström exponent, α, is often used as a qualitative indicator of aerosol particle size. In this study, optical depth (AOD) and exponent (α) data were analyzed to obtain information about the adequacy simple use for characterizing aerosols, exploring possibilities more efficient characterization aerosols. This was made possible by taking advantage spectral variation so-called curvature. taken from four selected AERONET stations, which are representative types, i.e. biomass...
Abstract. Aerosols have a significant regional and global effect on climate, which is about equal in magnitude but opposite sign to that of greenhouse gases. Nevertheless, the aerosol climatic changes strongly with space time because large variability physical optical properties, due variety their sources, are natural, anthropogenic, dependence prevailing meteorological atmospheric conditions. Characterization properties major importance for assessment role climate. In present study, 3-year...
Natural and anthropogenic aerosols over northern India play an important role in influencing the regional radiation budget, causing climate implications to overall hydrological cycle of South Asia. In context change air quality, we discuss aerosol loading variability trends at Kanpur AERONET station located central part Indo-Gangetic plains (IGP), during last decade (2001–10). Ground-based radiometric measurements show increase column-integrated optical depth (AOD) on a yearly basis. This...
Abstract. This study assesses the impact of dust on surface solar radiation focussing an extreme event. For this purpose, we exploited synergy AERONET measurements and passive active satellite remote sensing (MODIS CALIPSO) observations, in conjunction with radiative transfer model (RTM) chemical transport (CTM) simulations 1-day forecasts from Copernicus Atmosphere Monitoring Service (CAMS). The area interest is eastern Mediterranean where anomalously high aerosol loads were recorded...
In late March 2018, a large part of the Eastern Mediterranean experienced an extraordinary episode African dust, one most intense in recent years, here referred to as "Minoan Red" event. The mainly affected Greek island Crete, where highest aerosol concentrations over past 15 yeas were recorded, although impacts also felt well beyond this core area. Our study fills gap dust research by assessing multi-sectoral sand and storms their socioeconomic implications. Specifically, we provide impact...
A discrimination of the different aerosol types over Arabian Sea (AS) during Integrated Campaign for Aerosols, Gases and Radiation Budget (ICARB‐06) is made using values optical depth (AOD) at 500 nm (AOD ) Ångström exponent ( α in spectral band 340–1020 ). For this purpose, appropriate thresholds AOD are applied. It shown that a single type given location AS can exist only under specific conditions while presence mixed aerosols usual situation. Analysis indicates dominant change...
This study estimates the impact of dust aerosols on surface solar radiation and energy in Egypt based Earth Observation (EO) related techniques. For this purpose, we exploited synergy monthly mean daily post processed satellite remote sensing observations from MODerate resolution Imaging Spectroradiometer (MODIS), radiative transfer model (RTM) simulations utilizing machine learning, conjunction with 1-day forecasts Copernicus Atmosphere Monitoring Service (CAMS). As cloudy conditions region...
Abstract. This study focuses on the assessment of surface solar radiation (SSR) based operational neural network (NN) and multi-regression function (MRF) modelling techniques that produce instantaneous (in less than 1 min) outputs. Using real-time cloud aerosol optical properties inputs from Spinning Enhanced Visible Infrared Imager (SEVIRI) board Meteosat Second Generation (MSG) satellite Copernicus Atmosphere Monitoring Service (CAMS), respectively, these models are capable calculating SSR...
The sun is an abundant source of energy, and solar energy has been at the forefront renewable sector for years. A way to convert it into electricity by use cells. Multiple cells, connected each other, create panels, which in their turn, are a string, they farms. These structures extremely efficient production, but also, cells fragile nature delicate environmental conditions, reason why some them show discrepancies called defective. In this research, thermal camera mounted on drone used first...
A synergy of satellite and ground‐based radiometric observations, along with chemical transport modeling, was used for the assessment influence drought monsoon conditions 2002 prolonged dry pre‐monsoon period 2003 on aerosol properties over south Asia, emphasis northern India. Reanalysis data are also examined studying anomalous from climatological mean, that show prevalence westerlies under anticyclonic circulation subsidence favoring accumulation aerosols. TRMM observations Asia indicate...
Abstract. Ship-borne sunphotometer measurements obtained in the Arabian Sea (AS) pre-monsoon season (18 April–10 May 2006) during a cruise campaign (ICARB) have been used to retrieve Aerosol Optical Depth (AOD; τ) and Ångström wavelength exponent (α). The continents surrounding AS produce natural anthropogenic aerosols that distinctive influences on α its spectral distribution. values were estimated by means of least-squares method over bands 340–1020 nm 340–870 nm. distribution AOD...
The direct radiative effects of atmospheric aerosols are essential for climate, as well other societal areas, such the energy sector. goal present study is to exploit newly developed ModIs Dust AeroSol (MIDAS) dataset quantifying on downwelling surface solar irradiance (DSSI), induced by total and dust aerosol amounts, under clear-sky conditions associated impacts broader Mediterranean Basin, over period 2003–2017. Aerosol optical depth (AOD) (DOD) derived MIDAS dataset, along with...
