The present study investigates the optical properties of aerosols on daily and seasonal scales with use aerosol depth (AOD) Angström exponent (AE) data retrieved from AErosol RObotic NETwork (AERONET) collected at four stations in Southern Morocco—Saada (31.63° N; 8.16° W), Ouarzazate (30.93° 6.91° Oukaïmeden (31.21° 7.86° W) Ras-El-Aïn (31.67° 7.60° W). An evaluation volumetric size distributi...

Wind power is assessed over Europe, with a special care given to the quantification of intermittency. Using the methodology developed in Gunturu and Schlosser [1], the MERRA boundary flux data was used to compute wind power density profiles over Europe. Besides of the analysis of capacity factor, other metrics have been designed to further quantify the availability and reliability of this resou...

We used a statistical linear model to infer MERRA’s wind speed v t (x ), at time t and on some ECMWF grid point x included in the MERRA grid point x , from MERRA’s estimate v t (x M ): v t (x ) = a E t v M t (x M ) + b E t , where the coefficients a E t and b x t are estimated using ECMWF’s wind speed estimate v E t (x ) as a response variable. This estimation is carried out adaptively on a mon...

Direct Aerosol Radiative Forcing (DARF) characterizes aerosol influences on the radiative energy budget due to scattering and absorption of solar radiation, while clear uncertainties remain in both global regional DARF estimations differences properties time periods considered. Through a multidataset strategy, this study systematically investigates DARFs over Beijing, China, between 2001 2020. ...

Because of the increased temporal and spatial resolutions sensors onboard recently launched satellites, satellite-based surface aerosol concentration, which is usually estimated from optical depth (AOD), expected to become a strategic tool for air quality studies in future. By further exploring relationships concentrations their properties using ground observations, accuracies these products ca...
