The aim of this study is to determine the concentrations of selected aerosol metals in falling dust at different roadsides in Benghazi city. In order to do that, Flame atomic absorption spectroscopy (FAAS) technique has used to quantitative the areoles metals. Six composite samples were collected along roadsides in Benghazi city and each composite sample was represented average of five samples. The concentrations of aerosol metals of each site were based on density of traffic road, type of indus...

Climate change is affecting rainfall variability. This paper investigated the June-September (JJAS) rainfall variability using reanalyzed and observed da-tasets from 1976 to 2015 in Togo. The rotated empirical orthogonal function (REOF) method was used to get the distribution patterns of JJAS rainfall. The Mann-Kendall (MK) statistic was also used to detect temporal trend of the ro-tated principal component time series (RPCs) that ...

In this work an approach to the theoretical solar radiation in the South Region of Ecuador is presented, using the Hottel Model ([1] [2]), considering the cloudiness and the topography Shadows. The maps of Global Solar Radiation are shown for the months of January, August and Annual one, considering the heights over the middle sea level extracted of the Digital Elevation Model. This work will ...

Earthglobe is almost at flash point with respect to global heat contents and temperature and any sizeable further addition of heat to its environment will result into huge disaster of life, property and infrastructure at multiple locations on the globe. The recent example of this is the aftermath of Cali-fornian forest fires (2017-2018) and Hawaii volcano eruption as elaborated in this treatise. This has resulted into 7 main catas ...

Atmospheric aerosols are posing a great threat to the already stressed climate with the effects being felt more on African continent. Their presence and interaction with the clouds contribute to the strongest uncertainty in aerosol characteristics and Earth’s energy budget hence; calling for a long term assessment to be done. The present study analyses long term spatiotemporal microphysical aerosol characteristics (namely: effecti ...

In a world of increasing population and consumption, there is a pressing need to use our resources in the best possible way. This involves reducing the generation of waste, achieving high-quality recycling and efficient use of the residual waste for highly productive clean energy generation. A waste-to-energy facility may generate a range of energy outputs such as electricity, district heating, steam for industrial processes and m ...

Shortwave radiation (SWR) is having direct impact on
sea surface temperature (SST). In this paper the relation between SWR and SST
has been over east and west Pacific Ocean. TAO/TRITON buoy data have been used for this study. It is well known that El
Nino phenomenon is related to SST anomalies and warmer temperatures can observe
over eastern Pacific Ocean (EP) leading to strong El Nino. The relation between
eastern and western Pac ...

Self-Organizing
Map (SOM) analysis is used to perform optical characteri- zation of both Aerosol Optical Depth (AOD) and
Angstrom Exponent (AE) retrieved from Moderate-resolution
Imaging Spectroradiometer (MODIS) in relation to Precipitation Rate (PR)
from Tropical Rainfall Measurement Mission (TRMM) over selected East African
sites from 2000 to 2014 and further diagnose climate change over the region if
any. SOM reveals a marked ...

The identification and classicization of both
natural and anthropogenic atmospheric aerosols originating from different
region is becoming very useful when dealing with effect of air quality.
Different areas may encounter the problem of dust storm events which is
harmfully to the environment and human health. This thesis works focused mainly
on the evaluation of level 1.5 data from Sunphotometer remote sensing to
understa ...
