Determination of Aerosol Metals Pollutants in Falling Dust in Benghazi City, Libya

Sami H. Almabrok, Mussa M. Ali, Yasmin Y. Mohammed, Eman N. Zew, Badreya R. Hawiel
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...

Spatio-Temporal Patterns of Rainfall Variability for Wet Season over Togo in West Africa

Pouwèréou Nimon, Latifou Issaou, Yawo Konko, Kouami Kokou
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

The Global Solar Radiation in the Southern Region of Ecuador

O. H. Alvarez, T. E. Montano
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

Tragic Aftermath of Californian Jungle Fire and Hawaiian Volcano Outburst, a Warning about Persistently Rising Global Warming, Resulting into High Rated Disaster’s Chain

Malik Muhammad Nazeer
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

Seasonal Variability in Aerosol Microphysical Properties over Selected Rural, Urban and Maritime Sites in Kenya

Geoffrey W. Khamala, Jared O. Odhiambo, John W. Makokha
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

Methane Gas Emissions: Methods of Improving the Efficiency of the Biggest Landfill Gas Waste to Energy Project in the Middle East Installed in Amman, Jordan

Constantine Hadjidimoulas
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 and Sea Surface Temperature Variations over East and West Tropical Pacific Ocean

Yongxin Huang, Biyun Guo, Mantravadi Venkata Subrahmanyam
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

Optical Characterization of Atmospheric Aerosols via Airborne Spectral Imaging and Self-Organizing Map for Climate Change Diagnostics

John W. Makokha, Jared O. Odhiambo
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

Aerosol Optical and Micro-Physical Characteristic Derived from AERONET in Kenya*

Misiani Zachary, Shengjie Niu, Jingjing Lü
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
