One of the key challenges noted in sustainable development goals for good health and wellbeing (SDGs 3) is both ambient household air pollution. Household solid fuel combustion represents one biggest threat to human South Africa. This study helps understand impact burning an indoor environment. Continuous monitoring particulate matter (PM4) was carried out two houses, used coal as a primary source energy, while other did not. For (SFB) house winter PM4 average 24-h concentration ranges...
This paper reports the observational results of aerosol optical characteristics, modification processes and discrimination key types over Skukuza (24.9°S, 31.5°E, 150 m), a subtropical rural site in South Africa (SA), using CIMEL Sunphotometer data, part AErosol RObotic NETwork (AERONET), from December 2005 to November 2006. The show that pronounced spectral temporal variability properties aerosols is mainly due anthropogenic emissions. different also made daily mean values depth at 500 nm...
Africa's distinctive climate and varied terrain present a crucial domain for examining the intricate relationships between aerosol-cloud-precipitation their implications regional climate, water resources, agriculture. Advances in satellite technology, field research, numerical modeling have propelled progress this field. Satellite instruments facilitated understanding of aerosol properties interplay with clouds precipitation, while ground-based airborne measurements from initiatives like...
In this study, we have used the Terra satellite onboard of Moderate Resolution Imaging Spectroradiometer (MODIS) to investigate spatial and temporal relationship between aerosol optical depth (AOD) cloud parameters namely, water vapor (WV), (COD), fraction (CF), effective radius (CER), top pressure (CTP), temperature (CTT) based on 10 years (from January 2004 December 2013) dataset over six locations in South Africa (SA). The obtained results indicated seasonal variation AOD, with high...
High concentrations of the ambient particulate matter remains a concern on South African Highveld, particularly in densely populated low-income settlements. These areas have several local emission sources that contribute to poor air quality and are often located close industrial other urban areas. The vary magnitude, space, time. In Africa, little has been done assess impacts spatiotemporal variability credibility using isolated observations for regulatory purposes. This study aims evaluate...
The World health organization (WHO) is particularly concerned about the ambient concentrations of Particulate Matter (PM10, PM2.5), Sulfur dioxide (SO2), Nitrogen (NO2), and Ozone (O3). This paper investigates contributions both coal-fired plants coal-burning households to these critical pollutants. Using twelve months’ data, annual pollutants were 60, 34, 39, 14, 64 μg/m3 respectively with PM10, PM2.5 exceeding National Ambient Air Quality Standard (NAAQS). diurnal pattern PM10 have double...
Atmospheric aerosols contribute significantly to the uncertainty in radiative forcing effects that influence climate and pose a significant health risk humans. The climatic implications of are dependent on many variables, including aerosol size, shape, chemical composition, position atmospheric column. impact transported over west coast southern Africa has been found, particular, be complicated by aforementioned properties. This study investigated columnar optical properties Gobabeb, Namibia...
This article reports the results obtained from sun-sky radiometer over a subtropical urban station Pretoria, South Africa January to December, 2012. Detailed analysis revealed that, monthly mean AOD <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">500</sub> ranges 0.10 0.34 with an annual of 0.19±0.09. The aerosol volume size distribution has shown bimodal log-normal structure fine (coarse) mode maximum at radius 0.15 μm (5.0 μm). SSA showed...

ABSTRACT Background Sometimes in 2019, there was an outbreak of coronavirus pandemic. Data shows that the virus has infected millions people and claimed thousands lives. Vaccination other non-pharmacological interventions have brought a relief; however, COVID-19 left some indelible marks. This work focuses on time series analysis prediction fatality rates Black community. Decision makers will find useful building robust architecture for resilient pandemic preparedness responsiveness against...

&lt;p&gt;Ambient air pollution is a leading cause of premature mortality across the world, with an estimated 258,000 deaths in Africa (UNICEF/GBD 2017). These impacts have large uncertainties as many major cities do not any ground-based quality monitoring. The lack data due part to high cost traditional monitoring equipment and trained personnel. As &amp;#8220;Make Air Quality Great Again&amp;#8221; project under Our Planet framework (MOPGA), we propose filling this gap...
