Gauge data from a West African network of 920 stations are used to assess Tropical Rainfall Measuring Mission (TRMM) satellite and blended rainfall products for 1998. In this study, mean fields, scattergrams, latitudinal transects the months May–September 5-month season presented. Error statistics also calculated. This study demonstrates that both TRMM-adjusted Geostationary Observational Environmental Satellite precipitation index (AGPI) TRMM-merged show excellent agreement with gauge over...
Gauge data over North Africa are used to provide an assessment of satellite and blended rainfall products for 1988–94 1998. A comparison is also made with the Global Precipitation Climatology Center (GPCC) gauge dataset. For period, mean fields latitudinal transects June–July–August season presented, based on a 515-station dataset, GPCC data, Project (GPCP) infrared-based Geostationary Operational Environmental Satellite precipitation index (GPI), Special Sensor Microwave Imager (SSM/I)...
The first episodes of floods caused by heavy rainfall during the major rainy season in 2018 occurred Accra (5.6°N and 0.17°W), a coastal town, Kumasi (6.72°N 1.6°W) forest region on 18th 28th June, respectively. We applied Weather Research Forecasting (WRF) model to investigate examine meteorological dynamics, which resulted extreme that 14 deaths, 34076 people being displaced with damaged properties, economic loss estimated at $168,289 for two cities according National Disaster Management...
Abstract Periodic climate zoning is an essential classification of land cover to account for anthropogenic activities resulting from population increase and urbanization that affect key response parameters. Rainfall, relative humidity (RH), maximum (T max ) minimum temperature min data the Ghana Meteorological Agency were used zone by adopting cluster PCA analysis methods verifying groupings with seasonal trend Tukey Honestly Significance Difference (HSD) analysis. The grouped synoptic...
Estimates of global horizontal irradiance (GHI) from reanalysis and satellite-based data are the most important information for design monitoring PV systems in Africa, but their quality is unknown due to lack situ measurements. In this study, we evaluate performance hourly GHI state-of-the-art products (ERA5, CAMS, MERRA-2, SARAH-2) with 37 quality-controlled measurements novel meteorological networks established Burkina Faso Ghana under different weather conditions year 2020. The effects...
The increasing demand of Ghana's renewable energy sector requires a comprehensive evaluation sky conditions that may be favourable for the efficient harnessing solar resources. However, data such are typically scarce due to instrumentation challenges. Empirical estimates using sunshine duration and cloud cover as input were used evaluate resources' potential at 22 synoptic stations distributed across four climatic zones Ghana (savannah, transition, forest coastal) period 2015 – 2018....
Ghana is located in west Africa by the coast with majority of annual rainfall coming from African monsoon. Thanks to a new dense, long-term dataset spatial structure for different phases monsoon has been investigated. Previous studies have only considered general decorrelation range whereas this study novel approach estimating rate depending on intensity event implemented. The anisotropic pattern at subweekly and local scale was also modelled. correlation varies greatly phase monsoon, much...
E-commerce has been used in many business transactions because of its practicality and easiness for the users. In addition, it also provides control. The use electronic money (e-money) as a non-cash payment alternative huge potential decreasing cash money. E-money faster more comfortable compared to money, especially small-amount transactions. With e-money, every transaction is simpler, cheaper, easier both buyers sellers. One government interventions recently that highway can only be paid...
Estimates of global horizontal irradiance (GHI) from reanalysis and satellite-based data are the most important information for design monitoring PV systems in Africa, but their quality is unknown due to lack situ measurements. In this study, we evaluate performance hourly GHI state-of-the-art products (ERA5, CAMS, MERRA-2 SARAH -2) with 51 quality-controlled measurements novel meteorological networks established Burkina Faso Ghana under different weather conditions. The effects clouds...
<p>Global horizontal irradiance (GHI) is the primary driver for photovoltaic (PV) technology. For PV system design and monitoring, hourly sub-hourly GHI from reanalysis satellite-based data are frequently used, especially in data-poor regions like Sub-Saharan Africa. However, use of these datasets uncertain need to be assessed detail. In this study, we evaluated performance state-of-the-art (ERA5, CAMS, MERRA-2 SARAH-2) with situ measurements main climatic zones (Guinea,...
<p>The spatial structure of rainfall events over west Africa is not very well understood, and a major limitation for improving this understanding the generally sparse rain gauge network. This lack knowledge makes it difficult to describe state between gauges, something that important if one wants determine which locations are likely have received not. Earlier work on estimating correlation structures has been limited by long distances often longer than actual...
