Time Series Analysis Of Solar Radiation At Onne Port Harcourt, Rivers State
ABSTRACT
This
study analyzed a time series data on solar radiation. The data for this
analysis was international Institute of Tropical Agriculture (IlTA), Humid
Forest Station, Onne Port Harcourt, Rivers State and covered the period 1996---
1997. The ultimate objective of this study was to construct a mathematical model,
which could be used to forecast a reliable and relevant future solar radiation
pattern for Onne Port Harcourt. Simple descriptive time series analysis was used
to estimate and consequently isolate the components (trend, seasonal, cyclical
and irregular) of the time series data based on the original data. The analysis
showed that the trend was constait and so it was estimated using the overall
mean. Seasonal variations were found to be present in the data. This seasonal variation
were estimated and isolated leaving behind the residuals. Forecasts of future
solar radiation pattern were made using the estimates of the trend and seasonal
variations. It is recommended that data for prolonged period say twenty years
be used a probability model be fitted to the data for better forecast.
