A Trend Analysis of Temperature in Selected Stations in Nigeria Using Three Different Approaches

Dakéga Saberma Ragatoa, Kehinde Olufunso Ogunjobi, Appollonia Aimiosino Okhimamhe, Sabastine Dekaa Francis, Lucette Adet
This study used daily observation data obtained from the Nigerian Meteorological Agency (NiMet) to investigate the temperature trend of Nigeria from 1981-2015. The data were homogenised using the Quantile Matching (QM) method and Quality Controlled. The data have been transformed into three sets of data with different periods: daily, monthly and yearly. The datasets (daily, monthly and yearly) were checked for autocorrelation and
