The Dynamics of ERA5 and GNSS-Derived Precipitable Water Vapour in the Climatic Zones of Nigeria
Ojegbile, B.M., Okolie, C.J., Omogunloye, O.G., Abiodun, O.E. and Olaleye, J.B.
The global state-of-art ERA5 reanalysis dataset which records the total column of water vapour (i.e., precipitable water vapour) has gained wide popularity among climate researchers. Its peculiar variation in Nigeria’s climatic regions has been addressed in this study. The GNSS-derived PWV has been underscored to have a higher spatio-temporal and all-weather accuracy in all the climatic regions of the country...... [more]
