This work studied the comparative analysis of meteorological parameter (temperature, solar radiation and relative humidity) of satellite and Nigerian Meteorological Agency (NIMET) data at Kano, Kaduna, Owerri and Sokoto for 2006, 2007, 2008, and 2010, respectively. Statistical tools of mean bias error (MBE), root mean square error (RMSE) and correlation coefficient (r) were determined to validate the data. The results revealed that NIMET and Satellite data have similar signatures. This implies that either of the data could be used for the same purpose in Nigeria. The low RMSE and MBE values confirmed that satellite-based data could be used in Nigeria where equipment is not available to take measurement. The results also showed that the correlation coefficients (r) between NIMET and satellite data range from 0.70 to 0.97. This also suggests that about 70% and above correlation occurred between the data, which imply strong correlations. The correlation suggests close relationship between NIMET and satellite data.
