Characteristic Variation of Ground Heat Flux and Net Radiation at Tropical Station in Ile-Ife,...

The importance of indicated patterns of variability to daily life, as well as the factors that may be responsible for such variations, is enhanced by characteristic variance of ground heat flux and net radiation. This study examines the relationship between ground heat flux and net radiation over a grass-covered surface in Ile-Ife, Nigeria, using field data. An instrumented meteorological mast was set up at an experimental site (7°33'N, 4°35'E) on the Obafemi Awolowo University campus in Ile-Ife, Nigeria, for two weeks of field observations (31st May-14th June, 2013). Soil heat flux, net radiation, and soil temperature are all calculated using the soil heat flux. tools for data processing The results revealed that during the daytime, the measured ground heat flux, HGM, rises until 1400 hrs, with a maximum value of about 136.86 Wm-2 and a minimum value of about -72.87 Wm-2 at 0830 hrs (DOY 156). The maximum value for the entire study duration was estimated net radiation, with a Rn value of 649.65 Wm-2 observed at 1400 hrs (DOY 156). -10.75 Wm-2 Wm-2 Wm-2 Wm-2 Wm-2 Wm Due to the cloudy state of the atmosphere, which decreases the amount of incoming solar radiation reaching the earth surface, the value observed at 1800 hrs (DOY 154) represented the lowest value for the entire duration of the analysis.
