Measurement and evaluation of ambient temperature distribution in Mubi town, Adamawa State, Nigeria (Published)
This paper is based on measurement of ambient (air) temperature distribution in Lamurde, Mubi South local government area, Nigeria. HTC-2 digital LCD thermometer and hygrometer electronic meter manufactured by Shenzhen Oway Technology Co. Limited Guangdong, China was used to collect data in the study area and compared with the National Aeronautics and Space Administrative (NASA) values. The results of the research revealed the maximum air temperature of 29.30oC against 33.70oC (NASA). Instat 3 and Microsoft Excel statistical package were used to analyze the data obtained. The results of T-test revealed p value of 0.0009 which is considered as extremely significant at 95% confidence interval and F-test showed that f (0.08) ≤ F (0.42) which revealed that there is no significant difference between the two data because it has 75% correlation coefficient. The study concluded that the data obtained could be used for research purpose and recommended that other sophisticated equipment should be used to validate the data.

A SHIFT IN INVERSION TEMPERATURE POINTS IN A NON-CONVECTIVE POOL SUBJECTED TO MULTIPLE ABSORBING LAYERS, (Published)
A survey on temperature inversions in a non-convective pool subjected to multiple absorbing layers was conducted in cross River University of Technology, Calabar. Temperature data were generated by monitoring temperature variation with height for four experimental model pools D1,D2,D3 and D0 with one, two,three and zero absorbing layers respectively(transparent glass material of thickness measuring 0.5 cm ), using high mercury in-glass thermometers.The model pools were drums of height measuring 83 cm, perforated at graduated distances inserted with thermometers, and lagged with insulating materials(styropor) of thickness measuring 2.5 cm.The multiple absorbing layers were placed at the top of the drums at interval distances of 10 cm between them.Temperature monitoring was carried out between 6 am and 6 pm for two distinct seasons(dry and wet seasons) on hourly basis, Results obtained from this study showed that a shift in inversion temperature points occurred across the length of the three non-convective pools D1 having at 45.0 cm, D2 at 35.0 cm and D3 at 21.0 cm. The range of inversion temperature was between 0.1oC to 15 oC and occurs at all times of the day with convex(negative) inversion being more prominent.
