Comparison between experimental and satellite temperature datasets in Covenant University.

This article contains the ground and satellite meteorological data sets of clear-sky temperature events for five years (2012-2016) in Covenant University, Ota, Ogun State, Nigeria. The satellite data were obtained from Atmospheric Infrared Sounder (AIRS) while the ground data information were acquired from Davis weather station data logger-vantage pro2. These data were acquired from propagation study that used same location (Lat: 6.67°N and Long: 3.23°E) for both satellite data and radiometer directed along the same path by providing information about the temperature. The data sets were assessed and evaluated by means of a descriptive statistics. There was perfect agreement between the two data. The peak temperature events occurs between the months of November and April for the five years of observation for both Ota and AIRS Satellite. The data from this article can be used for further studies on non-rainy attenuation effect in the study area.

Value of the data

The data could be used to estimate clear-air attenuation in troposphere.

The technique employed here can be replicated on temperature across Nigeria.

The information provided in this data can be used for purpose of citing antenna during rainy season and non-rainy season.

This data may be appreciated in understanding tropospheric scintillation and gas attenuation.

Ground and satellite temperature data

Both the ground measured data and satellite data for this article were collected from Davis weather station data logger-vantage pro2 located at the top roof of College of Science and Technology of Covenant University, Nigeria and Atmospheric Infrared Sounder (AIRS) for five years between January 2012 and December 2016 respectively. The data major input parameter is temperature as presented in Table 1, Table 2, Table 3, Table 4, Table 5. The ground temperature data gathered were arranged on daily average data that is based on one-minute data and consequently used to achieve the monthly data. The monthly averages of both experimental and satellite data five years is a good description of the seasonal performance of temperature as shown in Table 1, Table 2, Table 3, Table 4, Table 5. The statistical descriptive analyses were additional carried out on the data sets for more investigation.
