Comparison between experimental and satellite temperature datasets in Covenant University

Area of Science:

• Meteorology
• Atmospheric Science
• Remote Sensing

Background:

• Accurate meteorological data is crucial for understanding atmospheric conditions and their effects.
• Satellite remote sensing offers a valuable tool for acquiring large-scale atmospheric data.
• Ground-based weather stations provide localized, high-resolution meteorological measurements.

Purpose of the Study:

• To assess and evaluate clear-sky temperature data collected over five years (2012-2016) in Covenant University, Ota, Ogun State, Nigeria.
• To compare meteorological data obtained from ground-based measurements with satellite-derived data.
• To determine the temporal patterns of peak temperature events in the study area.

Main Methods:

• Acquisition of ground meteorological data using a Davis weather station data logger-vantage pro2.
• Obtaining satellite data from the Atmospheric Infrared Sounder (AIRS).
• Utilizing descriptive statistics to assess and evaluate the agreement between ground and satellite data sets for the same geographical location (Lat: 6.67°N, Long: 3.23°E).

Main Results:

• A perfect agreement was found between the ground-based meteorological data and the Atmospheric Infrared Sounder (AIRS) satellite data.
• Peak temperature events were consistently observed between November and April over the five-year observation period.
• The data sets were validated through descriptive statistical analysis.

Conclusions:

• The study confirms the reliability of both ground-based and AIRS satellite data for monitoring clear-sky temperature events in the study region.
• The identified seasonal pattern of peak temperatures provides valuable insights for meteorological studies in Nigeria.
• The validated data can support further research on non-rainy attenuation effects in the area.
