Meteorological dataset for airport fog assessment at Prešov Airport

The primary dataset is a meteorological dataset collected at the Prešov airbase from October 1, 2024, to December 31, 2025. The data were obtained from the Automated Weather Observing System (AWOS) at one-minute intervals. After cleaning and filtering, 583,101 complete records were retained. The dataset includes key parameters influencing fog formation: air temperature, dew point temperature, dew point deficit, wind speed and direction, atmospheric pressure, and visibility. This dataset serves as the main empirical basis for developing and training a neuro-fuzzy model for assessing fog risk in the airport area.
