Data correction method, device and equipment, and medium

The embodiment of the invention discloses a data correction method, device and equipment, and a medium. The method comprises the following steps: acquiring historical forecast data and real-time forecast data of a plurality of meteorological elements of a target station, and historical observation data of elements to be corrected of the target station; determining a correlation coefficient between each meteorological element and a to-be-corrected element according to the historical forecast data and the historical observation data; according to the correlation coefficient, screening out meteorological factors of which the correlation coefficient conforms to a preset threshold range; performing dimension reduction processing on the screened historical forecast data and real-time forecast data of the meteorological elements to obtain a minimum meteorological element feature set containing at least one meteorological element feature; and determining real-time forecast data of the to-be-corrected element accordin
