description The invention relates to a horizontal visibility forecast method based on site measured data and model results. The invention adopts the specific technical scheme that a horizontal visibility algorithm is established on the basis of the site measured data, and the horizontal visibility forecast is realized in combination with the model results; the data is hourly observed by utilizing an automaticweather station, an algorithm for calculating horizontal visibility (level) by basic meteorological factors such as temperature and relative humidity at each site is established through a neural network method, one-to-one correspondence is established through considering the geographic information of sites and pattern grid points, the site measured data and the model forecast data within a period of time are selected, and a model for correcting from each of the grid points to the corresponding measured site is obtained by calculation; when forecast is required, firstly the model forecast data within the time to-be-fo
