Abstract: The present application discloses an anthropogenic heat flux estimation method and system based on flux observation data. The method includes: performing grid division on the selected region, and acquiring building vector data, land utilization data and instrument observation data in the selected region; calculating and correcting sensible heat fluxes and latent heat fluxes of different underlying surface types in a vorticity correlator flux source region; calculating temporal-spatial distribution of the sensible heat flux and the latent heat flux of each grid in a large-aperture scintillometer flux source region, and calculating temporal-spatial distribution of an anthropogenic heat flux of each grid in the flux source region in combination with a surface energy balance equation; and constructing an anthropogenic heat flux estimation model based on a convolutional neural network, and accurately estimating temporal-spatial distribution of the anthropogenic heat flux of each grid in the selected region.
