This paper summarizes recent progress in the observation,mechanism,and modeling of land-atmosphere interactions,and demonstrates that existing observational studies have not considered the effects of changes in terrestrial ecophysiology and the atmospheric boundary layer on land-atmosphere fluxes.Consequently,they restrict the parameterization of land surface processes,parameter inversion from satellite remote sensing,and the operational application of the land surface process model.To gain a comprehensive understanding of land-atmosphere interactions and the development of land surface process models,studies on the effects of changes in terrestrial ecophysiology and atmospheric boundary layers on land-atmosphere interactions and the operational application of land-surface process models need to be emphasized in the future.The main tasks to be considered include:① three-dimensional observation of the land-atmosphere interactions across the boundary layer,② application of multi-source data in the land-atmosphere interactions across the boundary layer,and ③development and operational application of land surface process models.
