The progress on thermal infrared surface temperature-and impedance process-based remote sensing dual-source evapotranspiration models was systematically reviewed, and advantages and disadvantages of energy balance models, feature space models, and impedance process-based models were mainly introduced. It is proposed that in the future research of remote sensing evapotranspiration models, we should focus on the combination of physical mechanisms of the two types of dual-source models, strengthen the application of machine learning methods, and enhance the coupling with carbon cycle in impedance process-based evapotranspiration models, so as to further develop remote sensing evapotranspiration models applicable to urban areas.
