The key to improving the ability of independent innovation lies in talents and education. In order to cultivate high-quality innovative talents in the field of “quantitative remote sensing”, this summer course held an academic salon for graduate students in combination with the frontier issues of quantitative remote sensing that the trainees were concerned about. The academic salon held four academic salons aiming at the academic problems in the theory, method, technology and application of quantitative remote sensing. The mechanism of radiation transfer, the decomposition of hyperspectral remote sensing mixed pixels, the application and service of UAV quantitative remote sensing were discussed. Among them, the academic salon of “radiation transfer mechanism” mainly discussed the progress and limitations of radiation transfer theory from Maxwell’s equations to microcosmic physics. “Hyperspectral remote sensing mixed pixel decomposition” academic salon mainly focused on two aspects of endmember variability research, namely, the discussion of spectral variability within the same endmember category and the spectral similarity between different endmember categories. Participants deeply discussed the theory and method of how to eliminate the unmixing error of hyperspectral remote sensing mixed pixel. The “vegetation fluorescence remote sensing” academic salon mainly discussed the application progress of solar-induced chlorophyll fluorescence (SIF) remote sensing, the process and mechanism of SIF excitation from leaf to sensor and its mechanism. Participants discussed five main issues in depth. “UAV quantitative remote sensing application and service” academic salon focused on UAV quantitative remote sensing and multi aircraft cooperative networking earth observation and remote sensing application service in complex scenes. Participants believed that UAV quantitative remote sensing application and service has broad prospects in the future. In each academic salon, a graduate student made a keynote speech. The participants would apply for a speech around the topic, discuss and question, and elaborate personal views or supplement relevant research progress information on relevant progress. The host would make a summary speech. The online academic salon provided a new academic platform for graduate students to exchange and discuss the frontier progress of quantitative remote sensing. The academic salon attracted many interested graduate students and other personnel to participate through live broadcast of bilibili station, and expanded the dissemination of quantitative remote sensing knowledge.
