Abstract

Chlorophyll fluorescence intensity is affected by the photosynthetic efficiency and the physiological status of plants under various environmental conditions. Chlorophyll fluorescence signals also beneficial to estimate vegetation productivity and vegetation carbon cycling. The use of spaceborne hyperspectral imaging to observe the chlorophyll fluorescence, can greatly increase the observation efficiency, which is conducive to global coverage of fluorescent data. According to the characteristics of space-based remote sensing, the inversion accuracy of chlorophyll fluorescence data depends on the radiation and spectral accuracy of the observing system, which requires high precision ground calibration and on-orbit calibration. Based on the observation elements and the satellite orbit, the on-orbit calibration scheme are proposed, including the field of view, instrument measurement, uncertainty analysis and correction.
