abstract = "Soil sealing in urban areas imposes a large impact on vegetation health and its functioning in providing ecosystem services. Yet, quantitative assessment of soil sealing effect on urban tree health status remains challenging. Here, we investigate the feasibility of using airborne imaging spectroscopy and leaf reflectance for assessing the effect of soil sealing on leaf chlorophyll content of trees and their spectral responses. Results showed that soil sealing decreased the leaf total chlorophyll content and the ratio of carotenoids to chlorophyll. Chlorophyll spectral indices extracted from airborne and leaf reflectance data were both highly correlated with chlorophyll. Spectrally predicted chlorophyll variations allowed for the discrimination of different soil sealing conditions. This study demonstrates the great potential of using airborne remote sensing data to assess the health status of urban vegetation as well as for biomonitoring soil sealing impacts.",
