This definition allows accounting for elements which are not flat such as needles or stems. LAI is strongly non linearly related to reflectance. Therefore, its estimation from remote sensing observations will be scale dependant over heterogeneous landscapes. When observing a canopy made of different layers of vegetation, it is therefore mandatory to consider all the green layers. This is particularly important for forest canopies where the understory may represent a very significant contribution to the total canopy LAI. The derived LAI corresponds therefore to the total green LAI, including the contribution of the green elements of the understory. The resulting SENTNEL LAI products are relatively consistent with the actual LAI for low LAI values and ‘non-forest’ surfaces; while for forests, particularly for needle leaf types, significant departures with the true LAI are expected. 2020-03-01T00:00:00.00Z series urn:eop:VITO:TERRASCOPE_S2_LAI_V2 eng -84.0 -180.0 84.0 -180.0 84.0 180.0 -84.0 180.0 -84.0 -180.0 (d) the confidentiality of commercial or industrial information, where such confidentiality is provided for by national or community law to protect a legitimate economic interest, including the public interest in maintaining statistical confidentiality and tax secrecy.
