Sentinel-3/FLEX Biophysical Product Confidence Using Sentinel-2 Land-Cover Spatial Distributions
2021
The estimation of biophysical variables from remote sensing data raises important challenges in terms of the acquisition technology and its limitations. In this way, some vegetation parameters, such as chlorophyll fluorescence, require sensors with a high spectral resolution that constrains the spatial resolution while significantly increasing the subpixel land-cover heterogeneity. Precisely, this spatial variability often makes that rather different canopy structures are aggregated together, which eventually generates important deviations in the corresponding parameter quantification. In the context of the Copernicus program (and other related Earth Explorer missions), this article propose…
Caracterización espacial de parámetros biofísicos de la cubierta vegetal para la validación de productos derivados mediante teledetección : aplicació…
2006
El objetivo principal de esta tesis doctoral ha sido el desarrollar una metodología que permita la caracterización espacial a alta resolución de los parámetros biofísicos, LAI, FVC y FAPAR a partir de medidas in-situ, para su uso como verdad-terreno en la validación directa de productos biofísicos. Por otra parte, se ha llevado a cabo la validación indirecta de los productos de baja resolución para toda la Península Ibérica. The main objective of this thesis is to develop a methodology for the validation of coarse resolution satellite products, mainly focused on vegetation products derived using the SEVIRI instrument in the context of the LSA SAF projects.the methodology is based on the cha…
