(SNAP-SL2P) derived LAI with ground observations and to verify consistency of global LAI
products with ground observed LAI and upscaled validated LAI products. In present study,
decametric Sentinel-2 LAI product was retrieved by the SL2P and validated using field
measured LAI. Validated LAI product was upscaled at Copernicus (Sentinel-3/OLCI, PROBA-
V), MODIS (combined terra and aqua) and VIIRS spatial scales for intercomparison with …
