The study aims to validate the LAI product derived from Sentinel-2 Level 2 Prototype Processor (SNAP-SL2P) and compare it with ground observations and other global LAI products for consistency.
The main objective of the study was to validate the Sentinel-2 Level 2 Prototype Processor (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 ground observed LAI and global LAI products, was presented as a way forward to validate hectometric LAI products.
