Sentinel2 L1C cloud-free composites (2015-2017, 2018, 2019 and 2020)
Sentinel-2 L1C cloud-free pan-tropical annual composites for the period 2015-2017,
2018, 2019 and 2020 are compute by extracting per-band annual median values after cloud and shadow masking
based on spectral conditions specifically developed for tropical regions as proposed by Simonetti D. et al., 2021.
All available Sentinel-2 images have been processed in Google Earth Engine (GEE) and downloaded by selecting only
TOA-Reflectance B11, B08, B04 (SWIR1, NIR, RED) bands at a spatial resolution of 20m (10m bands are resampled to
20m using nearest neighbour approach) and converted to 8bit (Byte) using a multiplicative factor of 0.051 for
visualization purposes and size optimization.
