(a) False composite (bands 5–3–2) of Sentinel-2 (contains modified Copernicus Sentinel data 2019 processed by Sentinel Hub); (b) NDCI (values > 0) for Sentinel-2 at 10 m spatial resolution; (c) for Sentinel-3 at 300 m spatial resolution. Maps are generated by Matlab R2010b (https://es.mathworks.com/help/matlab/release-notes-R2010b.html). S2 scene was downloaded from the Sentinel’s Scientific Data Hub (https://scihub.copernicus.eu/) and processed with ACOLITE 20190326.0 (https://odnature.naturalsciences.be/remsem/software-and-data/acolite). S3 scene was downloaded from the EUMETSAT webpage (https://coda.eumetsat.int).
