Description:
Sentinel-2 provides high-resolution optical imagery for land monitoring, vegetation analysis, water bodies, and disaster response, with a focus on agriculture and environmental monitoring.
Variable(s):
Sentinel-2 has 13 spectral bands: B1 (Coastal Aerosol - 443nm), B2 (Blue - 490nm), B3 (Green - 560nm), B4 (Red - 665nm), B5 (Red Edge 1 - 705nm), B6 (Red Edge 2 - 740nm), B7 (Red Edge 3 - 783nm), B8 (NIR - 842nm), B8A (Narrow NIR - 865nm), B9 (Water Vapor - 945nm), B10 (SWIR-Cirrus - 1375nm), B11 (SWIR 1 - 1610nm), B12 (SWIR 2 - 2190nm).
Spatial coverage:
Spatial resolution:
10m (RGB, NIR), 20m (Red Edge, SWIR), 60m (Coastal aerosol, Water vapor)
Temporal coverage:
2015–Present (Sentinel-2A launched in 2015, 2B in 2017)
Temporal resolution:
5 days (combined 2A & 2B), 10 days (single satellite)

API Protocol:
The Copernicus Data Space Ecosystem catalogue is a web service that can be queried through 4 REST protocols - OData - STAC - OpenSearch - Sentinel Hub Catalog API
Limitations:
Cloud cover can affect optical data; preprocessing needed for atmospheric correction; large datasets require storage and processing capacity
