Spectral Bands

Reference table for multi-spectral satellite bands. Understand wavelength ranges, spatial resolutions, and primary applications for Sentinel-2 MSI.

Band	Wavelength	Resolution	Sensor	Applications

B04 — Red	665 nm	10 m	Sentinel-2	Chlorophyll absorption, NDVI computation
B05 — Red Edge 1	705 nm	20 m	Sentinel-2	Vegetation stress, leaf area index
B06 — Red Edge 2	740 nm	20 m	Sentinel-2	Canopy chlorophyll content
B07 — Red Edge 3	783 nm	20 m	Sentinel-2	Leaf area index, biomass
B08 — NIR	842 nm	10 m	Sentinel-2	Vegetation indices (NDVI, EVI), land/water discrimination
B8A — Narrow NIR	865 nm	20 m	Sentinel-2	Water vapour correction, refined vegetation indices
B09 — Water Vapour	945 nm	60 m	Sentinel-2	Atmospheric water vapour estimation
B10 — Cirrus	1375 nm	60 m	Sentinel-2	Cirrus cloud detection (L1C only)

Working towards it: Landsat OLI/TIRS and MODIS band reference tables are being added. Hyperspectral band documentation (PRISMA, EnMAP) is planned for a future release.
