Sun glint
Sun glint is the mirror-like reflection of the Sun off a water surface in a satellite image.
Data acquired over water will be corrupted by sun-glint contamination. The amount of sun glint is evaluated with the "sun glint normalized reflectance" 
.
Maximum allowed values of sun glint are mission dependent:
- ESA Sentinel-3 mission stated that "Data acquired in the solar channels over water with a sun glint reflectance exceeding 0.0005, assuming a wind speed Ws: threshold 5 m/s, target 7.5 m/s, shall be discarded."
- The NASA PACE mission establishes maximum sun glint normalized reflectance of 0.005 (to be confirmed) for the Ocean Color Instrument (OCI).
- Other missions might look for high sun glint opportunities as a basis of measurement (e.g. NASA OCO-2 mission)
