Sunglint is the reflection of sunlight off the surface of water that is captured by a detector aboard a satellite. Scientists use sunglint to help detect phenomena such as the seepage of methane gas from the ocean floor and oil slicks on the water surface.

Sunglint in Aqua MODIS images

Sunglint in images captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua Earth observing satellite are slightly to the west of the swath's center line since Aqua crosses the equator in the early afternoon when the sun is west of the sensor.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
