Glitter helps to monitor ocean waves
20 March 2017
The notion of glitter might appear as somewhat frivolous, but scientists are using Sun glitter in images from the Copernicus Sentinel-2 mission to map the motion of the sea surface.
Created by wind blowing across the surface, wave patterns are complex and highly varied. Being able to predict their movement can greatly benefit mariners, port and rig builders, coastal farmers and more.
Since measurements of waves from buoys and ships are limited in numbers and in coverage, satellites provide the answer over the oceans. As well as the well-established use of measurements of roughness from satellite sensors, Sentinel-2's multispectral camera can also have an important role to play in mapping ocean waves.

Launched on 13 October, the Sentinel-5P satellite has delivered its first images of air pollution.
Even though the satellite is still being prepared for service, these first results have been hailed as exceptional and show how this latest Copernicus satellite is set to take the task of monitoring air quality into a new era.
