NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission is being developed. Its most important feature is the state-of-the-art Ocean Color Instrument (OCI).
The OCI will measure light over a broader spectrum than today's ocean color instruments.
What does that mean?
The OCI will cover the full range of wavelengths in the Visible Spectrum. It will also see shorter Ultraviolet wavelengths along with some Infrared bands.
In addition, PACE will measure light at finer resolution than ever before. This will revolutionize our ability to distinguish important details in the ocean and atmosphere.
Some of today's ocean color instruments collect data at only five visible wavelengths.
