Image sequence from upper left to lower right:
- View from top of the atmosphere.
- Effect of scattering from gases – which makes the sky look blue – has been removed.
- Aerosols have been partially cleared away to reveal more ocean features.
- Adjusted image showing regions with higher chlorophyll (green pigment found in phytoplankton) brightened, haze darkened, and data stripes reduced. (Note that PACE's OCI is being designed to minimize data striping.)
How will PACE aid in our understanding of the ocean and atmosphere?
In addition to detecting the full visible spectrum, the OCI will sense shorter (Ultraviolet) and longer (Infrared) wavelengths. With the OCI and polarimeters, PACE will measure an exceptionally broad range of wavelengths to reveal new details about our ocean and atmosphere.
PACE's fine-resolution measurements over a broad spectrum of light is known as hyperspectral imaging.
Scheduled to launch in 2022, PACE will extend and improve NASA's over 20-year record of observing ocean life, aerosols, and clouds.
We need to monitor Earth's ocean-aerosol-cloud system with ever-improving technologies. That's clearly the best way to go.
More Wavelengths. Better Resolution.
