DSCOVR and the Blue Marble

This is the Deep Space Climate Observatory (DSCOVR) mission's first view of the entire sunlit side of Earth from 1.6 million kilometers away. It was taken by the Earth Polychromatic Imaging Camera (EPIC), a four-megapixel CCD camera and telescope. The image was taken July 6, 2015, and shows North and Central America. The central turquoise areas are shallow seas around the Caribbean islands. This Earth image shows the effects of sunlight scattered by air molecules, giving the image a characteristic bluish tint.

CATS Instrument

The Cloud-Aerosol Transport System (CATS) is a lidar remote sensing payload utilizing ISS as an affordable Earth Science observing platform. CATS provides in-space demonstration of technologies for future satellite missions while demonstrating build-to-cost project development with streamlined management structure. 

For more information, please see the CATS homepage or the attached presentation (PPT).

DISCOVER-AQ video

Two planes (one from NASA Langley, the other from NASA Wallops), equipped with science instruments, will fly over the San Joaquin valley -- one as close as 1,000 feet to the ground -- to measure air pollution. They are part of a five-year NASA science campaign called DISCOVER-AQ, which is working to improve the ability of satellites to consistently observe air quality in the lowest part of the atmosphere.

Longwave data visualization.

On NASA's Suomi NPP satellite, the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth, helping to assure availability of measurements of the energy leaving the Earth-atmosphere system.  The CERES results help scientists to determine the Earth's energy balance, providing a long-term record of this crucial environmental parameter that will be consistent with those of its predecessors.
