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.


MISR L3 Aerosol Optical Depth 2013

Updated MISR Level 3 Imagery tool now contains data for 2009 - 2015. The Level 3 products are derived from averaging select Level 1 and Level 2 parameters over daily, monthly, seasonal and annual time periods. All MISR data products can also be ordered through the MISR Order and Customization Tool.

Toolsets for Airborne Data

The Toolsets for Airborne Data (TAD), developed at the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center (LaRC) to promote the airborne data use, is now available. This beta-release is an intuitive user interface for variable selection across different airborne field studies and includes features to create merge files based on a user’s choice of time base.  Prior to accessing the TAD Web Application (https://tad.larc.nasa.gov) for the first time


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).

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.

CALIPSO Instrument Operational

Friday, October 30, 2015

As of Thursday, Nov. 5, the payload was reported back in data acquisition and back to a nominal data processing state.


Due to a solar event, the CALIPSO satellite payload was commanded to SAFE mode early Thursday Oct. 29, 2015. The payload is expected to be in SAFE mode over the next several days. During this time, no data will be collected nor generated.
