The Blue Marble 43 Years Later

Here is a side-by-side comparison of views of our planet Earth taken from two different vantage points over more than four decades apart. The iconic "Blue Marble" view on the left was taken 43 years ago on December 7, 1972 from Apollo 17 on its way to the Moon. The view on the right is from Lagrangian Point L1, located approximately one million miles away from earth (about four times farther than the moon) and was provided by the Earth Polychromatic Imaging Camera (EPIC) sensor affixed to the Deep Space Climate Observatory (DSCOVR).

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.
