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).


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.

CALIPSO Instrument OFF

Thursday, June 18, 2015

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