Exploring Where Earth's Weather Meets Space Weather

The Ionospheric Connection Explorer (ICON), the newest addition to NASA’s fleet of Heliophysics satellites, launched on October 10, 2019 at 9:59 p.m. EDT. Led by UC Berkeley, scientists and engineers around the world came together to make ICON a reality.

The goal of the ICON mission is to understand the tug-of-war between Earth’s atmosphere and the space environment. In the "no mans land" of the ionosphere, a continuous struggle between solar forcing and Earth’s weather systems drive extreme and unpredicted variability. ICON will investigate the forces at play in the near-space environment, leading the way in understanding disturbances that can lead to severe interference with communications and GPS signals.

ICON Thermospheric Column O/N2 update - Version 6 and CMAD Draft

Limb and disk retrievals are both available.

Dr. Thomas Immel 0 898

Version 6 of the new limb products is now available on the ICON FTP server and the SPDF website. A draft version of the ICON CMAD is now available on the ICON website that includes detailed descriptions of the O/N2 products, both limb and disk.  Documentation for these products is available through http links (limb and disk) and on the ICON FTP server.

If you are unfamiliar with the Calibration, Measurement, and Algorithms Document, this provides a broad view of the calibration activites and details of the algorithms as they have been updated by the product owners and implemented in the ICON Science Data Center.

This limb product compares well to the disk product that has provided O/N2 for ICON since 2020. When compared, the two retrievals show differences that can be represented by a single offset value, as they co-vary in response to actual changes in O/N2. As with all ICON products, the scientific need is for precision and both of these products meet the mission requirements.

New ICON L2.4 O/N2 Now Available

Colin Triplett 0 143
The FUV O/N2 product (L2.4) for both the Earth’s limb and disk has been updated to version 7 (v07) and is currently available for the full mission on the ICON FTP site and at SPDF. Zipped files on the ICON FTP contain both limb and disk data while they are in separate directories on SPDF. Version 7 incorporates a scattering correction and an update to the uncertainty lower limit estimates. Note version number changed to align both products.  Version 7 is the final version of the FUV O/N2 and should be used for all analysis.
 
These files can be found for the whole of the ICON mission at both the ICON FTP site and SPDF.
 
 
Please read the new documentation for full details of the data.
