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.

The trend at scientific Journals is to request/require DOIs be provided with all data products used in submitted articles. For ICON, the DOIs are as follows and should be used when acknowledging data sources in published research. These are noted in the updated ICON Rules of the Road. The URLs link to the SPASE website

A data browser developed by Dr. Yen-Jung Wu here at SSL allows you to make plots of ICON data very quickly, and once the data are plotted provides a quick link to the file at the NASA repository. 

The MIGHTI 2.1 Line-of-Sight winds and 2.2 Cardinal winds have been updated to v4 and are now available out to November 13 2020. The version resolves a disagreement between the green and red winds that became apparent in the June 2020 timeframe, and extends the set.

[by Lina Tran on the NASA blog] On June 22, NASA’s ICON team released scientific data collected during the spacecraft’s first eight months in orbit to the public.

The data release features observations from ICON’s four instruments — MIGHTI, FUV, EUV, and IVM — which have been observing the ins and outs of the ionosphere, the sea of charged particles high in the upper atmosphere. Scientists have been busy parsing the wealth of observations collected by ICON in preparation for the mission’s first science results, which will be released later this year.

“ICON was designed, built, and launched to provide data we had never seen before, and it has not disappointed us in any regard,” said Thomas Immel, ICON principal investigator at University of California, Berkeley. Immel said he was pleased to share ICON’s first data with the world. “The sensitivity and precision of our observations, and the unique orbit and mission design, give us a new and advanced tool for unlocking all the puzzling questions we have had about the connection between Earth’s atmosphere and our space environment.”

The release coincides with the virtual summer meeting of CEDAR, the Coupling, Energetics, and Dynamics of Atmospheric Regions program. The newly released data spans measurements made since the mission’s launch on Oct. 10, 2019. Data can be accessed through University of California Berkeley’s Space Sciences Lab.
