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. 

Version 6 of the IVM Level 2 data product is now available on the Public FTP site. It's a significant upgrade, and the release notes in the documentation describe the improvements to the product.

A number of IVM data are reprocessed on days between Feb 7, 2020 and Dec 22, 2021 where conjugate observation periods are present. The long list of these data is noted below. This correctly flags the IVM data mid-manuever to be good. It is recommended that if one is interested in data obtained during these short periods of time that you work with the latest revision of the data where the data quality flag is correct. Watch for timestamps reflecting the reprocessing date in February 2022 and an increase in the revision number over previously available data. Zip files containing these data will be published by Feb 14.
