New IVM Level 2 data (Version 4 of Product 2.7) is now available. This update extends the dataset to the end of 2020 and provide a correction for observed bias in all three velocity components. We recommend that users migrate to these products as soon as they are available. The largest correction is to ram velocities.

The version 3 Level 1IVM data are already approved and available on the FTP site.

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.

There is an update coming for MIGHTI 2.3 temperatures, bringing the product up to version 4. The change primarily affects nighttime temperature retrievals. Details are available in the history attribute in the NetCDF, and also in the online documentation, given in the link below. An update to the FTP site organization is also reported below. - UPDATED New FTP links below

Two weeks ago, ICON passed a major review at NASA Headquarters, putting it on schedule to launch in ten months. It's a big milestone. ICON was approved to proceed with observatory integration at Orbital ATK in Virginia, meaning that the payload with all the attached instruments was mated to the spacecraft bus, a significant step in the journey to becoming a real science observatory.

Earth’s ionosphere is chemically and dynamically complex—energized and stirred up by the aurora at the poles, concentrated and unstable at the equator. ICON focuses on this region because it is the place where coupling between our atmosphere and our space environment really occurs.  Our understanding of this relationship has come from almost a century of measurements, first from the ground and later from space.
