ICON is in process of approving the Hough Mode product, the first Level 4 product, available for most of 2020. This product comes in 2 parts; 1) a set of diurnal and semidiurnal tidal amplitudes in a sliding 30-day window for 2020 centered on the day of interest, and 2) a TIEGCM lower boundary specification for the same date.

Update: These files are now all available on the public ftp site

Documentation for each of these components (1, 2) of the product are also available on the FTP site.

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.
