Mission Operations Update #6 - New Temperature Retrievals

MIGHTI 2.3 product up to Version 5

Dr. Thomas Immel 0 108

An update to the ICON MIGHTI 2.3 product for MLT temperatures is coming shortly to the public FTP site. It includes a number of changes related to the flat field of the instrument when making O2 A-band measurements at 5 different wavelengths. This extends the range of altitudes and solar zenith angles of available temperatures from both MIGHTI A and B, and reduces the differences in results from the two channels. Please see the Documentation online for details of this product update.

Mission Operations Update #5 - New Nighttime FUV O+ retrievals

Dr. Thomas Immel 0 352

The ICON FUV 2.5 product for nighttime O+ profiles is updated to version 4 and available now in the public FTP archive. This product now contains a data quality flag indicating the possibility of additional radiance in the scene due to precipitation of conjugate photo electrons. This is further described in the product documentation, available on the Data page of this site.

Mission Operations Update #4 - New IVM L1 and L2 data now available

Dr. Thomas Immel 0 507

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.
