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.

UPDATE: v5 of the temperature product is now on the public site.
