New ICON L2.4 O/N2 Now Available

Colin Triplett 0 47
The FUV O/N2 product (L2.4) for both the Earth’s limb and disk has been updated to version 7 (v07) and is currently available for the full mission on the ICON FTP site and at SPDF. Zipped files on the ICON FTP contain both limb and disk data while they are in separate directories on SPDF. Version 7 incorporates a scattering correction and an update to the uncertainty lower limit estimates. Note version number changed to align both products.  Version 7 is the final version of the FUV O/N2 and should be used for all analysis.
 
These files can be found for the whole of the ICON mission at both the ICON FTP site and SPDF.

The ICON Ion Velocity Meter (IVM) data product (L2.7) has been updated to version 8 revision 2 (v08r002) and is currently available for the full mission on the ICON FTP site and at NASA’s SPDF.   This is the final version of the IVM data product and should be used for all current and future analyses.   This product implements an updated algorithm to correct for offsets in ion drifts in the instrument frame and now includes estimated uncertainties for all derived geophysical quantities.
 
The electronic files (NetCDFs) can be found for the whole of the ICON mission at both the ICON FTP site and at the NASA SPDF.

ICON Level 3.2 O+ Ionosphere Is Now Available

Colin Triplett 0 363

The first of the ICON Level 3 products are now available: Level 3.2 O+ Ionosphere.  Each file contains 24 hours of ionospheric data merged from the EUV and FUV Level 2 (L2.5 and L2.6) data products.  All data are interpolated onto a common altitude grid. The FUV data use a weighted mean of values only within the central four stripes to match the EUV 12-degree horizontal field of view.  All data flagged as bad have been removed.  Files contain HmF2, NmF2, and O+ profiles for a 24-hour period.
 
These files can be found for the whole of the ICON mission at both the ICON FTP site and SPDF.

The MIGHTI temperature product (L2.3) has been updated to version 6 (v06) and is currently available for the full mission on the ICON FTP site and at SPDF. 

With this version update, the MIGHTI-A and MIGHTI-B temperature data are both more rigorously tested to ensure continuity across the solar terminator. Also, the top of the daytime MIGHTI-A temperature profiles is now 135 km, up from 127 km in previous versions. Links to the data products are provided here:
