A data browser developed by Dr. Yen-Jung Wu here at SSL allows you to make plots of ICON data very quickly, and once the data are plotted provides a quick link to the file at the NASA repository. 

 

Tonga Volcanic Effects Data Online

Neutral winds and plasma velocities online, FUV ion density profiles now processing.

Dr. Thomas Immel 0 789

The January 2022 Tonga volcanic eruption produced some clear and remarkable effects in space that ICON saw directly. The new plasma drift data (Level 2.7 IVM v6)  and thermospheric wind and temperature data (Level 2.2, 2.3 MIGHTI v5) are on the ICON public FTP site for this event. The EUV instrument was not on, but FUV was, and we are currently completing the processing of FUV L1 data (which will be at v05 when they are published) to use in retrieval of both thermospheric composition and nighttime plasma density profiles for this event.

ICON Mission Operations Update #8 - New EUV Level 1 products and revised Level 2 retrievals

Level 2 version unchanged for now

Dr. Thomas Immel 0 790

The EUV Level 1 (L1) product containing EUV limb radiances has been updated to V3. This resolves primarily remaining issues with flatfielding. The Level 2 (L2) products are now re-run using these L1 inputs. The retrieval algorithm hasn't changed but the revision number has been indexed on the L2 products. This now extends the L2 products into 2021.

Mission Operations Update #6 - New Temperature Retrievals

MIGHTI 2.3 product up to Version 5

Dr. Thomas Immel 0 745

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.

ICON had a better year than most of us

Karin Hauck 0 971

Clearly the solution to the challenges of 2020 is to be in space, far above earthly problems. We’re celebrating one year since our launch on October 10, and – once past the electrical grid shutdowns that made launch challenging -- ICON has had a pretty rewarding year. Mission operations have gone smoothly, overcoming all challenges that have come up, and implementing a lot of calibration activities to enhance the science mission. Our instruments have gotten great data which are now available to the public. A number of ICON-related articles have gone to press or are heading there shortly, see our publications. We’re looking forward to Fall AGU to share our science results with a broad audience.
