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

Dr. Thomas Immel 0 15

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 #3

Winds and UV products all published

Dr. Thomas Immel 0 285

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.

First ICON Science Data Released to Public

Karin Hauck 0 683

[by Lina Tran on the NASA blog] On June 22, NASA’s ICON team released scientific data collected during the spacecraft’s first eight months in orbit to the public.

The data release features observations from ICON’s four instruments — MIGHTI, FUV, EUV, and IVM — which have been observing the ins and outs of the ionosphere, the sea of charged particles high in the upper atmosphere. Scientists have been busy parsing the wealth of observations collected by ICON in preparation for the mission’s first science results, which will be released later this year.

“ICON was designed, built, and launched to provide data we had never seen before, and it has not disappointed us in any regard,” said Thomas Immel, ICON principal investigator at University of California, Berkeley. Immel said he was pleased to share ICON’s first data with the world. “The sensitivity and precision of our observations, and the unique orbit and mission design, give us a new and advanced tool for unlocking all the puzzling questions we have had about the connection between Earth’s atmosphere and our space environment.”

The release coincides with the virtual summer meeting of CEDAR, the Coupling, Energetics, and Dynamics of Atmospheric Regions program. The newly released data spans measurements made since the mission’s launch on Oct. 10, 2019. Data can be accessed through University of California Berkeley’s Space Sciences Lab.

Newly-Launched ICON Observatory Sees the December 2019 Eclipse

What happens when airglow is temporarily “turned off”?

Karin Hauck 0 2772

Just over six weeks after launch and early calibrations, NASA’s Ionospheric Connection Explorer (ICON) mission was presented with a unique opportunity. ICON flew very close to the December 26 solar eclipse track that extended across Asia, and observed the major changes in upper atmospheric airglow that naturally occurred. ICON’s four instruments, primed to look at the ionosphere, the dynamic region where Earth meets space, were in position to observe the effects. What happens when airglow –the natural glow of Earth’s atmosphere caused by solar radiation – is temporarily “turned off” when the sun is blocked by the moon’s shadow for a few minutes? Preliminary data shows that all four instruments – MIGHTI, EUV, FUV and IVM – were able to see changes the eclipse wrought.
