Exploring Where Earth's Weather Meets Space Weather

The Ionospheric Connection Explorer (ICON), the newest addition to NASA’s fleet of Heliophysics satellites, launched on October 10, 2019 at 9:59 p.m. EDT. Led by UC Berkeley, scientists and engineers around the world came together to make ICON a reality.

The goal of the ICON mission is to understand the tug-of-war between Earth’s atmosphere and the space environment. In the "no mans land" of the ionosphere, a continuous struggle between solar forcing and Earth’s weather systems drive extreme and unpredicted variability. ICON will investigate the forces at play in the near-space environment, leading the way in understanding disturbances that can lead to severe interference with communications and GPS signals.

Tonga Volcanic Effects Data Online

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

Dr. Thomas Immel 0 247

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.

MIGHTI v5 wind product now processing

It's a very exciting update!

Dr. Thomas Immel 0 197

Version 5 of the MIGHTI thermospheric winds is on its way. We are currently processing all the line of sight winds and once these are approved, will be promoted to the public FTP site and then the NASA archive. This wind product fills some long data gaps bad due to solar contamination. In version 5 the effects of this contamination has been mitigated and most of the data has been recovered. It also un-tethers the zero wind from HWM, using the on-orbit calibration processes to determine zero.
