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.

ICON Temperatures Updated to Version 6, Now Available

Colin Triplett 0 56

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:

IVM Version 6 data now online

Version 6 of the IVM Level 2 data product is now available on the Public FTP site. It's a significant upgrade, and the release notes in the documentation describe the improvements to the product.

 

From that document. The V06 data product has been improved to handle large O+ fractions and to include cross-track ion drifts derived by neglecting inputs from the RPA.Data products has been corrected for long-term systematic offsets produced by uncertainties in the electrostatic environment of the spacecraft. The corrected variables are: ICON_L27_Ion_Velocity_X, ICON_L27_Ion_Velocity_Y, ICON_L27_Ion_Velocity_Z. They are used to compute the plasma drifts in magnetic coordinates. The uncorrected data may be accessed directly in the variables ICON_L27_Raw_Ion_Velocity_X, ICON_L27_Raw_Ion_Velocity_Y, ICON_L27_Raw_Ion_Velocity_Z Transverse ion drifts derived by neglecting RPA inputs may be accessed directly in the variables ICON_L27_Original_Velocity_Y, ICON_L27_Original_Velocity_Z. Short term variations with periods less than 10 days have not been removed but may be accurately assessed from examination of the zonal (daily) average of the meridional drift ICON_L27_Ion_Velocity_Meridional within 1 hour of 1800 MLT. Zonal averages in excess of 5 m/s over this local time range provide a reliable estimate of the short-term offset.
