High-altitude infrared remote sensing is a promising new method for measuring coronal plasma and magnetic fields. This talk presents recent results from Smithsonian’s Airborne Infrared Spectrometer (AIR-Spec) and outlines concepts for future airborne and balloon-based spectrometers and spectro-polarimeters.

AIR-Spec is an imaging spectrometer that measures light over a 0.4 degree field of view in three spectral passbands between 1.4 and 3 microns. The instrument was commissioned during the 2017 total solar eclipse, when it observed five coronal emission lines from the NCAR Gulfstream V research jet. During the 2019 eclipse, significant instrument improvements enabled high-precision measurements higher in the corona. A third flight is planned for December 2020, and a new balloon-based instrument is being designed based on the results of the aircraft missions.
