HAO Colloquium - Small-scale waves in the volume emission rate and wind products of the ICON/MIGHTI instrument

Speaker: Colin Triplett, University of California, Berkeley

NASA’s Ionospheric Connection Explorer (ICON) was launched in October of 2019.  Using a suite of instruments, ICON gives a unique view of the equatorial and mid-latitude neutral atmosphere and ionosphere.  The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) gives both neutral wind and temperature data through the use of different airglow layers. From the start of the mission, we have seen waves in the green line (557.7 nm) volume emission rate (VER) and wind measurements from the MIGHTI instrument.  These waves have wavelengths on the order of 1000 km throughout the daytime dataset.  In order to understand these waves we use a wavelet-based peak finding technique in the daytime VER and winds between 90 km and 160 km.
