Description

We observed O I red (630 nm) and green (557.7 nm) nightglow using a spectrograph that observed 28 deg to 44 deg elevation in the sky in the north-east direction over a month around February 2022. We applied a 2-D extension to the Global Airglow (GLOW) model on the dataset. We show that neutral and electron densities input to the GLOW model require modifications to reproduce the observed intensities. The electron densities retrieved this way produce TEC that correlates with TEC values measured by the GNSS network, as well as a Digisonde stationed within 20 miles.
