OI λ8446 Archives

One-month snapshots of the 2-D distribution in terrestrial coordinate of the oxygen emission in (a) May and (b) December 2025. The measured emission is averaged over 31 days in latitude and longitude bins of 5-degree bin width. The corresponding absolute SZA is plotted in (c) and (d), with the color limit reversed to denote lighter color means closer pointing to the Sun. A movie showing the month-by-month evolution of the oxygen emission and solar zenith angle is available online. -- physics.ao-ph

Observations Of Atmospheric Helium And Oxygen With SPHEREx

by Keith CowingMay 6, 2026May 6, 2026

We present measurements of near-infrared (NIR) terrestrial airglow produced by helium and oxygen in the exosphere as observed by SPHEREx. Using eight months of survey data obtained from a 680 […]
