SPHEREx Measurements of Helium and Oxygen airglow

This resource contains fitted airglow amplitudes for all band 1 and 2 SPHEREx exposures from April to December 2025 as described in the paper "Observations of Atmospheric Helium and Oxygen with SPHEREx" (submitted to JGR: Atmospheres; 2026) The column headers included in the file are listed in the table below: 1 OBSID The unique observation identifier. 2 week The week in which the observation was made (e.g. week 17 refers to a week in April). 3 year The year in which the observation was made. 4 DATE-OBS The date in which the observation was made specified in UTC YYYY-MM-DDThh:mm:ss. 5 MJD-OBS The modified Julian date for the observation. 6 SGT_LAT_MIDPT The ground-track latitude of the SPHEREx satellite. 7 SGT_LON_MIDPT The ground-track longitude of the SPHEREx satellite. 8 Band1_1083He The Band 1 helium template amplitude in MJy/sr. 9 Band1_1083HeSig The error on the Band 1 helium 1.0830$\mu$m template amplitude in MJy/sr. 10 Band1_0845OI The Band 1 oxygen 0.8446$\mu$m template amplitude in MJy/sr. 11 Band1_0845OISig The error on the Band 1 oxygen 0.8446$\mu$m template amplitude in MJy/sr. 12 Band1_1129OI The Band 1 oxygen 1.1287$\mu$m template amplitude in MJy/sr. ( not used in our analysis) 13 Band1_1129OISig The error on the Band 1 oxygen 1.1287$\mu$m template amplitude in MJy/sr. ( not used in our analysis) 14 Band2_1083He The Band 2 helium 1.0830$\mu$m template amplitude in MJy/sr. 15 Band2_1083HeSig The error on the Band 2 helium 1.0830$\mu$m template amplitude in MJy/sr. 16 Band2_1129OI The Band 2 oxygen 1.1287$\mu$m template amplitude in MJy/sr. 17 Band2_1129OISig The error on the Band 2 oxygen 1.1287$\mu$m template amplitude in MJy/sr.
