Clear sky study

• flight track
• Averged HIS spectrum, all bands: rad | T_B
• Averaged HIS spectrum and uncertainty: band 1: rad | T_B; band 2: rad | T_B; band 3: rad | T_B
• SHEBA 980521 00129 UTC GLAS processed Vaisala RS-80 sonde
• Observed and calculated (CKDv2.1, HITRAN 96, gases 1-7, X-sections, SHEBA sonde + SAS profile) : all bands
  
  • band 1 :
    high altitude input temperature profile too cold
    730-740 cm^-1
    600-800 cm^-1
    791 cm^-1 Q-branch and water lines
    longwave window, ice emissivity
    ozone
    
  • band 2 :
    high J v2 band water lines
    methane
    v2 water band center
    strong water lines
    
  • band 3 :
    2080 Q-branch, water, etc.
    N₂O and CO
    high altitude input temperature profile too cold
    CO₂ v3 band band-head
