ACE infrared spectral atlases of the Earth׳s atmosphere

•Atmospheric transmission spectra.•Average solar occultation spectra recorded from orbit by ACE Fourier transform spectrometer.•Spectra for Arctic summer, Arctic winter, mid-latitude summer, mid-latitude winter and tropics.

Five infrared atmospheric atlases are presented using solar occultation spectra from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) in low earth orbit. The spectral atlases were created for Arctic summer, Arctic winter, mid-latitude summer, mid-latitude winter and the tropics. Each covers the spectral range from 700 to 4400 cm−1 and consists of 31 spectra that span an altitude range of 6-126 km in 4-km altitude intervals. To improve the signal-to-noise ratio, each spectrum in the atlas is an average of at least several hundred individual ACE-FTS limb transmission spectra. Representative plots in pdf format at 10 km (troposphere), 30 km (stratosphere), 70 km (mesosphere), and 110 km (lower thermosphere) are also available.
