The AER Line File Parameter Database contains AER and TES input spectoscopic line parameter databases built from HITRAN and from other community resources. Please see our reference and publications list for more details.

• Full Spectral Range: 0-25232 cm^-1; 44607-57028 cm^-1
• The current AER version is built from HITRAN2020 with notable exceptions for H₂O, CO₂, CH₄, O₂.
• The line files have been converted from HITRAN f160 to HITRAN f100 format.
• The line list covers the full HITRAN spectral region and is provided both as one total line list (line_file/*) and as separate individual line lists for each molecule (line_files_by_molecule/*)
• The line list does not include isotope 7 of O₂, and isotopes 10, 11, 12 of CO₂.
