Linelist of HD16O for study of atmosphere of terrestrial planets (Earth, Venus and Mars)

Studies of water vapor in the atmospheres of Venus, Mars and Earth by spectroscopic techniques are being made routinely with different instruments on board of interplanetary missions like Mars-Express, Venus-Express and many others as well as with a lot of spacecrafts on the Earth’ orbit. Accessibility of detailed spectroscopic information in a wide range is then of crucial importance to retrieve reliable results with these instruments. Unlike Earth, Mars and Venus have the CO2-rich planetary atmospheres that require line shape parameters for HDO–CO2 broadening. s paper a new linelist for HD16O is presented. This linelist covers the range of 0.00065–25,660 cm−1 and is significantly more complete than other databases presently available. All lines with intensities (for 100% abundance) greater than 10−30 cm/molecule at 296 K are included. Wavenumbers for 43% (about 300,000) of all lines were evaluated at a level of the best experimental accuracy. For each transition the line shape parameters such as halfwidth and temperature exponent are provided for the case of HDO–air, HDO–HDO, and HDO–CO2 broadening. The final linelist contains more than 700,000 HD16O lines and is presented in HITRAN-compatible format.
