Linelist Needs for the Atmospheric Chemistry Experiment

The Atmospheric Chemistry Experiment (ACE) is a satellite mission for remote sensing of the Earth's atmosphere, launched August 2003. The primary instrument on board is a high resolution (ñ25 cm maximum optical path di’erence) Fourier transform spectrometer operating in the infrared (750-4400 cm-1 ). Forward model calculations employ the HITRAN 2004 linelist. Observations from the mission will be used to illus- trate improvements relative to previous versions of the linelist. A wish list for future linelist development will be presented, including molecules that seem to require im- provements and molecules of atmospheric interest that we believe should be added to the linelist.
