G. C. Toon (JPL) – Intermittent operation of a home-built interferometer (JPL MkIV with 0.006 cm 1 resolution) from August 1994 to July 2002. This instrument was also launched on a balloon periodically between October 1989 and 2014. A database of MkIV column abundances from twelve different sites covering 1985-2015 is in the archive. Sites include Mt. Barcroft, JPL (Pasadena, CA; 34.20˚N, 118.17˚W), Table Mountain Observatory, McMurdo Antarctica, and Ft. Sumner New Mexico.
