High-resolution solar observations covering the 8 to 13 &mgr;m atmospheric window are now being carried out routinely at the Kitt Peak National Observatory (KPNO), Tucson, Arizona, using a 1 meter-path difference Fourier transform spectrometer. Such observations allow the simultaneous measurement of a large number of trace gases. Preliminary results for the three most important fluorocarbons, FC-11, FC-12 and FC-22 are reported here. These results, in the form of average mixing ratios, show the potential and illustrate the performance of the Kitt Peak interferometer for this application.
