Summary Abstract: A microwave experiment was installed at Scott Base to measure microwave emission of atmospheric chlorine monoxide (ClO) near 1.1 mm wavelength by a heterodyne spectrometer. The heterodyne techniques allows very high spectral resolution revealing the details of the pressure-broadened line shape. Because the line is pressure broadened, its shape is sensitive to the vertical distribution of the ClO and that distrubtion can be retrieved with vertical resolution of about 10km. The data (raw = times and recorded microwave emission spectra, derived = column amounts and vertical profile information of chlorine monoxide (ClO)) are held at SUNY and in the NDACC database.
