Near-simultaneous, 0.0035 or 0.007 cm−1 resolution infrared solar absorption spectra of tropospheric HCN, C2H2, CO, and C2H6 have been recorded from the Network for the Detection of Stratospheric Change station in Lauder, New Zealand (45.04°S, 169.68°E, 0.37 km altitude). All four molecules were measured on over 350 days with HCN and C2H2 reported for the first time based on a new analysis procedure that significantly increases the effective signal-to-noise of weak tropospheric absorption features in the measured spectra. The CO measurements extend by 2.5 years a database of measurements …
Ground-Based Infrared Spectroscopic Measurements Of Carbonyl Sulfide: Free Tropospheric Trends From A 24-Year Time Series Of Solar Absorption Measurements, C P. Rinsland, A Goldman, E Mahieu, R Zander, J Notholt, Nicholas Jones, D W. T Griffith, T M. Stephen, L S. Chiou

Solar absorption spectra recorded over a 24-year time span have been analyzed to retrieve average free tropospheric mixing ratios of carbonyl sulfide (OCS). The measurements were recorded with the Fourier transform spectrometer located in the U.S. National Solar Observatory McMath solar telescope facility on Kitt Peak (altitude 2.09 km, lat. 31.9°N, long. 111.6°W), southwest of Tucson, Arizona, and were obtained on 167 days between May 1978 and February 2002, typically at 0.01-cm−1 spectral resolution. A best fit to the time series shows an average mixing ratio of 566 pptv (1 pptv = 10−12 per unit volume) between 2.09 …
Validation Of Version 5.20 Ilas Hno3, Ch4, N2o, O3, And No2 Using Ground-Based Measurements At Arrival Heights And Kiruna, S W. Wood, G E. Bodeker, I S. Boyd, Nicholas Jones, B J. Connor, P V. Johnston, W A. Matthews, S E. Nichol, F J. Murcray, H Nakajima, Y Sasano

Ground-based measurements of O3 and NO2 columns at Kiruna (68°N) and Arrival Heights (78°S) were used to validate stratospheric profile measurements of the same species by the satellite-based Improved Limb Atmospheric Spectrometer (ILAS) flown between November 1996 and June 1997. In addition, measurements of HNO3, CH4, and N2O made at Arrival Heights are compared with measurements of these species by ILAS. Even though there were no temporal coincidences in the latter comparison, the ground-based data provide a climatological context for the ILAS measurements. ILAS profiles measured within 10° of longitude and 2° …
