Atmospheric CO2 retrieved from ground-based near IR solar spectra
[1] The column-averaged volume mixing ratio (VMR) of CO2 over Kitt Peak, Arizona, has been retrieved from high-resolution solar absorption spectra obtained with the Fourier transform spectrometer on the McMath telescope. Simultaneous column measurements of CO2 at 6300 cm 1 and O2 at 7900 cm 1 were ratioed to minimize systematic errors. These column ratios were then scaled by the mean O2 VMR (0....
متن کاملTropospheric methane retrieved from ground-based near-IR solar absorption spectra
[1] High-resolution near-infrared solar absorption spectra recorded between 1977 and 1995 at the Kitt Peak National Solar Observatory are analyzed to retrieve column abundances of methane (CH4), hydrogen fluoride (HF), and oxygen (O2). Employing a stratospheric ‘‘slope equilibrium’’ relationship between CH4 and HF, the varying contribution of stratospheric CH4 to the total column is inferred. V...
متن کاملAtmospheric hydroxyl radical (OH) abundances from ground-based ultraviolet solar spectra: an improved retrieval method.
The Fourier Transform Ultraviolet Spectrometer (FTUVS) instrument has recorded a long-term data record of the atmospheric column abundance of the hydroxyl radical (OH) using the technique of high resolution solar absorption spectroscopy. We report new efforts in improving the precision of the OH measurements in order to better model the diurnal, seasonal, and interannual variability of odd hydr...
متن کاملAtmospheric carbonyl sulfide (OCS) variation from 1992-2004 by ground-based solar FTIR spectrometry
Analysis of ground-based high-resolution solar FTIR absorption spectra from four sites was performed to determine trends and variability in OCS columns over the period 1992–2004. The sites were Wollongong, Australia (34.45° S, 150.88° E), Lauder, New Zealand (45.0° S, 169.7° E), Arrival Heights, Antarctica (77.8° S, 166.6° E) and Mauna Loa, Hawaii (19.5° N, 155.6° W). Small but significant long...
