Spectroscope absorption measurements of the stratospheric trace gases hydrogen chloride (HCl) and nitric (HNO3) using a Fourier transform infrared spectrometer with the full moon as a light source at Arrival Heights
Spectroscope absorption measurements of the stratospheric trace gas hydrogen chloride (HCl) was measured using a Fourier transform infrared spectrometer with the full moon as a light source (sunlight reflected from the moons surface). Hydrogen chloride is extremely important as it is the principal reservoir species for stratospheric chlorine. The aim of this study was to better understand the annual cycle of chlorine and the winter processes leading to ozone depletion in the spring. Measurements are possible for around 5 days on either side of the moon, providing the sky is clear of cloud and the wind is not too strong.
This study was for a PhD thesis. The spectroscope absorption measurements should be contained in the manuscript or contact Stephen Wood firstname.lastname@example.org. Several other forms of data were used in this study obtained from long term data sets including:
OClO and NO2 data from diode array spectrometer. Please contact Karin Kreher email@example.com or Paul Johnston ... firstname.lastname@example.org
Total column ozone from Dobson spectrometer Please contact Sylvia Nichol email@example.com
Microwave emissions of ClO Microwave spectrometer data (ClO) held at SUNY and in the NDACC database. Please contact Stephen Wood firstname.lastname@example.org
