Nitrogen Dioxide in the Stratosphere and Troposphere Measured by Ground-Based Absorption Spectroscopy

Abstract: The NO(2) abundance in the stratosphere has been determined from ground-based spectra of the rising and setting sun and moon and of the twilight sky near 4500 angstroms. The spectra were taken at the Fritz Peak Observatory, at an altitude of 3 kilometers in the Colorado mountains. Separation of the stratospheric contribution requires observations at a relatively unpolluted site; direct measurement of the tropospheric absorption in the Colorado mountains often yields an upper limit on the tropospheric mixing ra… Show more

“…By observing sunlight scattered from the zenith sky, they originally determined the total vertical amount of NO 2 , weighted to the stratospheric amount (Brewer et al, 1973;Noxon, 1975). The spectrum is analysed by least-squares fits of laboratory crosssections, after spectral filtering to eliminate slowly-varying spectral features -the so-called Differential Optical Absorption Spectroscopy (DOAS) method (Platt et al, 1979;Platt and Stutz, 2008).…”

“…Using its characteristic absorption bands in the UV and visible spectral range, NO 2 has been successfully measured for many years using the DOAS technique (Brewer, 1973;Noxon, 1975;Platt, 1994), both from the ground and from space (e.g. Richter et al, 2005;Beirle et al, 2011).…”

“…These two species occur both in stratosphere and troposphere [18,19,20,21] and, in particular, N 2 O is one of the main greenhouse gas and biomarker species, being released into the atmosphere mainly by biological sources [22 and references therein].…”
