WebKey words: Ozone, Huggins and Hartley bands, absorption cross-sections, concentration measure- ments. 1. Introduction Ozone is indisputably a minor atmospheric constituent which plays a major role in the physico-chemistry of the atmosphere. It is involved in the direct attenuation of solar irradiance, especially in the UV ...

WebJan 5, 1996 · Experimental data Absorption spectra of ozone in the 195-350 nm range corresponding to the Hartley and Huggins systems were recorded by steps of 0.01 nm, at five temperatures (218, 228, 243, 273, 295 K) for 1603 and at ambient temperature for 1803. The accuracy was estimated to be 1-3%. WebThis paper describes and assesses the performance of the RAL (Rutherford Appleton Laboratory) ozone profile retrieval scheme for the Global Ozone Monitoring Experiment 2 (GOME-2) with a focus on tropospheric ozone. Developments to the scheme since its application to GOME-1 measurements are outlined. ibuypower video card update

WebOzone was measured with an absorption photometer (Model 202 Ozone Monitor, 2B Technologies, Boulder, Colorado) based on the well-established absorption of the mercury line in the Hartley... WebFormed by combination of atomic and molecular oxygen, ozone is in turn photodissociated, mainly by solar UV radiation at wavelengths between 240 and 300 nm (in the strong O 3 Hartley bands and continuum), but also by longer wavelength visible solar radiation. WebOct 25, 2002 · [1] Ozone molecules are photolyzed in the strong photoabsorption band of the Hartley band at 230–308 nm, and the O(3 P j) photofragments produced by the photolysis are detected directly by a technique of laser-induced fluorescence around 130 nm.The quantum yield values for O(1 D) formation in the photolysis of ozone at 297 ± 2 … ibuypower user manual
