This paper summarises the validation of GOME total ozone retrieved using the Weighting Function Differential Optical Absorption Spectroscopy (WFDOAS) algorithm Version 1.0. This algorithm has been described in detail in a companion paper by Coldewey-Egbers et al. (2005). Compared to the operational GDP (GOME Data Processor) V3, several improvements to the total ozone retrieval have been introdu...

The NOAA Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar is a differential absorption lidar (DIAL) for measuring ozone concentration and aerosol backscatter profiles that was originally designed for nadir-looking operation from an airborne platform. In order to expand the capabilities of this system, we have reconfigured the TOPAZ system for ground-based zenith-looking operation an...

A new approach for retrieving total ozone from ERS2-GOME spectral data has been developed, which relies on feed-forward neural networks to perform the data inversion. Using selected GOME wavelength regions, instrument and geolocation data as an input, networks have been trained to determine atmospheric ozone in a one-step procedure. In order to train a neural network, an extensive database of c...

Abstract. The total ozone data over Europe are available for only few ground-based stations in the pre-satellite era disallowing examination of the spatial trend variability over the whole continent. A need of having gridded ozone data for a trend analysis and input to radiative transfer models stimulated a reconstruction of the daily ozone values since January 1950. Description of the reconstr...

Due to larger multiple scattering effects in the troposphere compared to that in the stratosphere, the optical path of tropospheric ozone is markedly enhanced (as compared with that of stratospheric ozone) in the Huggins bands from 310 to 345 nm. Model study of the direct and diffuse solar fluxes on the ground shows differences between tropospheric and stratospheric ozone. The characteristic si...

ozone is an important chemical constituent of the atmosphere, and stratosphere it protects the earth surface from harmful uv radiations, such that it is known as “good ozone” while, in the lower troposphere it is a highly oxidizing pollutant and known as “bad ozone”. it is also a greenhoure gas that can affect the climate. hence, the study of spatial and temporal variations of ozone is importan...

Ozone and nitrogen oxides (NO x ) are air pollutants with known associations to adverse health effects on humans. Few studies have simultaneously measured ozone and nitrogen oxides with high spatial resolution. The main aim of this paper was to assess the levels and variation of ground-level ozone, NO2 and NO x in two Swedish cities. An additional aim was to describe the levels of these polluta...

Objectives were to assess and estimate an association between exposure to ground-level ozone and emergency department (ED) visits for cellulitis. All ED visits for cellulitis in Edmonton, Canada, in the period April 1992-March 2002 (N = 69,547) were examined. Case-crossover design was applied to estimate odds ratio (OR, and 95% confidence interval) per one interquartile range (IQR) increase in ...

BACKGROUND There is accumulating evidence from various countries, including the UK, that ground level ozone concentrations are associated with increased daily hospital admissions for respiratory diseases. This paper estimates the impact of ozone episodes on daily hospital admissions for respiratory disease in Great Britain by combining locally based exposure-response relationships with mapped e...
