A model, based on ozone-concentration tendency equation, is developed to study synoptic ozone-column variations. The application is referred to a middle-latitude site and to an atmospheric layer extending from the surface up to about 35-km altitude. Photochemical effects at the considered location for synoptic time scales are considered negligible. The data input consists of umkehr ozone profil...

The Madden–Julian Oscillation (MJO) is the dominant form of the atmospheric intra-seasonal oscillation, manifested by slow eastward movement (about 5 m s−1) of tropical deep convection. This study investigates the MJO’s impact on equatorial tropospheric ozone (10 N–10 S) in satellite observations and chemical transport model (CTM) simulations. For the satellite observations, we analyze the Trop...

The high resolution (5 cm-1) measurements of the outgoing infrared energy in the region of the 9. 6 ~ ozone band offer a means of determining the vertical distribution and total amount of ozone in the earth's atmosphere. With the application of radiative transfer theory and perturbation technique a method is developed t o deduce such information. The method hinges on a two-parametric representa...

In an open-top chamber study in east Texas, ozone-sensitive loblolly pine (Pinus taedu L.) seedlings were treated with either the antioxidant Ozoban (74.5% sodium erythorbate active ingredient (a.i.)) at 0, 1030, or 2060 mg liter-’ or ethylenediurea (EDU 50% a.i.) at 0, 150, or 300 ppm every 2 weeks while being subjected to a range of ozone exposures beginning in April 1994. The ozone exposures...

Abstract. We report on updated trends using different merged zonal mean total ozone datasets from satellite and ground-based observations for the period 1979 to 2020. This work is an update of reported in Weber et al. (2018) same up 2016. Merged used this study include NASA MOD v8.7 NOAA Cohesive Data (COH) v8.6, both based data series Solar Backscatter Ultraviolet (SBUV), SBUV-2, Ozone Mapping...

OBJECTIVE The associations between ozone concentrations measured outdoors and both morbidity and mortality may be partially due to indoor exposures to ozone and ozone-initiated oxidation products. In this article I examine the contributions of such indoor exposures to overall ozone-related health effects by extensive review of the literature as well as further analyses of published data. FIND...

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...

Early life is a dynamic period of growth for the lung and immune system. We hypothesized that ambient ozone exposure during postnatal development can affect the innate immune response to other environmental challenges in a persistent fashion. To test this hypothesis, we exposed infant rhesus macaque monkeys to a regimen of 11 ozone cycles between 30 days and 6 mo of age; each cycle consisted of...

[1] The Ozone Monitoring Instrument (OMI) project team uses two total ozone retrieval algorithms in order to maintain the long-term record established with Total Ozone Mapping Spectrometer (TOMS) data as well as to improve the ozone column estimate using the hyperspectral capability of OMI. The purpose of this study is to assess where the algorithms produce comparable results and where the diff...

Multiple-regression analyses have been performed on 32 years of total ozone column data that was spatially gridded with a 1× 1.5 resolution. The total ozone data consist of the MSR (Multi Sensor Reanalysis; 1979–2008) and 2 years of assimilated SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) ozone data (2009–2010). The two-dimensionality in this data set allows...
