This study analyzes tropospheric column ozone variability in the southern hemisphere as a function of ozone transport from the stratosphere to the troposphere and photochemical formation. Geographically, the study area was ...

Ozone concentration enhancement due to stratosphere-troposphere exchange was analyzed based on MOZAIC-IAGOS flights over Caracas, Venezuela, São Paulo and Rio de Janeiro, Brazil. The analyzed databases consisted on data ...

The knowledge of surface ozone mole fractions and their global distribution is of utmost importance due to the impact of ozone on human health and ecosystems and the central role of ozone in controlling the oxidation ...

Ozone (O-3) soundings have been performed on Easter Island or Rapa Nui (27 degrees S, 109 degrees W, 51 m a.s.l.) since 1994 as part of the Global Atmospheric Watch Programme of the World Meteorological Organization. In ...

In this Dissertation were identified events of influence of the Antarctic ozone hole over the South of Brazil that occurred in the period between 1979 and 2011. For this, we analyzed the daily average data of total ozone ...

The ozone mixing ratio spatiotemporal variability in the pristine South Pacific Ocean is studied, for the first time, using 21-year-long ozone (O-3) records from the entire southern tropical and subtropical Pacific between ...

This study discusses the influence of tropopause folding in ozone total column during the passage of frontal systems. This research aims to analyze, from the relations between the upper level jet and the ozone total ...

This work presents an analysis of a lowermost stratospheric air intrusion event over the coast of Brazil, which may have been responsible for a secondary surface cyclogenesis over the southwestern Atlantic Ocean. The surface ...

Given the importance of the ozone layer to life on the surface, an investigation on the dynamics of stratospheric ozone and its interaction with troposphere systems are conducted in this study. Being the focus of work ...
