The possibility that the stratospheric ozone layer could be depleted by half at certain
latitudes and seasons would have been deemed a preposterous and alarmist suggestion in …

Ozone plays a very important role in our atmosphere because it protects any living
organisms at the Earth's surface against the harmful solar UVB and UVC radiation. In the …

Atmospheric chemistry observations from space have been made for more than 30years.
They have been motivated by the concern about a number of environmental issues …

I present an analysis of ozonesonde data, synthesizing what is known about the distribution
of tropospheric ozone. Major features of the distribution are highlighted, and …

Recent findings, based on both ground-based and satellite measurements, have
established that there has been an apparent downward trend in the total column amount of …

Time series of stratospheric water vapor measurements by satellites and balloons show
persistent low values beginning in 2001. Temperature observations show that the tropical …

In this paper we discuss the methodology of taking broadband relative and absolute
measurements of ozone cross-sections including uncertainty budget, experimental set-ups …

An ozone climatology is presented, based entirely on ozone observations over the target
period 1980–1991. The climatology gives zonal mean ozone values, as well as the …

Analyses of a whole atmosphere chemistry‐climate model simulation forced by historical
sea‐surface temperature variations show that tropospheric El Nino–Southern Oscillation …

The experimental results, band structure calculations, and theoretical investigations carried
out within the framework of the many-electron models of half-metallic ferromagnets (HMFs) …
