The Montreal Protocol is working, but it will take several decades for ozone to return to 1980
levels. The atmospheric concentrations of ozone depleting substances are decreasing, and …

This article reviews our knowledge of long-term changes and trends in the upper
atmosphere and ionosphere. These changes are part of complex and comprehensive …

We report on updated trends using different merged zonal mean total ozone datasets from
satellite and ground-based observations for the period from 1979 to 2020. This work is an …

We report on updated trends using different merged datasets from satellite and ground-
based observations for the period from 1979 to 2016. Trends were determined by applying a …

The year was characterized by a transition from a waning La Niña to a strengthening El
Niño, which first developed in June. By December, SSTs were more than 2.0 C above …

Abstract The Solar Backscatter Ultraviolet (SBUV) Merged Ozone Data Set (MOD) provides
the longest available satellite‐based time series of profile and total ozone from a single …

Several large-scale climate patterns influenced climate conditions and weather patterns
across the globe during 2010. The transition from a warm El Niño phase at the beginning of …

The effect of the winter Brewer-Dobson circulation (BDC) on the seasonal and decadal
evolution of total ozone in both hemispheres is investigated using satellite total ozone data …

Abstract The Montreal Protocol has succeeded in limiting major ozone-depleting substance
emissions, and consequently stratospheric ozone concentrations are expected to recover …

The study presents a long-term statistical trend analysis of total ozone data sets obtained
from various satellites. A multi-variate linear regression was applied to annual mean zonal …
