Brewer spectrometer total ozone column measurements in Sodankylä [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2016
Brewer total ozone column measurements started in Sodankylä in May 1988, 9 months after the signing of The Montreal Protocol. The Brewer instrument has been well maintained and frequently calibrated since then to produce a high-quality ozone time series ...

OMI total column ozone: extending the long-term data record [PDF]

Atmospheric Measurement Techniques, 2015
The ozone data record from the Ozone Monitoring Instrument (OMI) onboard the NASA Earth Observing System (EOS) Aura satellite has proven to be very stable over the 10-plus years of operation.

The 1985 Southern Hemisphere mid-latitude total column ozone anomaly [PDF]

Atmospheric Chemistry and Physics, 2007
One of the most significant events in the evolution of the ozone layer over southern mid-latitudes since the late 1970s was the large decrease observed in 1985. This event remains unexplained and a detailed investigation of the mechanisms responsible for

Kelvin waves in total column ozone [PDF]

Geophysical Research Letters, 1994
Tropical Kelvin waves have been observed previously in ozone mixing ratio data from the SBUV (Solar Backscatter Ultraviolet) and LIMS (Limb Infrared Monitor of the Stratosphere) instruments on board the Nimbus‐7 satellite. The present study investigates Kelvin wave features in total column ozone, using version 6 data from the Total Ozone Mapping ...

Detecting the recovery of total column ozone [PDF]

Journal of Geophysical Research: Atmospheres, 2000
International agreements for the limitation of ozone‐depleting substances have already resulted in decreases in concentrations of some of these chemicals in the troposphere. Full compliance and understanding of all factors contributing to ozone depletion are still uncertain; however, reasonable expectations are for a gradual recovery of the ozone layer

Validation of the Aura Ozone Monitoring Instrument total column ozone product [PDF]

Journal of Geophysical Research: Atmospheres, 2008
This paper is an overview of the validation of the total column ozone data products from the Ozone Monitoring Instrument (OMI) on board the NASA EOS‐Aura satellite. OMI is an imaging UV/visible spectrometer that maps global ozone on a daily basis. There are two ozone products from OMI, one derived using the traditional TOMS retrieval algorithm and ...

Reconciliation of halogen-induced ozone loss with the total-column ozone record [PDF]

Nature Geoscience, 2014
The observed depletion of the ozone layer from the 1980s onwards is attributed to halogen source gases emitted by human activities. However, the precision of this attribution is complicated by year-to-year variations in meteorology, that is, dynamical variability, and by changes in tropospheric ozone concentrations.

A new ENSO index derived from satellite measurements of column ozone [PDF]

Atmospheric Chemistry and Physics, 2010
Column Ozone measured in tropical latitudes from Nimbus 7 total ozone mapping spectrometer (TOMS), Earth Probe TOMS, solar backscatter ultraviolet (SBUV), and Aura ozone monitoring instrument (OMI) are used to derive an El Nino-Southern Oscillation (ENSO)

A satellite‐derived ozone climatology for balloonsonde estimation of total column ozone [PDF]

Journal of Geophysical Research: Atmospheres, 1997
The standard technique for computing total column ozone from a balloonsonde measurement includes an extrapolation of the measured ozone profile to altitudes above the balloon burst altitude. This total column calculation can be improved by using a monthly average ozone climatology based on ozone profile measurements from the solar backscattered ...
