Ozone

The Ozone project focuses on the generation of multi-decadal time series of harmonised and consistent ozone data suitable to assess long-term changes in total ozone, as well as its vertical distribution.

About

Ozone is strongly linked to climate due to its influence on Earth’s radiative budget, absorbing solar UV radiation in the stratosphere and terrestrial infrared radiation in the troposphere. Due to these dual processes, the climate impact of changes in ozone concentrations varies with the altitude.

Human-produced chlorine and bromine-containing gases are responsible for major ozone losses in the lower atmosphere resulting in a cooling effect on the Earth's surface. In contrast, increases in tropospheric ozone, a result of air pollution, have a warming effect on the Earth's surface, thereby contributing to the greenhouse effect.

The Ozone project has been part of the ESA Climate Change Initiative (CCI) programme since it was initiated in early 2010. This project focuses on the generation of multi-decadal time series of harmonised and consistent ozone data suitable to assess long-term changes in the total ozone column, the tropospheric ozone column as well as its vertical distribution across the UT/LS and stratosphere.

Ozone_CCI climate data records are based on satellite nadir sensors such as GOME, SCIAMACHY, GOME-2, IASI, OMI and TROPOMI complemented by a series of limb-viewing instruments allowing for a comprehensive characterization of the ozone columns and vertical profiles at various horizontal scales. These data products are freely distributed to the international user community and several of these feed the Copernicus Climate Change Service (C3S).

Main activities include

Development of state-of-the-art level-2 and level-3 ozone retrieval algorithms
Long-term data record generation and reprocessing of historical data sets
Data characterisation and uncertainty analysis including geophysical validation
Fully traceable documentation on all steps of the data generation
User assessment by the project Climate Research Group (CRG) and the Climate Modelling User Group (CMUG)

Objective

The Ozone CCI project’s objectives are:

Develop advanced level-2 and level-3 retrieval algorithms applicable to nadir and limb sensor types, and apply them to long times-series of measurements with the aim to realize the full potential of existing and historical sensors
Improve the information content of ozone measurements in critical altitude regions (troposphere and UTLS) using the synergy between nadir and limb-type sensors
Link European data records to historical non-European data series to create consistent long-series of observations covering several decades, as required for climate change-related studies
Bring a significant impact on ozone related research at the international level, through active involvement in the WMO/GAW Scientific Assessments of Ozone Depletion, that are compiled every four years

Data

The latest global products are distributed on the Ozone_cci ftp site at the following address: ftp://cci_web@ftp-ae.oma.be/esacci

Note: to access the ozone data, preferably use an ftp client application (such as FileZilla or equivalent). The ftp site is also directly accessible via browser. In this case, a dialogue window will pop up to request a password. To proceed to the site, just click 'Enter' with a blank password.

A list of the currently available ozone data products is available here.

Warning: the ozone data products currently distributed through the ESA CCI Open Data Portal are outdated and superseded by data sets available from the project ftp site (level-2 products) or from the C3S Data Store (level-3 products). We are working on a revision of the Open Data Portal data base, which will be announced on this page as soon as it is ready.

Second Ozone_cci User Workshop

28-29 May | Online | Workshop on the ozone climate data records developed by the ESA CCI

Background
The European Space Agency’s Climate Change Initiative (CCI) aims to realise the full potential of the long-term Earth Observation archives collected by ESA and Third Party satellite missions.

Since 2010, the Ozone CCI team has been developing, maturing, generating and sustaining multiple complementary multi-decadal satellite ozone Climate Data Records (CDRs) tailored for climate monitoring, climate research and climate modelling applications.

The CCI ozone product portfolio consists of total and tropospheric ozone column data products as well as vertically resolved ozone products by nadir and limb-viewing sensors.

Interactive: ESA_cci Mean Total Ozone Column in Dobson Units (v1)

Workshop objectives

This second user workshop will be an online event (28-29 May 2024) is aimed at bringing together scientists involved in the generation of ozone Climate Data Records, as well as (potential) users of such multi-decadal ozone time series, and the broader ozone and climate communities:

presenting the state of the art in ozone Climate Data Record production;
discussing results from major Climate Data Record users, e.g., stratospheric ozone assessments for WMO/UNEP, tropospheric ozone assessments for TOAR II, studies focusing on UT/LS, evaluation of climate modelling, data assimilation and reanalysis;
collecting and updating user requirements for ozone Climate Data Records;
discussing remaining challenges for the generation of ozone Climate Data Records.

Call for abstracts

We welcome contributions from the Earth Observation, climate monitoring and climate modelling communities, specifically related to

recent developments and emerging challenges in the generation of long-term ozone Climate Data Records from satellite or ground-based sensors;
assessments of long-term ozone changes and variability in troposphere, stratosphere and UT/LS;
the evaluation of climate models, data assimilation and reanalyses using satellite Climate Data Records;
the combined use of ozone and other Essential Climate Variables (atmosphere, oceans, biosphere, cryosphere) to improve our understanding of the Earth system.

You are required to register to the workshop in order to submit an abstract. After submission you can modify/withdraw your abstract until the deadline.

More information (preliminary programme (UTC), registration, abstract submission) can be found at https://events.spacepole.be/event/185
