Printer-friendly versionSend to friend The Ozone_cci project is part of the ESA Programme on Global Monitoring of Essential Climate Variables (ECV), better known as the Climate Change Initiative (CCI), initiated in 2010.

The CCI Programme wants to contribute to the data bases collecting Essential Climate Variables (ECV) required by the United Nations Framework Convention of Climate Change (UNFCCC) and the International Panel on Climate Change. In particular, Ozone_cci will:

  • Analyze the needs of the climate research community in terms of Ozone data.
  • Adapt the Ozone satellite measurements for their use by the climate research community.
  • Use Ozone data available in the ESA Earth observation archive, as well as Ozone data from Third Party Missions (TPM). (TPM data come from instruments owned by other parties than ESA)

Three main product lines will be developed:

  • Total ozone from nadir UV backscatter sensors
  • Ozone profiles from nadir UV backscatter sensors
  • Ozone profiles from limb and occultation sensors

Ozone products and equivalent CMIP5/Obs4MIPs Parameters

The table below shows the Ozone outputs that have equivalent CMIP5 parameters and hence are suitable for submission to Obs4MIPs (Observations for Model Intercomparisons), an activity to make observational products more accessible for climate model intercomparisons.
