Description
The Ozone Essential Climate Variable has been an essential part of ESA’s Climate Change Initiative (CCI, https://climate.esa.int/en/projects/ozone). This initiative strives to develop, mature, generate, and sustain harmonised, consistent, and validated multi-decadal satellite ozone time series specifically for climate monitoring, climate modelling, and climate research applications.
We summarise the Climate Data Records currently being developed by the CCI team and tailored to study processes and monitor the state of ozone across the troposphere. Different measurement techniques are employed which result in CDRs that encode different information about tropospheric ozone
- Convective cloud differential technique, applied to GOME-type sensors (1995-present, 20°S-20°N, 1 column between surface and 270 hPa).
- Limb-nadir matching technique, applied to the merged CCI total ozone and limb profile data sets (2004-present, global, 1 column between surface and thermal tropopause, or 3 km below).
- Profile retrieval technique, applied to nadir observations: 1995-present (GOME-type) or 2008-present (IASI), global, two columns in troposphere.
