C3S: Obs4MIPs format GOME-type Total Ozone Essential Climate Variable (GTO-ECV), Version 9.0
Abstract
This dataset contains a time series of monthly averaged total ozone column data from nadir-viewing satellite sensors in Obs4MIPs format. It has been reformated from Version 9 of the GOME-type Total Ozone Essential Climate Variable (GTO-ECV) product, that has been generated as part of the European Union Copernicus Climate Change Service (C3S) ozone project.
GTO-ECV is generated by combining measurements from several nadir-viewing satellite sensors (GOME/ERS-2, SCIAMACHY/Envisat, OMI/Aura, GOME-2/MetOp-A, GOME-2/MetOp-B, TROPOMI/Sentinel-5P, and GOME-2/MetOp-C) into one single cohesive record. The merging approach was developed in the framework of the European Space Agency’s Climate Change Initiative (ESA-CCI) ozone project.

The original GTO Version 9 product was generated as part of the European Union Copernicus Climate Change Service (C3S) ozone project. The merging approach was developed in the framework of the European Space Agency's Climate Change Initiative (ESA-CCI) ozone project. Data were converted to Obs4MIPs format within the ESA CCI Climate Modellers User Group (CMUG) project. |

| Title | Computation for: C3S: Obs4MIPs format GOME-type Total Ozone Essential Climate Variable (GTO-ECV), Version 9.0 |
| Abstract | The C3S: Obs4MIPs format GOME-type Total Ozone Essential Climate Variable (GTO-ECV), Version 9.0 dataset was generated by combining measurements from several nadir-viewing satellite sensors (GOME/ERS-2, SCIAMACHY/Envisat, OMI/Aura, GOME-2/MetOp-A, GOME-2/MetOp-B, TROPOMI/Sentinel-5P, and GOME-2/MetOp-C) into one single cohesive record. This was done using a merging approach developed in the framework of the European Space Agency's (ESA's) Climate Change Initiative Ozone project. Firstly, the separate pixel-based level-2 observation - produced by the GOME-type Direct FITting v4 retrieval algorithm (GODFIT) are converted into level-3 products per sensor i.e. daily and monthly averages on a regular grid of 1x1 degree in latitude and longitude. Before the individual level-3 data records are finally merged into one single product, adjustments are applied in order to minimize possible inter-sensor biases and/or temporal drifts. Due to its notable long-term stability one sensor (OMI/Aura) was selected to serve as a reference for the other instruments, which are then adjusted in terms of a correction that depends on latitude and time. A detailed description of the merging approach, the generation, and the geophysical validation of GTO-ECV is provided in Coldewey-Egbers et al. (2015, 2022), Garane et al. (2018) and Lambert et al. (2022). |
