Abstract
This dataset contains column-averaged dry-air mole fractions (mixing ratios) of carbon dioxide (XCO2). It has been produced using data acquired from the Thermal and Near Infrared Sensor for Carbon Observations - Fourier Transform Spectrometer-2 (TANSO-FTS-2) Near Infrared(NIR) and Shortwave Infrared (SWIR) spectra, onboard the Japanese Greenhouse gases Observing Satellite (GOSAT-2), using the RemoTeC SRFP Full Physics Retrieval algorithm. Results are provided for the individual GOSAT-2 spatial footprints.
These data have been produced as part of the European Space Agency (ESA)'s Climate Change Initiative (CCI) programme.

| Title | The SRFP (Remotec) Full Physics retrieval algorithm |
| Abstract | The RemoTeC retrieval algorithm has been jointly developed at SRON and KIT to retrieve column-averaged methane and carbon dioxide, using a 'Full Physics' retrieval technique. Details of the technical aspects of the retrievals can be found in the ATBD (see documentation links) |
