Abstract

This dataset contains column-average dry-air mole fractions of atmospheric carbon dioxide (CO2), derived from the TANSAT satellite, using the University of Leicester Full-Physics Retrieval Algorithm (UoL-FP, also known as OCFP). This dataset is also referred to as CO2_TAN_OCFP. This version of the dataset provides data globally over land. For further information on the dataset, please see the linked documentation.

Initially this dataset contains two months of data (June and August 2017), delivered as part of the GHG_cci Climate Research Data Package 6. Additional time periods will be added in the future.

This data has been produced as part of the European Space Agency (ESA)'s Climate Change Initiative (CCI) programme, with support from the UK's National Centre for Earth Observation (NCEO).

Title UoL_FP: University of Leicester Full-Physics retrieval algorithm for retrieval of CO2 from TANSAT data
Abstract The University of Leicester Full-Physics Retrieval Algorithm (UoL-FP) is an optical estimation retrieval algorithm for TanSat (and other satellites). It is also known as OCFP as it was initially developed to work for the OCO (Orbiting Carbon Observatory) satellite, but has been adapted for other instruments. For the CO2 Full Physics product, it utilises the O2-A absorption band along with the weak CO2 band located at 1.6 um respectively to retrieve XCO2 (the column-average dry-air mole fraction of atmospheric CO2). The explicit consideration of scattering by this approach reduces potential systematic biases due to clouds or aerosols.
