Abstract: The Sentinel-5 Precursor (S5P) mission with the TROPOspheric Monitoring Instrument (TROPOMI) onboard has been measuring solar radiation backscattered by the Earth's atmosphere and its surface since its launch on 13 October 2017. Methane (CH4) and carbon monoxide (CO) data with a spatial resolution (initially 7 x 7 km2, upgraded to 5.5 x 7 km2 on 6th of August 2019) have been retrieved from shortwave infrared (SWIR) and near-infrared (NIR) measurements since the end of November 2017 and made available to the experts for early validation and quality checks before the official product release. In this paper, we present for the first time the S5P CH4 and CO validation results (covering a period from November 2017 to September 2020) using global Total Carbon Column Observing Network (TCCON) and Infrared Working Group of the Network for the Detection of Atmospheric Composition Change (NDACC-IRWG) network data, accounting for a priori alignment and smoothing uncertainties in the validation, and testing the sensitivity of validation results towards the application of advanced co-location criteria.
Sponsorship : Part of this study has been carried out in the framework of the Copernicus Sentinel-5 Precursor Mission Performance Centre (S5P, MPC) contracted by the European Space Agency (ESA/ESRIN, Contract No. 4000117151/16/I-LG) and supported by the Belgian Federal Science Policy Office (BELSPO), the Royal Belgian Institute for Space Aeronomy (BIRA-IASB). Part of this study has also been supported by the S5P Validation Team (S5PVT) AO project TCCON4S5P (ID #28603, PI Mahesh Kumar Sha, BIRA-IASB) with national funding from the BELSPO through the ESA ProDEx projects TROVA and TROVA-E2 (PEA 4000116692). This work contains modified Copernicus Sentinel-5 Precursor satellite data (2018–2020) post-processed by BIRA–IASB.
