Greenhouse gas (GHG) concentrations and physio-chemical water properties are available for a two-year period (January 2020 - December 2021) across twenty-six locations in the River Clyde and its tributaries and two locations within the Clyde estuary to support understanding of the GHG sources and sinks and their associated mechanisms in the Clyde catchment. Full details about this dataset can be found at https://doi.org/10.5285/c3527258-c9ab-40d9-af0c-ddedabbd67a1
