TCCON: Atmospheric Greenhouse Gas Column Observations from Park Falls, USA

Ground-based Fourier Transform Spectrometer measurements from the Total Carbon Column Observing Network station in Park Falls, USA. The data provide column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO. This specific release (GGG2014.R0) is noted as obsolete by the author, P. O. Wennberg of the California Institute of Technology.

Use Cases

• Validate satellite-based greenhouse gas measurements based on the precise ground-truth data.
• Study long-term trends in atmospheric CO2 and CH4 concentrations based on the column-averaged abundances.
• Analyze correlations between different atmospheric trace gases like CO, H2O, and HDO based on the multi-species retrievals.
• Calibrate or evaluate atmospheric transport models based on the accurate column observations.

Strengths

• Data is from the established Total Carbon Column Observing Network (TCCON), a recognized source for validation.
• Provides column-averaged abundances for multiple key atmospheric constituents, including CO2, CH4, N2O, HF, CO, H2O, and HDO.
• Author and organization (P. O. Wennberg, California Institute of Technology) are specified, providing provenance.

Limitations

• The data is explicitly marked as obsolete and should be replaced by a newer version.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and temporal coverage are unknown, which may limit suitability assessment.
