Hourly CO2 and Meteorological Model Estimates for North America, 2010

North America is the geographic scope of this dataset containing estimated hourly atmospheric carbon dioxide mole fractions and meteorological observations for the year 2010. The data is generated at a 27 km horizontal grid resolution and a vertical range from the surface to 50 hPa using the Penn State WRF-Chem model. It is produced by the National Aeronautics and Space Administration, with model inputs from the CMS-Flux Inversion system.

Use Cases

• Validating regional carbon flux inversion models against high-resolution atmospheric CO2 simulations.
• Analyzing correlations between CO2 concentrations and meteorological variables like geopotential height, surface pressure, upper-air temperature, and upper-level winds.
• Studying the spatial and temporal distribution of atmospheric CO2 over North America at a sub-continental scale.

Strengths

• Provides a full year of continuous, hourly data for 2010, enabling detailed diurnal and seasonal analysis.
• Offers high spatial resolution (27 km grid) and vertical coverage from the surface to 50 hPa for North America.
• Data is generated by a recognized atmospheric model (Penn State WRF-Chem) constrained by a flux inversion system (CMS-Flux).

Limitations

• Sources conflict on the last updated date: one platform lists 2026-03 13, while another lists the end date of the data itself (2010-12-31).
• Specific column names and the total row count or dataset size are not provided by any source.
