Ocean pCO2 and CO2 Flux Gridded Estimates for Northern Gulf of America

Gridded monthly estimates of surface ocean partial pressure of CO2 and air-sea CO2 flux for the northern Gulf of America from 2006 through 2010. The dataset was produced by NASA using MODIS/Aqua satellite imagery combined with ship-based observations and wind field data. It provides 1 km resolution maps for analyzing carbon dynamics in this coastal region.

Use Cases

• Analyzing spatial and temporal variability of ocean pCO2 using the 1 km gridded monthly estimates.
• Quantifying air-sea CO2 flux to assess the region's role as a carbon source or sink.
• Validating ocean carbon cycle models with satellite-derived pCO2 and flux data.
• Studying the influence of wind fields on CO2 exchange rates using the flux derivation method.

Strengths

• Provides high-resolution (1 km) gridded data for detailed spatial analysis.
• Integrates multiple data sources: MODIS/Aqua satellite imagery and in-situ ship observations.
• Covers a multi-year time series from 2006 to 2010 for temporal trend analysis.

Limitations

• Conflicting metadata: last update dates differ significantly between platforms (2011 vs. 2026).
• Specific column names, row counts, and exact file sizes are not provided by any source.
• Spatial coverage is limited to the northern Gulf of America.
