BlueFlux Daily CO2 and CH4 Wetland Flux Model for Southern Florida

BlueFlux provides gridded daily estimates of carbon dioxide and methane fluxes for Southern Florida wetlands from 2000 to 2024. NASA's Carbon Monitoring System project developed these 500-meter resolution prototype products using a bootstrap ensemble random forest model trained on airborne and tower eddy covariance measurements. The model integrates MODIS remote sensing data to upscale flux predictions across the region.

Use Cases

• Calibrating and validating regional-scale carbon flux models using daily, gridded CO2 and CH4 estimates.
• Analyzing long-term trends in wetland greenhouse gas emissions from 2000 to 2024.
• Studying the spatial heterogeneity of flux intensity and uncertainty at a 500-meter resolution.
• Integrating modeled flux data with remote sensing observations for ecosystem process studies.

Strengths

• Data combines multiscale measurements from five seasonal airborne campaigns and long-term tower networks since 2004.
• Provides daily flux estimates and uncertainty at a consistent 500-meter spatial grid.
• Covers a significant 24-year time series from February 2000 to August 2024.

Limitations

• Conflicting last updated dates exist between sources (2026-03-13 on Data.gov vs. 2024-08 31 on NASA Earthdata).
• Specific column names and the total row or file size are not provided in any source description.
• Data is labeled as a prototype product, indicating it is a developmental version.
