Daily Modeled Carbon Exchange for AirMOSS Sites, 2012-2014

Seven sites across the United States are covered by this dataset, which provides Level 4 daily estimates of Net Ecosystem Exchange (NEE) of CO2 at a 1 km resolution. The data were produced by NASA's Ecosystem Demography Biosphere Model (ED2), augmented with AirMOSS-derived root zone soil moisture inputs. Daily estimates are generally available from October 2012 through October 2014, with time ranges varying by site.

Use Cases

• Modeling the sensitivity of carbon fluxes to soil moisture using the integrated ED2 model outputs.
• Validating and diagnosing predictions of Net Ecosystem Exchange (NEE) for specific biomes.
• Analyzing spatial patterns of carbon exchange at a 1 km resolution across seven distinct sites.
• Studying temporal trends in daily CO2 fluxes from 2012 to 2014 for specific AirMOSS flight regions.

Strengths

• Data integrates AirMOSS-derived root zone soil moisture to constrain and improve model estimates of carbon fluxes.
• Provides high spatial resolution (30 arc-seconds, ~1 km) daily estimates for seven distinct sites.
• Covers a multi-year time range, generally from October 2012 to October 2014.

Limitations

• Exact temporal coverage varies by site and is not uniformly specified across all records.
• Conflicting 'last updated' metadata exists between platforms (2014 vs. 2026), casting doubt on provenance clarity.
• Specific column names and row counts are not provided in any source description.
