NASA Carbon Monitoring System data provides yearly average primary production and carbon fixation estimates for Lake Superior. The dataset is derived from MODIS satellite imagery combined with model data. GES DISC published this version, with a last recorded update in December 2013.
Use Cases
- Modeling yearly carbon fixation rates in Lake Superior using primary production estimates.
- Analyzing spatial patterns of aquatic productivity from the geospatial data layers.
- Correlating interannual variability in primary production with climate indices using the yearly time-series.
- Validating regional carbon cycle models with satellite-derived lake carbon data.
Strengths
- Data originates from NASA's Carbon Monitoring System, an authoritative source for carbon stocks and fluxes.
- Utilizes MODIS satellite imagery, a long-standing and calibrated sensor system.
Limitations
- Temporal coverage is unclear and the data has not been updated since 2013, indicating potential staleness.
- Specific spatial resolution, row count, and validation metrics are unknown.
Provenance
- Source

- Collection Method
- Derived from MODIS satellite imagery combined with model data.
- Time Range
- Yearly averages; specific years covered are unknown.
- Freshness
