Annual net flux estimates of carbon between land ecosystems and the atmosphere from 1850 to 1990. The data quantifies emissions resulting from deliberate land cover changes like forest clearing for agriculture. It is provided by the CEOS_EXTRA organization, with the latest data point from 1990.
Use Cases
- Model historical carbon budgets by analyzing the annual net flux time-series.
- Correlate periods of agricultural expansion with spikes in the annual carbon flux data.
- Validate Earth system models by comparing simulated land-use change emissions against this flux record.
- Assess the long-term climate impact of forest clearing using the 140-year flux timeline.
Strengths
- Provides a 141-year continuous annual time-series from 1850 to 1990.
- Focuses specifically on carbon flux from deliberate human land-use changes.
Limitations
- Data ends in 1990, lacking coverage for recent decades with accelerated land-use change.
- No column details are available to assess the granularity or supporting variables.
