Thirty ensemble simulations model the impact of weak random forcing on North American and Eurasian ice sheets. The data presents anomalous freshwater flux to the oceans, calculated as the difference from an unperturbed model run. The model is based on the work of Tarasov and Peltier (1997), with parameters unchanged except for the applied forcing.
Use Cases
- Analyze ice sheet volume changes based on anomalous freshwater flux data.
- Study the impact of stochastic insolation forcing on modeled Pleistocene climate.
- Validate or compare climate model ensembles based on the thirty simulations.
- Investigate freshwater input to oceans from ice sheets over the last 122,000 years.
Strengths
- Data is derived from thirty ensemble simulations, providing a range of model outcomes.
- The temporal coverage spans 122,000 years before present to the present day.
- The model and its parameters are explicitly referenced to a published scientific study.
Limitations
- Column-level documentation beyond the two described columns is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
