AWI-CM3: Historical and CO2 Scenario Climate Model Output

1850-2014 annual means from the AWI-CM3 version 3.0 model include near-surface temperature, precipitation, radiation, wind, and ocean variables. A 4xCO2 simulation covers 1850-1970, and a 1% per year CO2 increase simulation spans 1850-2010. The data was produced by Jan Streffing at the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.

Use Cases

• Analyze long-term climate trends based on annual means of near-surface temperature (T2M) and precipitation (PRECIP)
• Study cloud and radiation feedbacks based on total cloud cover (TCC) and surface/top radiation variables
• Evaluate ocean-ice interactions based on sea ice concentration (CI, a_ice) and mixed layer depth (MLD2)
• Compare model responses to different CO2 forcing scenarios based on the 4xCO2 and 1% per year increase experiments

Strengths

• Includes three distinct simulation experiments (historical, 4xCO2, 1% per year CO2) with defined time ranges
• Provides 20+ physical variables spanning atmosphere, ocean, and ice components
• Data originates from a recognized climate modeling institution (Alfred-Wegener-Institut)

Limitations

• Column-level documentation 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
