Community Climate System Model Multi-Century Control Run Output

CCSM3.0 output data provides global climate simulations of Earth's past, present, and future states. The dataset includes multi-century control runs and scenario experiments like 1% increasing CO2 and 4 x CO2, with data from coupled atmosphere, sea ice, land, and ocean models. It is maintained by NCAR's Climate and Global Dynamics Division, with public data archived from runs conducted around 1990.

Use Cases

• Analyze monthly-mean time series of 2D atmospheric fields from CAM for long-term climate trend detection.
• Validate sea ice extent predictions using monthly-mean select fields from the CSIM component.
• Study ocean heat content changes with POP model's annual-mean 3D field time series.
• Compare land surface model outputs from 100-year CLM history files against observational datasets.
• Benchmark new model parameterizations against the 1870 control and 2 x CO2 scenario experiments.

Strengths

• Data originates from a fully-coupled, state-of-the-art global climate model (CCSM3.0).
• Includes multi-century control runs providing long-term baseline climate states.
• Covers multiple high-resolution scenarios (T85_gx1x3, T42_gx1x3, T31_gx3x5).
• A 2TB publicly available subset indicates substantial data volume.

Limitations

• Primary data source is archived from 1990, representing an older model version.
• Full original output requires an NCAR account for access, limiting availability.
• Specific row counts, column details, and sample data are not provided.
