NCAR CESM Bias-Corrected Climate Model Output for WRF and MPAS

Global bias-corrected climate model output from NCAR's CESM1 model participating in CMIP5 for IPCC AR5. Data provides all variables needed for initial and boundary conditions in WRF or MPAS simulations, interpolated to 26 pressure levels at six-hour intervals. Files cover a 20th Century simulation (1951-2005) and three RCP future scenarios (2006-2100).

Use Cases

• Initializing WRF simulations using bias-corrected atmospheric variables at 26 pressure levels.
• Providing boundary conditions for MPAS model runs across future RCP4.5, RCP6.0, and RCP8.5 scenarios.
• Comparing bias-corrected model output against ERA-Interim reanalysis fields for the 1981-2005 period.
• Analyzing climate variable trends across the 1951-2100 time range provided in six-hourly files.
• Studying the impact of bias-correction methods on model performance for specific atmospheric features.

Strengths

• Data spans a 155-year period from 1951 to 2100.
• Variables are provided at six-hour intervals and interpolated to 26 pressure levels.
• Includes three distinct future climate scenarios (RCP4.5, RCP6.0, RCP8.5).
• Bias-correction applied using ERA-Interim reanalysis for a 25-year baseline (1981-2005).

Limitations

• Specific variable names, row counts, and file sizes are unknown.
• Data format is specialized for WRF/MPAS (Intermediate File Format), limiting direct use in other models.
• Future scenario projections rely on model assumptions inherent to the CMIP5 framework.
