CCCMA's CGCM1 model produced daily and monthly climate parameter grids at T32 resolution. The dataset includes decadal and smoothed 30-year running means for parameters like temperature, precipitation, and winds. SCIOPS processed the model outputs.
Use Cases
- Analyze decadal trends in surface temperature and precipitation from smoothed mean grids.
- Compare geopotential height and wind patterns at 850mb and 500mb across different forcing scenarios.
- Validate modern climate models against CGCM1 outputs for parameters like sea-level pressure and humidity.
- Study the impact of CO2 and sulfate aerosol forcing scenarios on radiation flux outputs.
Strengths
- Model outputs include daily and monthly grids for multiple atmospheric levels.
- Data processed into decadal means and smoothed 30-year running means for trend analysis.
- Grid resolution is approximately 3.75 degrees on a 97 by 48 latitude/longitude grid.
Limitations
- Specific row count, file size, and exact temporal coverage are unknown.
- Data represents model simulations, not direct observational measurements.
- Recommendation to use smoothed means indicates raw decadal outputs have high variability.
