Experiment Title

AMIP historic

Description

1. Experiment Configuration
   Conduct an atmosphere-only simulation similar to CMIP AMIP for the period 1980–2022 using high-resolution daily forcing

2. Model Settings
   Initial Conditions: Use ERA5 for atmosphere and land initial conditions on 1 January 1980.
   Spinup: Treat 1980–1981 as land surface spinup. Analyze 1982–2022.
   Forcing Interpolation: Interpolate daily mean fields (no diurnal cycle) to the model grid.

3. Forcing Data
   Use 0.05° ESA CCI SST v3.0 and OSI SAF sea ice concentration instead of the 1/4° HadISST.2.2.0 dataset.

4. Key Differences from CMIP6 HighResMIP
   SST Forcing: Upgraded to 0.05° ESA CCI SST.
   Land Spinup: 2 years recommended; alternative methods allowed if documented.
