EOF of Geopotential Height Diagnostic Module From NCAR¶

Current Developer: Dani Coleman (firstname.lastname@example.org), NCAR
Contributors: Dennis Shea, Andrew Gettleman, Jack Chen (NCAR)
This computes the climatological anomalies of 500 hPa geopotential height, then calculates the EOFs using NCL’s eofunc. The code is in NCL and requires model input:
monthly averaged surface pressure (ps),
monthly averaged geopotential height (zg).
Generates a netcdf file of climatological anomalies of 500 hPa geopotential height (compute_anomalies.ncl)
Calculates and plot EOFs of North Atlantic (eof_natlantic.ncl) and North Pacific regions using NCL function eofunc
Uses pre-made figures of eofs of NCEP observational data for comparison.
