EOF of Geopotential Height Diagnostic Module From NCAR ====================================================== Last update: 03/11/2019 Contact info ------------ - Current Developer: Dani Coleman (​bundy@ucar.edu​), 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: 1. monthly averaged surface pressure (ps), 2. 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.

Functionality ------------- All scripts can be found at: ``mdtf/MDTF_$ver/var_code/EOF_500hPa`` 1. Make anomalies (compute_anomalies.ncl) 2. Calculated and plots EOFs in N. Atlantic (eof_natlantic.ncl) and N. Pacific (eof_npacific.ncl) Preprocessed observational data from NCEP as gif images are located in ``mdtf/``inputdata/obs_data/EOF_500hPa`` Place your input data at: ``inputdata/model/$model_name/day`` index.html can be found at: ``mdtf/MDTF_$ver/wkdir/MDTF_$model_name`` Required Programing Language and libraries ------------------------------------------ All these scripts required NCAR Command Language Version 6.3.0 or higher Required input data to the module: 1) Monthly averaged surface pressure (ps) 2) Monthly averaged geopotential height (zg)
