The diagnostics package produces over 600 postscript plots and tables in a variety of formats from CESM (CCSM) monthly netcdf files. Climatological means for DJF, JJA, and ANN are used. The diagnostics package can be used to compare two model simulations or for comparing a model simulation to the observational and reanalysis data. Model output on gaussian or fixed grids can be used. The code has been tested on gaussian T31, T42, T85 and T170 grids and on fixed lat/lon grids. The diagnostics package is written completely in NCL (NCAR Command Language).

220.127.116.11 /home/comet/DIAGNOSTICS/ NCO: http://nco.sourceforge.net/ The netCDF Operators, or NCO, are a suite of programs known as operators. The operators facilitate manipulation and analysis of data stored in the self-describing netCDF format. Each NCO operator (e.g., ncks) takes netCDF input file(s), performs an operation (e.g., averaging, hyperslabbing, or renaming), and outputs a processed netCDF file.
NCL, a product of the Computational & Information Systems Laboratory at the National Center for Atmospheric Research (NCAR), is a free interpreted language designed specifically for scientific data processing and visualization. Numerous analysis functions are built-in NCL. NCL has robust file input and output. It can read and write netCDF-3, netCDF-4 classic, HDF4, binary, and ASCII data, and read HDF-EOS2,HDF- EOS5, GRIB1,GRIB2and OGR files (shapefile, MapInfo, GMT, TIGER).
