The NCAR Command Language (NCL) is a programming language designed specifically for the access, analysis, and visualization of data. You can run NCL in interactive mode, where each line is interpreted as you enter it at your workstation, or in batch mode as an interpreter of complete scripts. The power and utility of NCL are evident in three areas: • File input and output. NCL reads in several data formats (netCDF, HDF, GRIB, CCM history tape, ASCII, and binary), and gives you immediate and easy access to the metadata in the file (where applicable). • Data processing. NCL contains over 300 built-in data processing functions, including specialized climate and model routines. You can also call Fortran or C subroutines from NCL scripts, making NCL infinitely configurable. • Graphical display. NCL generates publication-quality graphics on the fly using several specialized plotting scripts.
