ARPSIO

Format

This is for reading grid data in the ARPS grid format (it transparently supports both true ARPS ascii grids and grids modified by the ARPSGRID utility). DEM reading works well while reading meteo parameters might be a rough ride (since ARPS files do not always contain a consistent set of meteo fields).

It is possible to manually print the list of available variables as well as extract a whole section, for a given variable with the following one line scripts, in order to ease debugging:

awk '/^ [a-z]/{print $0}'  {arps_file}
awk '/^ [a-z]/{isVar=0} /^ radsw/{isVar=1;next} {if(isVar) print $0}' {arps_file}

Units

All units are assumed to be MKSA.
