Environment Variables

RIP_ROOT

An important environment variable for the RIP system is RIP_ROOT.
RIP_ROOT should be assigned the path name of the directory where all your RIP program and utility files (color.tbl, stationlist, lookup tables, etc.) reside.
Typically (for cshrc shell):

setenv RIP_ROOT /my-path/RIP4

The RIP_ROOT environment variable can also be overwritten with the variable rip_root in the RIP user input file (UIF).

NCARG_ROOT

A second environment variable you need to set is NCARG_ROOT.
Typically (for cshrc shell):

setenv NCARG_ROOT /usr/local/ncarg   ! for NCARG V4
setenv NCARG_ROOT /usr/local/ncl     ! for NCL V5

NETCDF

Make sure to set the NETCDF environment variable before attempting to configure or compile RIP4.
Typically (for cshrc shell):

setenv NETCDF /usr/local/netcdf
