ncdf_read_2d() - generic reading routine

INTERFACE:

    subroutine ncdf_read_2d(ncid,varid,field,il,ih,jl,jh)

USES:

    IMPLICIT NONE

DESCRIPTION:

A two-dimensional netCDF variable with specified global range il < i < ih and jl < j < jh is read into field. It is checked if the sizes of the fields correspond exactly. When calling this funtions, remember that FORTRAN netCDF variables start with index 1. INPUT PARAMETERS:

    integer,          intent(in)        :: ncid
    integer,          intent(in)        :: varid
    integer,          intent(in)        :: il,ih,jl,jh

OUTPUT PARAMETERS:

    REALTYPE, intent(inout)             :: field(:,:)
