Problem to open netcdf files from NARR!

[Don Hooper]

Matias,

The sdfopen/xdfopen code can't handle this file, but the "dtype netcdf"
stuff for a DDF for use with the "open" command can in 1.9.  Here's a
sample DDF for that purpose:
DSET /path/to/apcp.mon.mean.nc
DTYPE netcdf
TITLE NARR 4D field lambert conformal projection
UNDEF -9999.0 missing_value
UNPACK scale_factor add_offset
PDEF 349 277 lcc 1 -145.5 1 1 50 50 -107 32463.41 32463.41
XDEF 205 linear 150 1
YDEF 85 linear 2 1
ZDEF 1 levels 0
tdef 312 linear 00z1jan1979 1mo
vars 3
apcp 29 t,y,x  Precip
lat=>glat 0 y,x Latitude
lon=>glon 0 y,x Longitude
endvars

Good luck,
-Hoop
