[Rnomads-user] Import data

[Daniel Bowman]

Hello Carina,

To be honest, I have very little experience with grib1 files.  The
NOMADS system is entirely in grib2 format, with grib1 only appearing
in old archive data. I have provided very rudimentary grib1 reading
support, but I am not surprised if it is not working, particularly for
grib1 files not generated for NOMADS.

My recommendation is to use the following method to convert them to
grib2 format, then try reading them into rNOMADS:
http://www.cpc.ncep.noaa.gov/products/wesley/grb1to2.html

I will try it also and see if I can get it to work. It may be a few
days before I have a chance, however.

Best,

Danny
