I used gribtocdl and gribtonc to convert NCEP reanalysis2 GRIB data to
netCDF. The resulting netCDF file contains the correct time levels (124)
represented as RECORD dimension and all the variables are a function
of this dimension. However, there is no data for RECORD in the data
section. The data section contains values for reftime, valtime,
datetime, valtime_offset and forecasttime. As a result, plots of the
data show it as a function of 124 records, instead of the correct values
as a representation of "hours since 1992-01-01..." The correct values
are represented in the data section under reftime and valtime and the
strings are correct for datetime and forecasttime. Is the correct
solution to manipulate the CDL file and make the variables a funtion of
valtime instead of record?

Lori,

no quite sure i understand fully what you  are saying, but if valtime
works...     could you send me your cdl file and the resulting netcdf file
with the data section, actually you could just send a ascii representation
of the vars reftime, valtime, datetime, valtime_offset and forecasttime.
also do you have a sample grib file i can get?

robb..,

Thanks in advance,
Lori
