Mike,
It appears that you downloaded daily averages from CDC, instead of the 4x per
day files.
See: http://www.cdc.noaa.gov/cdc/data.ncep.reanalysis.html#surface
You will find on that page the sentances:
------------------------ snip ------------------------------
Availability and usage restrictions:
* By anonymous FTP:
o 4x daily data are available from ftp.cdc.noaa.gov in
/Datasets/ncep.reanalysis/pressure/.
o The 4x data files are quite large, so you may only be able to download
them if you have a fast network connection.
o Daily averages are available from ftp.cdc.noaa.gov in
/Datasets/ncep.reanalysis.dailyavgs/pressure/
------------------------ snip ------------------------------
The FTP link I used to download the shum data from CDC is:
ftp://ftp.cdc.noaa.gov/Datasets/ncep.reanalysis/pressure/
Also note, you have 12 months of data in your GEMPAK file. That would
eventually cause a
problem with the 1000 times allowed in the file when you have the 4x per day
data.
As I mentioned previously, you can use the YYYYMM template in the file name so
that the
decoder creates the appropriate monthly files:
*dcreanal shum.1978.nc YYYYMM_shum.gem
That will create output files 197801_shum.gem through 197812_shum.gem. Repeat
for all files to
decode.
