20010315: lots of missing data

Diana,
I probably need a clarification as to where "no stations
reporting at this time" is appearing. Is this in SNLIST?

If this is in SNLIST, then I'd need to see your input for
AREA and DATTIM, but let me start with the Denver example.

For Denver, the WMO id is 72469. So, if you give AREA=@72469,
then according to the etc/stat2000.txt file, you should start seeing
data about Oct 15, 1948. However, the station ID for this point is
LRY not DEN! So, if you gave AREA=@DEN, then you won't see any
upper air data until August 1956.

Also, the early sounding data is generally at 3Z and 15Z (instead of 0Z and 
12Z),
so you should be expecting that time difference as well. This is why I gave
the example that showed selecting all sounding times from the CD using
FSL's program (and not the option they provide of only 0Z and 12Z).

If you give DATTIM=list, you will see the available times in the file.
If you give DATTIM=ALL, AREA=@72469, then you will see the times that 
sounding data is available for Denver. If there are other times/stations
in the file, then there may be times where Denver doesn't exist.

So, using the example above, you you see any output for 72469 starting in 1948?
