Chance,

If the program is not locating the data, be sure the
NEXRIII template in $GEMTBL/config/datatype.tbl
matches the file naming you are using at your site.

Then, verify that your data dirrectories are current
eg, look in $RAD/NIDS/AMA/N0R etc and make sure that the
file times are within the 30 minute RADDUR window,
or increate the window.

>>Chance,

>>It sounds like gdradr is either:
>>1) not finding current radars within the 30 minutes (RADDUR)
>>    previous to the RADTIM
>>or
>>2) Not finding your radar data.
>>
>>When gdradr runs, it will list out to the screen the
>>radars it is using, or if they are too old. I might
>>need you to send me that output from the program.
>>
>>Verify that your radar data is within 30 minutes of current, or set
>>RADTIM back to the time of your data.
