Erik,<br><br> I am not involved with the <a href="http://nomads.ncep.noaa.gov">nomads.ncep.noaa.gov</a> server except as a user. Clarissa said that people<br>who accessed GDS too frequently got an access denied. My guess is that IP addresses that accessed<br>
the GDS server too many times in one minute (my guess) were denied service for a short period time (5 minutes?).<br>Your NAM download script may be fine but GFS and RAP scripts are accessing the data too many times. My suggestions<br>
are to combine downloads and add some sleep commands into your script.<br><br>You might consider using grib-filter.<br><br>Wesley<br><br><br><br><br><br><br><br><div class="gmail_quote">On Mon, Aug 26, 2013 at 12:59 PM, Erik D.
