Rubén,Yes, each update should happen every 6 hours, but this is not exact, because the process of data dissemination depends of many factors. Some delays could happen.
As general rule, the data for 06UTC analysis is available 5-6 hours after. http://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.2016121506/ but another delay could happen to update the dataset on the thredds server. It may be someone else has the answer. Regards Antonio On 14/12/16 14:40, Rubén Vázquez wrote:
One last question Antonio. At what time UTC could call the xml for each update of the model. It's every 6 hours right? What I want is to save the xml data in each update to serve it on the map. At what time UTC do I have to program in CRON? Thank you very much.> El 13 de diciembre de 2016 a las 20:00 "Antonio S.
