Only one set of METARs in archived data?

[Guest steku]

I thought that in 6-hours archives you have all METARs (for example if METARs were ussued every hour I thought that in 6 hour set I will have all six metars for every hour). But this isn't true. Am I correct?Only the TAF processing can produce changing weather when you are in off-line mode? Is this true?

Hi,No, your will get 6 hours of METARs in an archived download, one for each hour.In Offline mode TAF processing is used when the TAF is more receint than the METAR. Both will produce changing weather.Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg

Hi,One snapshot is taken every 6 hours and archived. Each snapshot contains only one report for that valid time (00Z, 06Z, 12Z, 18Z).Yes, TAF processing must be on to get wx changes in off-line mode.Hope that helps!

DamianJim says that in an archive you get the weather for each hour - in other words six snapshots of weather in each archive - but you are saying that you only get one snapshot in each archive.Who is right? :-hmmm David

I would say Damian is right. Not that I don't trust Jim, on the contrary! But, this 4 times a day saving does explain why I sometimes get other archived weather than I would expect. I guess like in real life TAF weather can differ from the actual weather at a given time. I too thought 1 archive cycle would contain 6 hourly saved METARS per airport.Kind regards,Henk-Jan

Hi All,Just to let everyone know, Damian is correct. I had the misunderstanding and Damian sent me a p e-mail last night educating me a little bit more. We work back and forth like that, helping each other out when the need arises!However, in the future there are plans to have hourly data saved to the server. I don't know when and will not guess when!!Thanks All.Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg
