DWD updates Icon EU and Icon D2 model every three hours. As far as I see, Windy only updates every six hours. Why doesn‘t Windy use these data to be more actual?

@mwicher Hi, thanks for letting us know. We will look at it.

@Korina
Thank you! You can see it at windguru.cz or Kachelmannwetter.de (meteologix.com). I would be happy if I could use these data in Windy as well as a premium user. Icon D2 is normally updated every three hours and ICON EU is sometimes called Icon EU flash, because they provide a shorter time window for the actualization between the six hours-window. It is a kind like ECMWF with the difference of eight runs a day (ICON) versus four runs (ECMWF). Best regards, Michael -

Sorry for replying to such an old article, but are these reference times? I ask this because my limited understanding is that, for example, the ECMWF model is updated using these reference times, but the actual time when the model update is publicly available for viewing within the Windy app is much later (by like 8 to 9 hours after the reference time according to a pinned FAQ article I read on here, but even that article was confusing since it states this and then give the example of 00:00 Z being the reference time for ECMWF and then gives 07:15 Z as the update time, which is less than the 8-9 hours stated in the article's previous paragraph).
To confuse matters further, the "update interval" listed on the app for the ECMWF model states "6-7 hours," which less than the update time given in the example given in the FAQ article. Also, the reference time currently listed at 2:18 PM EDT for the ECMWF model says 06:00:00Z (which is 2:00 AM EDT), but it says that it was last updated at around 10:44 AM EDT (14:44 Z) with the next update time at 3:44 PM EDT (19:44 Z). Why would it be showing a forecast with a 06:00:00Z reference time when it was last updated at 14:44 Z? I suppose that falls within the 8-9 hour update time range listed in the FAQ article though. If that's the case, then why is the next update time listed as being 7 hours and 44 minutes after the 12:00 Z reference time (which is when the next model update runs for ECMWF)? That falls neither within the 6-7 hour "update interval" listed on the app or within the 8-9 hour range listed on the FAQ article.
Additionally, the HRRR model is said to update hourly, but the updates seem to only occur every two hours at about about 33 minutes past the hour. The reference time currently listed for the HRRR model at 2:18 PM EDT is 16:00:00Z, which is 2:00 PM EDT. However, the app states that the last update occurred at 1:33 PM EDT with the next update occurring at 3:33 PM EDT. How can the reference time be later than the update time? I'm super confused by all of this.
I understand many different factors affect the processing and download times of each update, but is there an approximate average of how long it takes between the reference time and when the Windy app shows the latest update for each model? Can anyone help shed some light on this for me? Thanks!

Hello, I recommend checking this article which explains the difference between reference time and update time - https://community.windy.com/topic/11361/a-difference-between-reference-time-and-update-time
