    • RE: Adding new ICON-D2 model

      @ivo if I may add a suggestion:

      The recent ICON/ICON-xx come in several distribution forms, two of which are:

      • standard pressure levels (1000hPa, 950/925 etc )
      • "half height levels" (= 65 layers which seem to be geodaetic heights, not pressure levels)

      for the vertically oriented (=aviation folk of various shapes and forms) the higher resolution would be useful - at least in the "VFR layers" (= below 5000m)

      it comes at a storage + processing cost though

      @korina It turns out Kachelmann is on the trail already:

    • RE: Adding new ICON-D2 model

      @justinlimbo seconded - it is the best short-term hires model around and I really recommend adopting it, it would be a major USP

      I've been using COSMO-D2 for ground condition forecasts before flights for years and it has been the most spot-on of the whole lot

      Unfortunately so far it's been available only via PC-met or the occasional off-beat weather website

      NB for aviation folk: the DWD models sport much higher vertical resolution internally (65 levels) than just the standard pressure levels

    • RE: station f076f530 - feeding or not?

      well it shows data again, so it seems to be released from lockdown ;)

    • station f076f530 - feeding or not?

      hi,

      I managed to bungle the feed from f076f530 on Friday 12-2 morrnings
      I have since restored the configuration, but do not see recent data in windy

      now I'd guess it makes sense to observe a new or reappeared station for a while before showing the data, but I'm unsure if my station actually feeds data

      how can I check the feed status on the windy side?

      best regards
      Michael

    • now that Melown is sold, what's up with 3D weather?

      Re: what about a 3D weather viewer?

      are you still going down this path @ivo?

      best regards

    • RE: Offline use of Windy

      @mhaberler Here's a proof of concept using the ICON-D2 short term weather model from DWD.de - grid 2km, about 35 elevation levels below 5000m - way beyond other models in horizontal and vertical resolution:

      it might not be that hard to integrate client-side reading of gribs for the determined

      I could read ICON-D2 wind u/v gribs just fine with this JS library: https://github.com/UdSAES/grib2-simple

    • RE: Offline use of Windy

      @curtis2010 I agree - reading grib files would be superb @ivo @rittels

      It would potentially fix a few issues with windy:

      • enable usage of models which are currently not supported in the stock windy models - for example the upcoming ICON-D2 (sequel to Cosmo-D2) which is very high resolution (2.2km, 27hrs in 3hr steps) and covers quite some Europe (page 12)
      • it could fix the 'no history in windy' issue - by viewing and downloading archived gribs
      • in the case of the trajectory plugin, it could improve both horizontal as well as vertical resolution substantially - for instance, ICON-D2 hast some 91 levels of which about 25 are in the 0-6000m regions which is relevant for me
      • enable viewing values which are not in the stock windy layers set. Example: the vertical wind component in ICON-D2.

      I concur that the 'market' of current grib reader apps is ready for some disruption...

      I'd not necessarily be asking the windy folks to "support that feature" by taking on the load of supporting an extra model or new layers. That is substantial effort.

      However, a blessed route to achieve this by say an API to introduce custom layers and data sources - maybe via a plugin and a local WMS server á la SkinnyWMS serving gribs would be great!

      Michael
