    • RE: observation vs. forecast

      @idefix37
      Ok, I can see that could be useful in the case you describe.

      But if I want to know which model that on average most accurately forecasts 1, 2, or 3 etc days ahead, that display doesn't tell me that.

      Would be worth Windy writing an FAQ on this perhaps.

    • RE: Australian Digital Forecast Database ADFD as a model option?

      @Filip_K I think the ADFD doco was updated in 2023. There's now a single Australian national grid at ~5km resolution.

      Theoretically the ADFD should be better quality than raw model output.

      Reckon Windy should give it some thought!

    • RE: observation vs. forecast

      @idefix37 thanks for being patient with me.
      Am I right to say that the curves show the most recently available model run at the time of the observation?

      If that's the case then the curves show a comparison with the first several hours of the model runs only. :(

      @idefix37 thanks for the reply.
      Still struggling to understand this, but I think you are saying that the model forecasts plotted are ones that were initialised around a week ago (at the time the model plot curve starts).
      Correct?

    • Australian Digital Forecast Database ADFD as a model option?

      Just wondering if its possible for Windy to include the Australian Digital Forecast Database (ADFD) from BoM as a model display option? The ADFD is a gridded dataset based on multiple global and regional models but also edited by forecasters at BoM. Its similar to the US National Digital Forecast Database and some of the same tools (Graphical Forecast Editor) are used.

      You can access sample ADFD grids at ftp://ftp.bom.gov.au/anon/sample/catalogue/ADFD/
      Doco at http://www.bom.gov.au/catalogue/adfdUserGuide.pdf

      Why?

      I'd love to see the ADFD data in the the Windy "Compare forecasts" and "Observation v forecast" features!

      If you want to visualise the ADFD you can go to http://www.bom.gov.au/australia/meteye/
      (though its nowhere near as good as WIndy!!).

    • RE: observation vs. forecast

      @idefix37 are you saying that its a combination (median error?) of ALL forecast lead times for each model for the time in question?

    • RE: observation vs. forecast

      @Suty this doesn't answer the question asked. So I'll ask it differently. How are the forecast plot curves determined? A single forecast for a specific lead time? Or is a combination of forecasts over multiple lead times?
