ECMWF data are not available through plugings


  • Meteorologist

    @marekd @ivo @johnckealy

    It is very unfortunate that the ECMWF Organisation have prohibited the use of EC data for plugin development/use.

    I would like you to seriously consider the work done by John C. Kealy and his plugin (windy-plugin-skewt@0.2.6) and make this available as a feature within the Windy platform.

    I can vouch for this plugin from a professional Aviation Forecasting aspect and its usefulness and functionality within this role.

    Regards
    Craig

    @stitch Yes. Now we are quite occupied but soon I will make some proposal how to make all you guys "Windy developers" and your plugins Windy plugins.


  • Paraglider

    ECMWF was by far the most accurate and useful for my sounding plugin.

    I would be really interested in having access to ECMWF again.

    Thanks for your looking into this,
    Vic



  • @ivo
    Thanks. Very disappointing news. Was it any of our plugins that led to this decision by ecmwf?


  • Administrator

    @rittels No they just do not like the fact, that anyone else can use dataLoader a have access to ECMWF data. The argument that plugins just run on Windy.com did not helped a much.


  • Administrator

    @vicb Vince I have checked your plugin would you be willing to replace our official Sounding feature, with your plugin?

    I have no idea how to make it work in a way of source codes since our internal plugins are bundled with a client, but we can make it work.



  • @vicb
    Vince, thank you for providing this awesome plugin!
    Questions:
    1). Data from 250 hPa are included in your diagram?
    https://community.windy.com/topic/7963/upper-air-temperatures

    2). Is there a way to have hPa in the axis (instead of meters) and Knots for wind speed (instead of km/h) ?

    P.S. at https://github.com/vicb/windy-plugin-sounding
    you say: "The axis units match your windy settings."
    Although my settings are for hPa (pressure), ft (altitude) and kts (wind speed)
    the diagram shows m (altitude) and km/h (speed).


  • Paraglider

    @ivo I'm all for it if possible. As @Gkikas-LGPZ mentions the sounding is more adapted for paraglider pilots currently and I probably need to make some small changes:

    • The upper is currently set to 400hPa, changing it is only a setting,
    • The wind scale is non linear (0-30km/h on the left half, 30 to max on the right half),
    • I have done nothing to make it work on mobile screens.

    All of this should be easy enough and there could be a setting to have a generic version or a specialized version for paraglider (a checkbox).

    @Gkikas-LGPZ as mentioned above the current upper level is 400hPa but that's only a setting to change. I have just checked for the units. It seems like "ft" does not work ie altitude is always displayed in meters but "kt" works for me for the wind (You have to reload the page & plugin when you change the units). There is currently no way to have hPa on the y axis but that would be simple to implement.


  • Paraglider

    @Gkikas-LGPZ please check 0.8.2 that I have just published:

    • Changing the units in the preferences should now work for altitude,
    • There is a check box ("Zoom view") at the bottom to expand to graph up to 150hPa (zoomed view is up to 400hPa).

    You probably need to specify the name as sounding@0.8.2 when loading it for now.



  • @vicb
    Thank you very much!
    I want to mention that data for 250 hPa (34000 ft) are not included.
    Temp. @ d.p. line goes straight from 300 to 200 hPa (30 to 39 kft).



  • Hi all,

    I've just finished my placement at MetService New Zealand and I'm ready to get back to some plugin fun! It's a real shame about the ECMWF data loader, though knowing EC, I guess I can see their point of view.

    @vicb and I talked very briefly a few weeks back about collaborating. My suggestion would be this: how about if @vicb and I were to work on a new skewt/better sounding hybrid plugin? We could incorporate the best of both, have a nice zoom feature, a tick box for paraglider settings, cloud, options for wind arrows or barbs, mouseover data, mintra lines, customisable wind limits, etc.

    We could ask @ivo about the best way to write it so that it fits easily into the windy codes as a fully functional internal windy plugin, and not just an external one (are there really that many casual windy users who know about external plugins anyway?). Since @ivo is quite busy, now might be a good time to do it. And I'm sure @Gkikas-LGPZ and @rittels would be happy to help us test it properly.

    @vicb, if you prefer to keep better sounding and skewt separate, that's totally fine too. I'll start working on the new version of skewt if that's the case (I still haven't implemented the code suggestions you gave me ages ago, I plan to get into that stuff this week). But having one mega plugin that does it all and is fully available within the main windy site would be super cool, and I'd personally really get a kick out of seeing my work used like that.

    This is all a huge learning experience for me as an aspiring meteorological developer, and it's awesome for me to have the chance to contribute in these ways to my favourite weather site :)

    Thoughts?

    @vicb

    I've revisited your plug-in.

    Is it possible to include a numerical wind speed value next to the corresponding wind speed arrow column? The non-linear speed scale used in the vertical trace is difficult to use when determining the actual wind speed when the speed is very high through the vertical profile.

    Thanks
    Craig

    ECMWF status

    We will have a call with them tomorrow regarding licencing. We are unable to explain them, that plugins do no harm. We will let you know about result then


  • Paraglider

    Quick answers as I don't have much time right now
    @Gkikas-LGPZ There is no data at 250hPa for GFS
    @johnckealy It would be great if we can come with only one codebase and a few options. That would be less to maintain and more maintainers.
    @stitch I have a linear scale in unzoomed view ready. I only need to publish it, probably later today.
    @ivo great, thanks !



  • @ivo @vicb @johnckealy @okocedion @marekd @TomSlavkovsky

    They have to understand that it is not anybody who uses the dataLoader, really only a few of us. We can use gfs to experiment, and then apply for access to ecmwf, if the plugin qualifies. Obviously you will check that we do not post data elsewhere. Which we will definitely not do!!

    It would be great if the approved plugins are then more integrated in Windy.

    I really appreciate that you allow us to build plugins on windy. Great fun.




  • Paraglider

    What I meant is that 250hPa is NOT in the data loaded from the data loader - that is whatever is available to plugins for GFS.

    The windy UI might:

    • do an interpolation,
    • have more data available but I doubt as @ivo told me the opposite on an other thread.

    Did you check if that is not a simple interpolation ?



  • @vicb

    250 hPa data are not a simple interpolation.

    @vicb

    Your SkewT program is "hot topic" at the moment - credit where credit is due for your plugin.

    Could I throw another request at you? Are you able to make the parcel trace trajectory/potential cloud development feature available for all hours.
    Admittedly, in most cases the overnight period will have minimal surface parcel lift. However, I would like to see this option available for early morning and late afternoon (and even overnight) when certain convective situations could still provide surface parcel lift.

    Thanks again
    Craig



  • I noticed you had added a parcel trajectory too @vicb; I was wondering, how does it work? The parcel seems to have an origin temperature that is different from the surface temperature, so what is it based on?
