I use u & v interpolations.
There is one gotcha when you do angle interpolation wrt to wrapping: avg(310, 50) is 0 not 360 / 2.
That's probably something we can try.
The thing is that different model report different things.
I think that EC has all of model elevation, actual elevation and sfc temp while GFS only has actual? elevation.
I have chosen to use the model elevation when available because what's below probably do not make a lot of sense ?
@stitch good catch. The line was still potted with the wrong scale in unzoomed mode. This should be fixed in 0.8.5. (You can specify the version when loading the plugin using the name
firstname.lastname@example.org before it becomes the default in a few hours).
With regards to the scale in zoomed mode:
The plugin is originally targeted to paraglider pilots.
That's why I do not display hPa but elevation on the y axis and stop at ~7000m.
Given that a paraglider fly at ~40km/h we are less interested in speed > 30km/h - we would start flying backward in gusts and also have turbulences.
That's why having more granularity in the 0-30k range is interesting - we are only remotely interested in >30.
It does not affect us that much: we wouldn't fly in that zone but knowing the max speed higher still could be interesting.
That being said I'm open to extending the plugin for more use cases - we started discussing that with @johnckealy.
What I do not want is to have to configure 20 different options to use the plugin but what I could imagine is to have a handful of different "profiles" (paragliding, meteo, ...) each having a sensible configuration.
Having a shared google doc could help everybody interested share ideas ? Do you want to start one ?
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:
Did you check if that is not a simple interpolation ?
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 !
@Gkikas-LGPZ please check 0.8.2 that I have just published:
You probably need to specify the name as
email@example.com when loading it for now.
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.
Windy shows the meteogram at the picker (flag) location.
Températures match for near term forecasts.
