anybody working on a trajectory plugin?

@mhaberler
I am REALLY interested in this. I fly a paramotor and am currently working on flying large FAI triangles (shortest side has to be at least 28% of the total triangle). I use different direction winds at different heights to improve my speed and thus distance I can do using the 22 litres of fuel I carry.Current favourite site is take off at Yass (Australia) in remnants of the easterly sea breese (up to 1500AGL) and fly NE then NW and then climb into the upper synoptic westerly (up to 8500 where there is controlled airspace) to do a W leg to return to Yass. Longest flight so far is 313km at average speed of 74kph.
Are you a JS developer? I have a developer background.
I'd be REALLY keen to incrementally develop a plugin. e.g. for a given location find times when there is a wind direction difference of more than 150 degrees in wind layers from surface to 10000 feet. And then add functionality
MANY people would be interested (aviation, balloons), nothing similar is available and the excellent people at Windy provide access to the best datasets.
Is anyone else interested in this? I'm happy to provide use cases if ant developer is interested in a project.

I know procedural programming languages reasonably well, but have next to zero JS skills. So my contribution could be usage, suggestions and maybe the occasional trivial fix.
That does not deter me from wishful thinking ;) - what trajectory viewers IMO are missing is the ascent and descent phase. So in my case that'd be:
-
forward and backward trajectories for a given location and altitude
-
refine with a ascent/descent rate for the takeoff and landing phase

tempting...
Cool project. If I get time, will give it a go.

I am very interested in your "traj" plugin.
With the EC model data no longer available (for the time being), is there any chance that you could integrate the GFS into your plugin instead (and until the EC data is hopefully available again).
Thanks

windy-plugin-traj@0.0.8

Thankyou very much for the plugin.
Here is a screen shot of your plugin at work......
As an example, this is a one hour projection of TS's over inland eastern US. I captured the TS/lightning at -60min and then using your plugin, projected the steering winds 600hpa/500hpa/400hpa trajectories from -60min for 60min.
And the result can be seen in the dark grey region showing lightning density at the end of the duration +60min.Pretty good result in my books.
I have a few other uses for this plugin wrt Volcanic Ash/frontal movement etc. So thanks again..

Very interesting! Thank you!How can I see the duration and the "start" button?
I think the dark grey window (at lower left) must relocated a little higher.
-
Thanks. Max duration now 24 hours, but I can make it longer if required.
The radar, lightning overlay has a different layout. If you select any other overlay, it should be visible. Will update when I have a chance.

@rittels
Thanks a lot.
I think that trajectory tool is also usefull for very short range forecast (up to 2 hrs)
for thunderstorm movement (by experience I use 700 hPa winds). -

@rittels
You are awesome! thx -
Thx for the update. Awesome plugin.
Maybe, just maybe, @ivo and his team could integrate this into the Windy platform.
What would I do without Windy!!!!

@stitch
Great idea!
I'd love to have it into the Windy platform
instead of running the plugin any time I need it. -
Yeah!! windy-plugin-traj@0.1.0 now working on ECMWF again.
Thx @ivo !!

@rittels said in anybody working on a trajectory plugin?:
windy-plugin-traj@0.1.0
Fantastic!
Hands down....best weather app - and just getting better.
-
Your traj plugin is working a treat.
Just one comment - is there a means of removing the trajectory traces from the panel without needing to refresh the Windy window and then resetting the plugin programs? The window panel gets rather busy with multiple traces overlaid on top of each other. It would be nice to be able clear the trace plots with a click of a button and start a fresh.
Thx
-
I have just noticed one issue with the Traj plugin....
when selecting the 100m level on the EC, the plugin gets set into a repetitive loop and the trace doesn't appear to be the correct path.
Sfc and all the other standard levels look fine.
-
try: traj@0.1.3
There is a discrepancy between the levels available with the dataLoader and on the site. 1000h is available with the dataLoader, which I took the liberty to represent as 100m on Windy UI (perhaps better to just leave it out). 250h also not available in dataLoader, as @vicb said earlier.
-
@rittels Thanks for this phenomenal job!
this is already very useful - will do a balloon ride tomorrow early morning and see how that fares relative to the plot!
If I may add a suggestion:
if you select several altitudes on the plot it is hard to discern which track belongs to which altitude
why not choose different colors for each track in the plot and color the altitudes in 'Select levels' accordingly?
