anybody working on a trajectory plugin?
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
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).
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.
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).
Fixed the box: email@example.com
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!!!!
I'd love to have it into the Windy platform
instead of running the plugin any time I need it.
Yeah!! firstname.lastname@example.org now working on ECMWF again.
Thx @ivo !!
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.
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.
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?
quality check.. this looks VERY usable - congratulations! @rittels
