anybody working on a trajectory plugin?

like @Gkikas-LGPZ , I generally refer to 700hpa/600hpa as a mean steering wind. But then in northern Aust the summer Tstorms top out in the mid 30k ft to mid 40k ft levels.
With respect to southern Aust winter Tstorms, then I generally lower the TS tops to mid 20k to 30k ft level and would then look a the 800hpa and 700hpa levels.
You can see what the forecast CB tops are using "Cloud tops" (just ensure the model is highlighting cellular based clouds and not layered clouds like cirrostratus/altostratus etc).
I see you have used the radar/lightning window to correlate the Tstorm speed/motion to a wind height field - this is what I would do as well.
Be wary though of Tstorms that move/turn towards a different directions opposing the mean or normal Tstorm tracks (these anomalous movers could potentially turn into the severe variety of Tstorm).There is no steadfast rule....just trial an error.
All the best with your forecasting ..... @mhaberler

@stitch thanks, really helpful!
once in a while we have a TS nearby at an event and it is unclear wether we can go for a launch or not; the traj feature helps narrow down the question

@rittels 0.2.0 feedback:
exported trajs now carry over a color - great!
the gpsvisualizer.com Atlas import snag is gone.
here is a traj gpx export example, warped into kml with these gpsvisualiser KML settings
:
I think export is just fine now.
Since my birthday's coming up... how hard would it be to play traj's from different models?

stunning: all pressure levels exported, imported with gpsvisualizer to produce KML
have a look in Google Earth!

easy: 0.2.1
just set the model at the bottom and the plugin will use it. Not sure if all the products are supported by the dataloader.

@rittels GFS definitely works, ICON - need to re-check, NEMS seems not to work
perfect!
my last suggestion is already down to usability: append the model name to the export file basename, and each track's name after pressure - then clicking the traj in GE will also report the model, not just pressure; less confusion potential when comparing several model results
Herewith I've run out of suggestions!

GFS, ECMWF and ICON works very well
NEMS, AROME - no output(IMO not an issue and I dont suggest putting energy into resolution)

@rittels we might have serious test material shortly
I am attending the Sagrantino Cup from July 26 to Aug 4th, and there should be 50+ hot air balloon teams there
there should be 2 flights daily, so that should yield hundreds of tracks in different altitudes
I will prepare and publish trajectories twice daily for each takeoff location and ask the teams to share their GPS tracks with me
-
@mhaberler Wow, that looks amazing.

Giving ideas!
I don't know if its possible to include sea currents in trajectories plugin.
It would be very helpful for tracking (lost) floating objects and oil spills
(in case of ship accident).
Of course, I understand that it will be an experimental product
as sea currents data are not updated very often. -
... for rubber ducks, also! 😊

Great idea, but don't think the plugin DataLoader contains current data. Possible with the interpolator though. Will try...
Rubber ducks!! 😂

@rittels
They "pay 100 EUR/duck for the person who find it." 🤣 -
@Gkikas-LGPZ my ISP career has taught me to stop when done.. which I do here - I am all for single-feature-well-done tools and less so for feature creep
But I guess someone interested in sea currents could take traj as a an example and base to work from
-
@rittels works fine - all relevant info carried over!
thanks for jumping that many hoops so far!

I just found an interesting feature - incidentally very useful:
-
do a trajectory for some future point in time and just let the window sit (do not clear)
-
hit 'Start' again once a new model run becomes available
-
since the old trajectory is not erased, both (or all) are shown together on one screen - i.e. you can immediately judge how the wind forecast changes over successive model runs
That is super useful for Alps crossings - we need something between 340 deg NW and 10 deg NE to make it across quickly enough and still hit the Po valley
since usually such a crossing is planned days in advance (like 5) the trend in forecast changes is essential even if things looked good initially

nice animations made possible with the traj plugin:
