another online prediction tool
toggle quoted messageShow quoted text
That is kind of what I did with my GPSL predictions only manually. I always ran 6 predictions, 60K, 90K & 105K burst 1100FPM & 850FPM Asc/desc. Then for good measure I would add the habhub prediction as a test.
I have been thinking about adding a way in my tool to automatically run the multiple runs but never got around to it. My tool never really caught on so haven't spent much time on it.

So I wonder if we could create a good landing zone prediction by varying the ascent rate and burst altitudes by plus or minus some percent. Say 10%. Then use a combination of these variations to map out a recovery ellipse (I assume it would an ellipse shape with the major axis aligned along the overall flight path).

Word from the other side of the pond:-
The Mancunian Balloonian project at the University of Manchester UK ( http://manseds.co.uk/index.html ) have been using the API to the Habitat predictor to do Montie Carlo runs varying flight parameters to get a similar heat map output - see https://www.youtube.com/watch?v=9tVPAtmtc7w
The Habitat predictor holds the GFS world data in RAM - consequently it’s quite quick.
The Southampton predictor has been around for 3 - 4 years. I’ve used it a few times - the heat map output is cool and its seems well thought out (the theory is extensive). The user interface is reasonably intuitive and quite easy to use. However the few times I’ve used it I haven’t found the results more accurate than Habitat, on the downside its much slower (I suspect they hold the GFS data on disk).
