Android Skew-t app

This is a very worthwhile effort. I get a very readable graph if I turn my Nexus 7 horizontally, set 'low altitude display' and zoom in 2X. That makes the fonts big enough to read easily and displays the altitude of interest (up to about 10K for me). And it allows me to see the wind speed graph at the same time.



The 'time warp' slider is informative and helps to get a feel for how conditions change through the day.



Here are some not necessarily good ideas off the top of my head:



It might be useful to have the option to set surface temperature automatically based on forecast.



For eastern pilots,it might be useful to have the option to display the data to top of 10K, but only if you also had the option to choose a larger font.



It might be useful to display a user-defined vertical line in the wind graph.



It might be useful to display a small circular surface wind direction indicator.



It might not be useful, but I'm curious what one would see if you implemented a 'geographic position' slider, to for example incrementally change the ground position upwind while keeping time constant.



Also somewhat outside the scope of your project, I like to look at how cloud cover is predicted to change through the day.


flub, there is already a site that does all your 'useful' functions splendidly:
http://www-frd.fsl.noaa.gov/mab/soundings/java/

You can load it on your Nexus through any browser. I think the Android app is just fine in displaying a limited subset of that data.
Many thanks Alan, very nice app you put together.

FYI. One reason I wrote this app is my Nexus-7 doesn't have a supported java plugin so you can't load the noaa site.

I do agree that I want to keep this app simple but functional.

Thanks for all the testing and feedback everybody has given me.

I've just posted a new fix.
- The ground level reading in now included in the graph
- Airport ID's with numbers are allowed.

I'm working on adding different data sources which will allow global use.

What do you think about adding support for waypoint files? You could then use waypoint names as an alternative to Airport ID.

I personally would love to see easy support for other models. For me, it wouldn't be a "set and forget" thing. I regularly consult different models to get an idea of consistency across them.

Nice job, by the way!

This might be making work for myself :-).

Would it be useful to overlay two (or more) models onto the same graph? If I did that cleanly would it now be a set & forget setting?

I think that would be a cool option

Alan,
Thanks a lot. It works like charm for where I am. I especially like the moving graphics.
Is there a way we can get some forecasting, like one or two days? Right now I can only get the current day.

Hi All,
Snip, Snip

As a recently licensed pilot I decided it would be a good idea to learn more about soaring weather prediction, specifically the workings of a Skew-t graph.



I published by first Android App.

I hope many of you find this useful.



I welcome your suggestions for improvements. As I said, this is new to me.



Enjoy.

I have different data sources mostly working, it just needs a bit more testing.

After that I want to add
* Named favourites (or something similar)
* Underlaying secondary model
* Extended range forecasting

For your enjoyment,

The newest version (uploaded 5 mins ago), can now show future data, not just today's data. Obviously this is only if the weather model supplies the needed data.

Also I have added a "Here" mode that uses your devices GPS to seed the lat/long.

Next I want to add support for waypoint files.

Any other requests or feedback welcomed.

Alan

Alan, you must be having fun with this!
Thanks,
Jim
