For most of this year so far I have been working on the new dropsonde diagram. It replaced the previous Flash diagrams I had. The diagram has been available for months, but I finally got around to figuring out how to have popup windows when you hover your mouse over points. I still have more work to do on it eventually, but this is about all I might do on it for now, unless someone has some suggestions.

Example interactive diagram at the bottom of the page:

Screenshot of the example on that page:



The extra parts of the diagram are added by selecting:

"Show wind speed graph section"

And:

"Show hodograph"

Eventually I might make those default options and then I would have the diagram wider as well on load.

You can save a screenshot of the diagram to your computer easily as well by clicking the "Save Image" button.
