Thanks guys. It's been a lot of fun to develop. The composite RADAR images are only new. I made a vortex following composite RADAR subset as well, I'll send the link through when the next cyclone fires up, it looks pretty cool!
Richard, I've also noticed that the Sydney sounding doesn't show up. I've got no idea why, but it doesn't seem to appear on the University of Wyoming's website where I source the data from, but I'll double check to make sure it isn't a mistake that I've made.
Cheers,
Dave
