My biggest interest is in temperature versus altitude in the first 1KM to 1..5KM above the surface. This will let you know where the cap that might kill the day exists. I had started a project for this some years ago, and since the wind usually blows here in Kansas, I was looking to use a couple of kites to lift the package. It would always stay within the confines of the airport, and would have much lower recurring cost than a helium balloon. I would be intereted in a package that gets temperature and altitude either logged on board, or transmitted to a PC on the ground. And at $150 or so, I am very interested.
