Hi Ben, Here is a link to a few of the sites that you requested. UWYO ( University of Wyoming ) is probably the most interesting and days can be lost exploring it & fiddling with the online tools. I import the text data into Soarcast (free) to generate a temp trace with cloud heights. Digital Atmosphere is another interesting program as it allows you to generate traces using data from multiple sonde sites, the downside is that it quite complex to use, albeit powerful once you get the hang of it.
