Interesting stuff. Things like tarmac heat's influence on adjacent air temperatures are often taken for granted in the absence of the real world variables like those mentioned above. A simple measurement of external air temps at different heights taken on a moving vehicle and compared to static temperatures at the same heights would shed light. I'd be curious, but even then results would only be applicable to the conditions in that place on that given day.

Mike, I understand that you don't want to get into details and technicalities about your build at this time, but it's very intriguing stuff and people will naturally want to see and hear more (myself included). I hope you change your position on sharing more thoughts, details and photos.
