Hi all, I have searched the internet for hours and have come up empty. Perhaps I'm just not entering the correct search terms. What I would like to work out is variation of temperature (in air) with altitude above the fire. Details: The fire is a bushfire (a quick search suggests a temperature of 1200C) Atmosphere temperature being 25C Altitude above fire 120m Any ideas how I would go about this task? A rough temperature will be fine. Thanks for reading!
