Hi, Len. There's no way you can get accurate experimental results for less than obtaining a cheapie light meter on eBay.

Cheers Chris

I'll second the light meter idea. If it's a good one, be sure to use the "incident light" mode (with a little white bubble over the sensor) and point it at the sky instead of the subject/target. If it's a cheapie, you can probably make your own diffuser instead of the white bubble.

Note that the relation between sun intensity and the temperature of air or any target is also dependent on time and thermal conductivity, and with air there are also the issues of wind speed and humidity.

If you can explain exactly what you are trying to do, someone here can probably give specific advice.

You have to do it multiple times, noting the sun intensity and temoerature.
