The net radiation measured over a dense forest in Naitasiri at noon on a cloudless June day was 730 Wm-2. Given the following other measurements made over the forest, calculate the temperature of the top of the forest canopy, assuming that the foliage radiated like a perfect black body.
Downward solar radiation 900 Wm-2 Albedo 0.10 (10%)
Downward longwave radiation 400 Wm-2
(HINT: Stefan’s Law B = σT4 where σ is 56.7 × 10-9 Wm-2K-4, and T is the temperature in degrees Kelvin.)
