That's a total decline of up to18 watts per square meter, out of the200 watts per square meter or so that reaches the earth's surface.

这表明森林通过降低地表反射率和表面温度,不仅增加地表净辐射,而且减少其用于感热和土壤热通量的消耗。
It is showed that the forest can not only increase net radiation but also decrease sensible and soil heat fluxes by decreasing surface reflectance and temperature.
