31.   In turn, the dark bark on trees absorbs more solar radiation.

32.   Many complex factors affect climate, from the oceans and atmosphere to solar radiation and the chemical reactions of greenhouse gases.

33.   Myneni and his co-researchers, following a different method, analyzed changes in solar radiation absorbed by plants as they perform photosynthesis.

34.   Once aloft, the platforms would beam back reams of data each day on everything from solar radiation to the growth of plankton beneath ocean surfaces.

35.   Only when they swing near the Sun, where solar radiation boils off gas and dust, do comets light up.

36.   Solar radiation then may be mistaken by a receiving dish on the ground for a communication signal.

37.   Solar radiation may be mistaken by a receiving dish on the ground for a communication signal.

38.   Stratospheric ozone is essential in protecting humans from carcinogenic ultraviolet solar radiation.

39.   Soot is dark, and absorbs solar radiation.
