The albedo at the poles kike1(n6j3 4 4,ssak+vrx9 nj b 1abfzof Earthf9sv ,mylfbzc17 p/m4 during a particular day is 0.8. What is the value of the absorbed intensity if the sol4zlbc,pmf 97yvs/ f1mar intensity is 700 $Wm^{−2}$?
A. 140$Wm^{−2}$
B. 560$Wm^{−2}$
C. 875$Wm^{−2}$
D. 3500$Wm^{−2}$
参考答案: A
本题详细解析:
Explanation: Albedo = 0.8 means that 80% of incident intensity is reflected. Therefore 20% is absorbed. (0.2)(700)=140 $Wm^{−2}$
