GEOG 1216 Lecture Notes - Subsolar Point, Daytime, Solar Irradiance

All of the following is true in regard to the earth's radiation balance except?

(a) at around 35°, incoming insolation is roughly balanced with outgoing longwave radiation.

(b) poleward of 35° regions emit more outgoing longwave radiation than they receive as insolation.

(c) outgoing longwave radiation increases poleward in regular increments, peaking at the poles.

(d) Equator, tropics, and subtropics receive more insolation than what they emit as outgoing longwave radiation.

In polar areas, solar radiation strikes Earth at a _____.

small angle

large angle

right angle

greater angle than at the tropics

The intensity of electromagnetic radiation from the sun reachingthe earth's upper atmosphere is (1.37 kW/m^2). Assuming an averagewavelength of (680 nm) for this radiation, find the number ofphotons per second that strike a (1.20 m^2) solar panel directlyfacing the sun on an orbiting satellite.
