Document Summary
1. 23. 12: solar system formation, inner planets, sun, insolation, solar radiation, rotation, revolution, subsolar point, solar constant, season, axial tilt, axial parallelism, sphericity, subsolar point, tropics of cancer/capricorn, arctic/antarctic circles, solstice/equinox, midnight sun. -not really constant, but an average of 1372 w/m2. -insolation at the top of the atmosphere: solar radiance that reaches the earth"s atmosphere and surface. -watt(w)=1 joule/sec how much energy over time. -m2=meters2=area how much energy over an area. -picture: earth"s atmosphere as seen from the international space station. Leap year- every 4 years: elliptical orbit. Point on the earth at some location that sun is directly above earth; moon is 90 above sun: equator 0 in blue, 0 (least energy--winter) and in red (most energy--summer) January --(north hemisphere is winter and southern is summer); antarctic is receiving 24 hours of light (midnight sun) and receiving the most energy: april at an equinox.
