Greenhouse Effect & Energy Balance

អំពីការពិសោធន៍និម្មិតនេះ

Explore Earth’s incoming sunlight and outgoing infrared radiation. Change albedo and atmospheric absorption, then watch the surface warm or cool.

អ្វីដែលសិស្សអាចស្វែងរកបាន

  • Keep albedo fixed and increase infrared absorption. What happens before the new equilibrium?
  • One-layer teaching model: sunlight passes through the atmosphere; infrared absorptivity ε also sets emission. OLR=σT⁴(1−ε/2); absorbed sunlight=1361(1−albedo)/4 W/m². Atmosphere adjusts instantly; surface heat capacity is 10 MJ/m²/K. Clouds, convection, oceans and feedbacks are omitted. This is not a climate forecast.

សំណួរដែលគ្រូតែងសួរ

Keep albedo fixed and increase infrared absorption. What happens before the new equilibrium?

Less energy initially escapes to space, so the surface warms. Outgoing radiation rises until it matches absorbed sunlight at a higher temperature.
