Chemical asorb sun energy?high CO2 in atmosphere

  1. Apr 4, 2006 #1
    good day to everyone,

    i wish to ask what chemical in our enviroment asorb some energy from sun?

    and what it has to do with high C02 level in the atmosphere?

    thanks in advance

    All chemicals in the environment absorb some energy from the sun.

    I assume you are referring to the greenhouse effect.

    Understand?

    What country are you from?

    True, but generally speaking the atmosphere is relatively transparent to incoming solar radiation (which falls mostly in the UV to visible range). Though, some chemicals such as ozone (0_3), certain aerosols, certain hydrocarbons absorb/scatter efficiently over certain bands, most shortwave radiation travels through the atmosphere unaltered until it reaches the surface. The exception being on cloudy days since clouds tend to scatter and reflect throughout most of the solar spectrum (that is why they look white).

    Previously, we had assumed a simplified model of Earth; one in which our planet had not atmosphere. This allowed us to examine the basic effects of albedo, latitude, and seasons on our planet's overall average temperature. We'll now add the atmosphere into our figuring; this will complicate matters, but will also make our model more realistic. We will just take a basic look at the atmosphere's influence on incoming solar radiation; we won't discuss winds and circulation patterns at this point.
