What is the relationship between o2 and CO2 in the atmosphere?
The concentration of oxygen in air is about 500 times higher than CO2, but oxygen is about 50 times less soluble. For both gases the concentration is lower at higher temperatures. As the temperature increase the availability of CO2 decreases faster than that of oxygen.
What is the relationship between CO2 and infrared energy?
Carbon dioxide, for example, absorbs energy at a variety of wavelengths between 2,000 and 15,000 nanometers — a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions.
How are the numbers of infrared photons coming back to earth related to the concentration of greenhouse gases explain why?
As the concentration of greenhouse gases are increased, more of Earth’s electromagnetic infrared radiation is absorbed by the atmosphere, making the atmosphere warmer. A warmer atmosphere radiates more effectively, resulting in an increased re-radiation of infrared photons from the atmosphere to Earth’s surface.
How much infrared radiation does CO2 absorb?
The range of infrared radiation from Earth is 6 to 22 microns. Each greenhouse gas and water vapor absorbs radiation from different areas of the electromagnetic spectrum. Carbon dioxide and water absorb long wave radiation from 12 to 19 microns. Methane absorbs wavelengths 6 to 8 microns.
What is the proportion of carbon dioxide in atmosphere?
CO2 makes up only about 0.04\% of the atmosphere, and water vapor can vary from 0 to 4\%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed.
What is 25\% of the greenhouse effect?
They estimated that water vapor accounts for about 50\% of Earth’s greenhouse effect, with clouds contributing 25\%, carbon dioxide 20\%, and the minor greenhouse gases and aerosols accounting for the remaining 5\%. In the study, the reference model atmosphere is for 1980 conditions.
What is the effect of infrared photon on the different atmospheric gases?
Since the temperature of a gas is a measure of the speed of the molecules in the gas, the faster motion of a molecule that eventually results from the IR photon that was absorbed by a CO2 molecule raises the temperature of the gases in the atmosphere.
How much energy can CO2 absorb?
In fact already 95\% of the radiant energy is absorbed by CO2 at pre-industrial levels leaving a maximum of just 5\% for any increase you like.
What wavelength does CO2 absorb?
It has a long lifetime in Earth’s atmosphere. Carbon dioxide strongly absorbs energy with a wavelength of 15 μm (micrometers). This makes carbon dioxide a good absorber of wavelengths falling in the infrared radiation region of the spectrum.
