More verbal description of EARTH-ATMOSPHERE ENERGY FLUX SYSTEM

Total SOLAR INPUTS: 100 Units of Shortwave Radiant Energy INPUTS of which:

- ABSORBED BY ATMOSPHERE:

3 Units absorbed of Ultraviolet radiation (converted to Heat) by Ozone

21 Units absorbed by atmospheric gases mainly Carbon Dioxide and Water (vapor, liquid and solid) MAINLY NEAR INFRARED portion of Solar Spectrum

- ABSORBED BY GROUND:

45 Units of Solar absorbed by ground (non-selective by wavelength)

- REFLECTION OF SHORT-WAVE RADIANT ENERGY: (TOTAL = 31 UNITS)

28 Units reflected from Atmosphere (especially by clouds = 21, diffuse reflection v& scatter = 7)

3 Units reflected from the earth

- TOTAL OUTPUTS (≈ 100 UNITS):

31 Units reflected from Atmosphere (28 units) and Earth (3 units)

8 Units emitted Long-Wave Radiation by Earth to Space

3 Units emitted Long-Wave Radiation by Stratospheric ozone layer to Space

58 Units emitted Long-Wave Radiation by Atmosphere to Space

•Total = 100 units
