This must be proportional to the number of particles in the slice, which is (N/V) adz and also proportional to the intensity of the beam I(z)dω. 47) On the right the product (N/V) adz × σ 0 may be interpreted as the total area with which the incoming beam interacts. Then I(z)dω may be interpreted as the number of photons impinging. Their product, the right-hand side of Eq. 47) would represent the decrease of intensity of the beam, which corresponds with the left hand side. Consequently σ 0 may be interpreted as the cross section of the particles in the slice.
7. 2 shows the solar absorption by the important pigments of several photosynthetic organisms. All the light energy absorbed by the pigments can be used for photosynthesis. For comparison the solar spectrum as it enters the top of the atmosphere is shown. 2), but the message remains that the pigments shown absorb in important parts of the spectrum. Chlorophyll-a, the major pigment of higher plants, algae and cyanobacteria, absorbs red and blue light. In combination with carotenoids such as β-carotene they provide plants with their typical green colour.
From the logarithmic scale it is obvious that at the lower wavelengths the increase in irradiance going from C to A is considerable. Predictions from models for atmospheric ozone production and breakdown indicate a stratospheric ozone depletion ranging from 5–20% due to CFC and N2 O production. 8 one may predict that a 10% ozone depletion would result in a 45% increase in effective UV-B radiation. These alarming numbers illustrate the necessity to monitor the structure of the ozone layer accurately and to quantify the effects of increased UV on living organisms.
