In response to this, aerosols indirectly increase the probability of absorption. Sulfite is a vital biochemical element that is found in our atmosphere as well. Its primary sources are from volcanic emissions, sulphur in microorganisms and sea salt returning to the geosphere through sedimentation. Algae transfer between 20 and 50 million tonnes of sulphur from the oceans to the atmosphere each year, while human activity only accounts for 80 tonnes. Sulfur clouds can block solar radiation naturally, as well, by volcanic explosions.
Clouds are the most significant influence on solar radiation.
Cloud droplets are larger than aerosol particles and scatter radiation mostly by diffusion. The quantitative influence of clouds on solar radiation is dependent on solar elevation, the thickness of the cloud, the size and distribution and amount of liquid water in the cloud. Charlson's original idea in 1987 was that ocean waters would be heated by greenhouse gases and would encourage algal production. He and his associates hypothesized that an increase in DMS would increase the sulphate aerosol and would therefore increase cloud formation and albedo, which would reduce global temperature, marine algal productivity and DMS emissions. Carbon Storage Oceans absorb the largest fraction of solar radiation on Earth because of their great area and low albedo.
