Solved in 2 steps
- Long-wave solar radiation is more energetic than short-wave solar radiation. True FalseOf the total incident solar radiation what is the proportion of PAR?The greenhouse effect in the atmosphere is produced due to: 1.Absorption and re-emission of infrared radiation by the atmosphere 2.Absorption and re-emission of ultraviolet radiation by the atmosphere 3.Absorption and re-emission of visible light by the atmosphere 4.Absorption and re-emission of visible light by clouds
- As solar Rays hits the earth,they are either reflected,transmitted or absorbed by the cloud systems in the atmosphere..true or falseThe ultraviolet solar radiation easily penetrates the cloud system , but the re-radiated infrared waves in the form of heat are trapped for a variable time in the cloud systems .. true or falseThe current concentration of CO2 in the atmosphere is about 415 ppmv. It has been estimated that annual anthropogenic additions to the atmosphere are about 30 gigatonnes (Gt), of which about 15 Gt are removed into oceans and the terrestrial environment. a) Use these values to estimate the yearly net increase in atmospheric carbon dioxide mixing ratio, in ppmv. (note that 1 Gt = 1015g)
