Ozonosphere temperatures under radiation equilibrium.

In two previous papers (Gowan 1928, 1930) calculating the effect of ozone on the temperature of the upper atmosphere, the height of the centre of gravity of the ozone layer was assumed to be about 45 km. Later, more reliable measurements were made (Gotz, Meetham & Dobson 1934) lowering this figure to 22 km., and also supplying the vertical distribution up to a little beyond 45 km. The results of the necessary revision of calculations were given to the Oxford Conference on Atmospheric Ozone (Gowan 1936). Strong (1939) and Summerfield (1941) have given a revision of the infra-red absorption of ozone and have taken the pressure into account. Elsasser (1942) and Dobson (1942) have discussed the absorption of water vapour in the atmosphere and Elsasser has justified the use of the square-root law for the pressure effect throughout the atmosphere for this vapour in the infra-red. The present paper gives the results of a further revised calculation making use of the new data, for latitude 50° N.
