1924 S. N. Sen in Q. Jrnl. Royal Meteorol. Soc. 50 29 Up to an approximate height of 8 km. above the ground the air density is chiefly controlled by the temperature. The name ‘thermosphere’ is proposed to denote this layer of the atmosphere.

b. The part of the atmosphere between the mesopause and the height at which it ceases to have the properties of a continuous medium, characterized throughout by an increase of temperature with height.

1950 S. Chapman in Jrnl. Geophysical Res. LV. 396 I propose the name..thermosphere for the layer of upward increasing temperature above that level [i.e. of the mesosphere].

1981 Sci. Amer. July 46/3 On the earth the thermosphere is present day and night; the large-scale rotation of the atmosphere with the planet carries the heated day-side upper atmosphere to the night side of the planet. On the night side of Venus, however, the thermosphere disappears.

2. The warmer, upper part of the oceans.

In the following the terms thermosphere and psychrosphere are used for these divisions to stress this salient ecological factor.
