1914 Monthly Weather Rev. (U.S.) 42 151/1 This is true in general at those levels which are tropospheric over a station with high pressure, and stratospheric over another with low pressure.

1939 Proc. IRE 27 634 It is believed that most of the tropospheric reflections occur at air-mass boundaries or other similar discontinuities.

1973 Guardian 18 May 18/5 With tropospheric fallout there is a steep rise in the level of iodine 131 in milk.

2004 Times (Nexis) 6 May This lack of tropospheric warming has long puzzled scientists, as it is predicted by all the major models of climate change.

Compounds

tropospheric scatter n. = troposcatter n.; frequently attributive.
