WebSince hot fluids rise, this hot air may rise to the upper troposphere (near the tropopause). This rising air may cool, as we will discuss shortly. Since cool air sinks, air in the upper troposphere (near the tropopause) may sink to the lower troposphere (near mean sea level), where it may be warmed again thus causing it to rise again.

"Webof satellite ephemerides, effects of ionosphere and troposphere are almost eliminated by forming DD (double-difference) measurement equations. With a medium length baseline under 100 km, in particular ionosphere effects are hard to be canceled by DD. In this case, dual-frequency measurements are often used to eliminate the ionosphere effects. " - Ionosphere and troposphere delays
