(~10 km altitude) 04/09/03 12.540 Lec 15 4 Troposphere • Lots of examples of web-based documents about the atmosphere: See for example. http://www-das.uwyo.edu/~geerts/cwx/notes/chap01/tropo.html • Tropopause is where temperature stops decreasing. Generally at pressure levels of about 300 mbar but can be as low as 500 mbar. • only about 70% of delay. • Generally by height of 50-100km all of atmospheric delay accounted for. • Troposphere is where weather systems occur and aircraft fly on the tropopause. Sometimes term “tropospheric delay” used but this is 2
