Insight from ozone and water vapour on transport in the tropical tropopause layer (TTL)
ozone and water vapour the tropical tropopause layer (TTL)
2011/1/19
We explore the potential of ozone observations to constrain transport processes in the tropical tropopause layer (TTL), and contrast it with insights that can be obtained from water vapour. Global fie...

Stratospheric water vapour budget and convection overshooting the tropopause: modelling study from SCOUT-AMMA
Stratospheric water vapour the tropopause SCOUT-AMMA

Tracer measurements the tropical tropopause layer the AMMA/SCOUT-O3 aircraft campaign
2010/8/12
We present airborne in situ measurements made during the AMMA (African Monsoon Multidisciplinary Analysis)/SCOUT-O3 campaign between 31 July and 17 August 2006 on board the M55 Geophysica aircraft, ba...
Ice nucleation and cloud microphysical properties in tropical tropopause layer cirrus
Ice nucleation cloud microphysical properties tropical tropopause layer cirrus
2010/2/21
In past modeling studies, it has generally been assumed that the predominant mechanism for nucleation of ice in the uppermost troposphere is homogeneous freezing of aqueous aerosols. However, recent i...
Aerosols that form subvisible cirrus at the tropical tropopause
Aerosols subvisible cirrus tropical tropopause
2010/1/18
The composition of residual particles from evaporated cirrus ice crystals near the tropical tropopause as well as unfrozen aerosols were measured with a single particle mass spectrometer. Subvisible c...
