Impact of deep convection in the tropical tropopause layer in West Africa: in-situ observations and mesoscale modelling
deep convection the tropical tropopause layer West Africa in-situ observations mesoscale modelling
2011/1/19
We present the analysis of the impact of convection on the composition of the tropical tropopause layer region (TTL) in West-Africa during the AMMA-SCOUT campaign. Geophysica M55 aircraft observations...
Vertical transport rates and concentrations of OH and Cl radicals in the Tropical Tropopause Layer from observations of CO2 and halocarbons: implications for distributions of long- and short-lived chemical species
Vertical transport rates OH and Cl radicals the Tropical Tropopause Layer long- and short-lived chemical species
2010/8/16
Rates for large-scale vertical transport of air in the Tropical Tropopause Layer (TTL) were determined using high-resolution, in situ observations of CO2 concentrations in the tropical upper troposphe...
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...
Annual cycle of ozone at and above the tropical tropopause: observations versus simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Annual cycle tropical tropopause Chemical Lagrangian Model Stratosphere CLaMS
2010/1/18
Multi-annual simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) were conducted to study the seasonality of O3 within the stratospheric part of the tropical tropopause layer (TT...

High-resolution water measurements from three tropical airborne missions in Northern Australia, Southern Brazil and West Africa in different seasons are analysed to study the transport and transformat...
Diagnostics of the Tropical Tropopause Layer from in-situ observations and CCM data
Diagnostics Tropical Tropopause Layer in-situ observations CCM data
2009/12/31
A suite of diagnostics is applied to in-situ aircraft measurements and one Chemistry-Climate Model (CCM) data to characterize the vertical structure of the Tropical Tropopause Layer (TTL). The diagnos...
The representation of the Tropical Tropopause Layer (TTL) in 13 different Chemistry Climate Models (CCMs) designed to represent the stratosphere is analyzed. Simulations for 1960–2005 and 1980–2100 ar...
Any theory of water vapor in the tropical tropopause layer (TTL) must explain both the abundance and isotopic composition of water there. In previous papers, we presented a model of the TTL that simul...
