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...
Modelling deep convection and its impacts on the tropical tropopause layer
deep convection the tropical tropopause layer
2010/11/30
The UK Met Office's Unified Model is used at a climate resolution (N216, ~0.83°×~0.56°, ~60 km) to assess the impact of deep tropical convection on the structure of the tropical tropopause layer (TTL)...
Tracer measurements in the tropical tropopause layer during the AMMA/SCOUT-O3 aircraft campaign
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...
Variability of residence time in the Tropical Tropopause Layer during Northern Hemisphere winter
residence time Tropical Tropopause Layer Northern Hemisphere winter
2009/9/22
For the first time the long-term interannual and spatial variability of residence time (τ) is presented for the TTL between 360 K and 400 K potential temperature (~14 to 18 km altitude). The analysis ...
Estimating the contribution of bromoform to stratospheric bromine and its relation to dehydration in the tropical tropopause layer
bromoform stratospheric bromine dehydration tropical tropopause layer
2009/1/16
The contribution of bromoform to the stratospheric bromine loading is estimated using the one-dimensional tropical mean model of Folkins and Martin (2005), which is constrained by observed mean profil...
Diagnosis of processes controlling water vapour in the tropical tropopause layer by a Lagrangian cirrus model
processes controlling water vapour tropical tropopause layer Lagrangian cirrus model
2008/12/23
We have developed a Lagrangian air-parcel cirrus model (LACM), to diagnose the processes controlling water in the tropical tropopause layer (TTL). LACM applies parameterised microphysics to air parcel...
The CO2 tracer clock for the Tropical Tropopause Layer
CO2 tracer clock Tropical Tropopause Layer
2008/12/15
Observations of CO2 were made in the upper troposphere and lower stratosphere in the deep tropics in order to determine the patterns of large-scale vertical transport and age of air in the Tropical T...
The roles of convection, extratropical mixing, and in-situ freeze-drying in the Tropical Tropopause Layer
extratropical mixing in-situ freeze-drying Tropical Tropopause Layer
2008/11/24
Mechanisms for transporting and dehydrating air across the tropical tropopause layer (TTL) are investigated with a conceptual two dimensional (2-D) model. The 2-D TTL model combines the Holton and Get...
Characteristics of aerosol and cloud particle size distributions in the tropical tropopause layer measured with optical particle counter and lidar
cloud particle tropical tropopause layer optical particle
2008/11/12
An optical particle counter (OPC) is used in conjunction with lidar measurements to examine the characteristics of the particle size distribution in cirrus cloud in the tropical tropopause layer (TTL)...
Long-term climatology of air mass transport through the Tropical Tropopause Layer (TTL) during NH winter
Long-term climatology mass transport Tropical Tropopause Layer (TTL) NH winter
2008/10/30
A long-term climatology of air mass transport through the tropical tropopause layer (TTL) is presented, covering the period from 1962–2005. The transport through the TTL is calculated with a Lagrangi...
