2011/2/25
Data from the Atmospheric Infrared Sounder (AIRS) on the EOS Aqua spacecraft each day show tens of thousands of Cold Clouds (CC) in the tropical oceans with 10 μm window channel brightness temperature...
Insight from ozone and water vapour on transport in the tropical tropopause layer (TTL)
ozone and water vapour the tropical tropopause layer (TTL)
font style='font-size:12px;'>
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...

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)...
Correlating tropospheric column ozone with tropopause folds: the Aura-OMI satellite data
tropospheric column ozone tropopause folds the Aura-OMI satellite data

The geographic and temporal variations in tropospheric and stratospheric ozone columns from individual swath measurements of the Ozone Monitoring Instrument (OMI), on the NASA Aura spacecraft, are rea...
Stratospheric water vapour budget and convection overshooting the tropopause: modelling study from SCOUT-AMMA
Stratospheric water vapour the tropopause SCOUT-AMMA
font style='font-size:12px;'>
2010/9/14
The aim of this paper is to study the impacts of overshooting convection at a local scale on the water distribution in the tropical UTLS. Overshooting convection is assumed to be one of the processes ...

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
font style='font-size:12px;'>
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 ...

2009/5/6
In this study backward trajectories from the tropical lower stratosphere were calculated for the Northern Hemisphere (NH) winters 1995–1996, 1997–1998 (El Niño) and 1998–1999 (La Niña) a...
Ultrathin Tropical Tropopause Clouds（UTTCs）：I. Cloud morphology and occurrence
Ultrathin Tropical Tropopause Clouds UTTCs Cloud morphology
font style='font-size:12px;'>
2009/3/11
Subvisible cirrus clouds (SVCs) may contribute to dehydration close to the tropical tropopause. The higher and colder SVCs and the larger their ice crystals, the more likely they represent the last ef...

2009/2/11
In this study the global lapse-rate tropopause (LRT) pressure, temperature, potential temperature, and sharpness are discussed based on Global Positioning System (GPS) radio occultations (RO) from the...
Ice supersaturations exceeding 100% at the cold tropical tropopause: implications for cirrus formation and dehydration
Ice supersaturations cold tropical tropopause cirrus formation dehydration
font style='font-size:12px;'>
2009/2/7
Recent in situ measurements at tropical tropopause temperatures as low as 187 K indicate supersaturations with respect to ice exceeding 100% with little or no ice present. In contrast, models used to ...
Estimating the contribution of bromoform to stratospheric bromine and its relation to dehydration in the 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...
