Observations of temperature, winds, and atmospheric trace gases suggest that the transition
from troposphere to stratosphere occurs in a layer, rather than at a sharp “tropopause.” In the …

Ozone depleting substances (ODSs), listed in the Annexes to the Montreal Protocol (1987),
are manmade chemicals emitted into the atmosphere that deplete the stratospheric ozone …

Ice clouds in the tropical tropopause layer play a key role in dehydrating air as it enters the
stratosphere,. However, in situ measurements show that water vapour within these clouds is …

The T-matrix method is one of the most powerful and widely used theoretical techniques for
the computation of electromagnetic scattering by single and composite particles, discrete …

We present results of Lagrangian troposphere‐to‐stratosphere transport (TST) in the tropics
based on trajectory calculations for the period 1979–2001. The trajectories and …

Although it is well known that air enters the stratosphere preferentially through upwelling in
the tropics, the exact mechanisms of troposphere-to-stratosphere transport (TST) are still …

Subvisible cirrus (SVC) clouds are often observed within the tropical tropopause layer (TTL).
Some studies suggest that SVC has a significant impact on the earth radiation budget. The …

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 …

In-situ ice crystal size distribution measurements are presented within the tropical
troposphere and lower stratosphere. The measurements were performed using a …

There are a couple of reasons to stimulate a discussion about the definition of clouds. One
reason is that the American Meteorological Society (AMS) and the World Meteorological …
