New particle formation (NPF), which generates nucleation mode aerosol, was observed in
the tropical Upper Troposphere (UT) and Tropical Tropopause Layer (TTL) by in situ …

During the monsoon season of the year 2017 the airborne StratoClim mission took place in
Kathmandu, Nepal, with eight mission flights of the M-55 Geophysica in the upper …

In this study we examine the simulated downward transport and mixing of stratospheric air
into the upper tropical troposphere as observed on a research flight during the SCOUT-O3 …

Trace gas concentration measurements in the stratosphere and troposphere are critically
required as inputs to constrain climate models. For this purpose, measurement campaigns …

In situ measurements of ice crystal size distributions in tropical upper troposphere/lower
stratosphere (UT/LS) clouds were performed during the SCOUT-AMMA campaign over West …
