Variability in HDO/HâO abundance ratios in the tropical tropopause layer
The dehydration of air in the tropical tropopause layer (TTL) and mechanisms for the entry of water vapor into the stratosphere are investigated by an analysis of ACE-FTS...- publication PDF

Shapes and Fall Orientations of Ice Particle Aggregates
Testing the often-made assumption that ice particle aggregates (snowflakes) are well represented by oblate spheroids, ellipsoid fits are applied to aggregate images. An...- publication PDF

On the occurrence of hollow bullet rosette- and column-shaped ice crystals...
Cirrus clouds in mid- and high latitudes are frequently composed of bullet rosette- and column-shaped ice crystals, which can have hollow ends. Bullet rosette-shaped ice...- publication PDF

Eddy covariance VOC emission and deposition fluxes above grassland using PTR-TOF
Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution...- publication PDF
