I'm Emma Järvinen - a researcher in the field of atmospheric sciences. Currently I am working in the field of cloud physics. My current research interest lies in ice crystal optical properties, cirrus clouds, airborne measurement technologies and developing state-of-the-art optical measurement techniques. I have participated in several aircraft campaigns in the past and will continue my work in future field studies. Currently, I'm working as a Helmholtz Young Investigator Group Leader at Karlsruhe Institute of Technology (KIT) in Karlsruhe, Germany.
My research topics
Ice clouds cover daily Earth's surface. But what do we know of the atmospheric ice particles? In situ measurements offer valuable information on the ice particle microphysics and are important for validating remote sensing observations.
When it comes to ice particles, many of us think of perfectly shaped hexagonal crystals. In reality ice crystals have all sorts of microscale structures that can have significant consequences for our climate.
Mixed-phase clouds consist of ice crystals and water droplets that co-exist. Detecting ice among droplets is challenging. Occasionally large number of small ice crystals are observed at relatively warm clouds just below freezing point.
