Hello,
I’m Emma Järvinen, an associate professor in physics at Tampere University. My research explores how tiny particles in the atmosphere - from soot to ice crystals in clouds - scatter and absorb light, and what this means for our climate.
My group develops optical instruments and uses them in laboratory experiments and atmospheric measurements. We investigate ice clouds, develop new ways to measure light absorption by soot-containing particles, and explore how these measurements can help satellites better observe clouds and airborne particles.
I also lead CRYSTAL, a project funded by the European Research Council (ERC), investigating how the fine details of ice crystal surfaces affect the way they scatter light.
Beyond our research, these measurement technologies are being commercialised through our startup company, schnaiTEC Oy, making them available to a wider community.
My research topics
Ice clouds & climate
Ice crystals are more than perfect snowflakes. In our ERC-funded project CRYSTAL, we study how tiny details on their surfaces change the way they scatter light, and what this means for ice clouds and climate.
Cloud polarimetry
How do cloud particles change the light that reaches our satellites? Our Hyper Angular Cloud Polarimeter (HACP) measures how particles scatter and polarise light, helping us better understand what satellites see.
Combustion particles
Soot particles absorb light and warm the atmosphere. We develop photoacoustic instruments that use sound to measure this absorption, helping us understand particles from combustion and their effects on climate.
