Florian Sedlmeir and Hannah Kessenich presented Tuwhiri’s work at the European Geosciences Union General Assembly, held in Vienna from 3 to 8 May 2026.

Florian presented , the instrument side of the programme — how a whispering-gallery-mode resonator converts faint atmospheric signal into optical light that ordinary photonics can measure.

Hannah presented , which addresses the other end of the problem: what you do with the measurements once you have them, and how to describe the behaviour of the ozone hole in terms that a forecasting model can use.

The EGU General Assembly is the largest geosciences meeting in Europe, drawing around 20,000 researchers across the Earth, planetary and space sciences. For a programme that sits between instrument development and atmospheric science, it is a useful place to be heard by both communities at once — and to test whether the case for a low-cost limb sounder lands with the people who would use the data.
