- Abstract:
- Noctilucent clouds are thin layers of ice particles that occur around 82 km during summer at high latitudes. They were first reported in 1885, and have since appeared more frequently and at lower latitudes, leading to speculation that they are an early warning of climate change. Recently rocket-borne particle detectors have revealed, against all expectations, that the particles can be positively charged, indicated very efficient photoelectric emission. This phenomenon, which impacts on VHF radar detection, is unexplained, although meteoric metals (Na and Fe) are likely to play a role. In this project we will measure the work function, the photoelectric yield and the complex refractive index for pure and metal-doped ice surfaces, for input into a new comprehensive model of noctilucent clouds.
