New project to measure all-important mesospheric ozone!
The Thule institute of the University of Oulu has granted a four year funding for the MeMO project. The project is led by Thomas with many CHAMOS people in the team. The idea is to measure mesospheric ozone using a low-cost ground-based instrument, based on satellite TV receivers operation at 11 GHz. The funding covers a post-doc and two PhD students for 2017-2021, and includes also building of instruments.

JAXA has successfully launched the ERG satellite to orbit! Important to CHAMOS, measurements of energetic electrons can now be made using the Plasma Particle Experiment Suite (PPE) which has 62 energy channels in the range of 10 eV to 20 MeV. Congratulations to the ISEE ERG team! More information about the ERG mission.
