SAC Seminar - Philip Judge: GeoSpheres - new ideas about solar irradiance
Oplysninger om arrangementet
Torsdag 17. september 2015, kl. 15:15 - 16:00
An inert sphere of a few metres diameter, placed in a special stable geosynchronous orbit in perpetuo, can be used for a variety of scientific experiments. Ground-based observations of such a sphere, `GeoSphere', can resolve very difficult problems in measuring the long-term solar irradiance. GeoSphere measurements will also help us understand the evolution of Earth's albedo and climate over at least the next century.
