Century-Long Monitoring of Solar Irradiance and Earth’s Albedo Using a Stable Scattering Target in Space
  Astronomy and astrophysics

Friday 15 January 2016
from 10:30 to 11:30
at 122:026 (Nordita seminar room)
Speaker : Philip Judge (High Altitude Observatory (NCAR))
Abstract : An inert sphere of a few meters 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. I will discuss some advantages as well as disadvantages of this kind of measurement in comparison with existing measurements.
