| Zusammenfassung |
| Terrestrial albedo is an important factor in the radiative budget of the
Earth's climate system. Albedo can be measured from satellites, but so far
only terrestrial earthshine observations offer an alternative. Methods
are based on observing the earthshine to moonshine ratio on the Moon,
followed by analysis and modelling. We have designed, built and installed
a new earthshine observing system at the NOAA Mauna Loa Observatory
on Hawaii, and in this poster we present observations from the startup
phase of operations. A comparison is made between data-reduction methods
which yield earthshine intensity relative to moonshine intensity, or,
directly, estimates of terrestrial albedo. |
