Additionally, soot from faraway sources has darkened snow and ice, further decreasing albedo.
Kipp & Zonen Net Radiometers in use recording surface albedo at the Jornada test site, New Mexico, USA in May 1997.
Secondly the clouds, which have a high albedo, can create a negative feedback helping to cool the forest area.
The surface is covered with a darker material causing Hyperion to have a lower albedo compared to other icy moons.
The value of the geometric albedo of Mimas reported here, is definitely higher than the currently accepted value of about 0.5.
This could impact the global climate system through its effect on the carbon and water cycles and on the earth's albedo.
This increases the daytime albedo but also increases the night-time heat retentivity of the atmosphere for an additional heat gain.
Visible channels are percentage albedo and have values 0 to 100.
We address these objectives by producing albedo maps, and reflection and emission spectra, and observing stellar occultations.
