Albedo Research showed impacts of over 10%. More recently, the analysis was extended to the effects of spectral bias due to the specular reflectivity of 22 commonly occurring surface materials (both human-made and natural) and analyzes the albedo effects on the performance of seven photovoltaic materials covering three common photovoltaic system topologies: industrial (solar farms), commercial flat rooftops and residential pitched-roof applications. Because forests generally have a low albedo, (the majority of the ultraviolet and visible spectrum is absorbed through photosynthesis), some scientists have suggested that greater heat absorption by trees could offset some of the carbon benefits of afforestation (or
Albedo 0.39 track, "Albedo 0.39" is an atmospheric track building on waxing and waning synthesizer chords and arpeggios, while a voice, reputedly the album's engineer Keith Spencer-Allen, narrates various physical properties of the Earth, such as its mass, length of the year in various measurements, and, finally, its albedo. Mike DeGagne of Allmusic described the tracks as "mesmerizing trips of assorted rhythms that include elements of jazz and mild rock", that along with "Albedo 0.39", "the two parts of "Nucleogenesis" are among the strongest cuts that keep his cosmic theme from deviating, while the livelier "Pulstar" involves some impressive instrumental range and
