Time evolution of mole fractions of organic molecules. The molecules represented by each chemical formula are as follows: hydrogen cyanide (HCN), formaldehyde (CH2O), methanol (CH3OH), formic acid (HCOOH), isocyanic acid

Phase-dependent measurements of Earth’s broadband visual apparent albedo, including historic observations from Danjon (1928). Mission or observing technique is indicated by datapoint color and shape. Uncertainties are indicated, which are
