Sudden Infant Death Syndrome (SIDS), according to a definition on the Mayo Clinic website, is the unexplained death, usually during sleep, of a seemingly healthy baby less than a year old.. The cause is still unknown, but it does not appear to be suffocation, according to the SIDS Network.
Albedo (/Ã¦lËbiËdoÊ/) is a measure for reflectance or optical brightness (Latin albedo, whiteness). It is dimensionless and measured on a scale from zero (corresponding to a black body that absorbs all incident radiation) to one (corresponding to a white body that reflects all incident radiation).
These maps show albedo on a scale from 0 (no incoming sunlight being reflected) to 0.9 (nearly all incoming light being reflected). Darker blue colors indicate that the surface is not reflecting much light, while paler blues indicate higher proportions of incoming light are being reflected.
