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).
In relation to the climate, this is an important variable because it expresses the proportion of solar radiation reflected into space by the Earth's surface and atmosphere, which therefore does not heat the planet. Albedo is a dimensionless quantity.
