Tropospheric ozone spectrum, the most common way to measure ozone is to measure how much of this light spectrum is absorbed in the atmosphere. Because the stratosphere has higher ozone concentration than the troposphere, it is important for remote sensing instruments to be able to determine altitude along with the concentration measurements. The TOMS-EP instrument aboard a satellite from NASA is an example of an ozone layer measuring satellite , and TES is an example of an ozone measuring satellite that is specifically for the troposphere. Lidar is a common ground based remote sensing technique to measure ozone. TOLnet is the network
Layer by Layer Layer by Layer The Layer by Layer method is a method of solving the 3x3x3 Rubik's Cube. Many beginners' methods use this approach, but it also forms the basis of the CFOP speedcubing technique. The Layer by Layer Method was pioneered by David Singmaster in his 1980 book "Notes on Rubik's "Magic Cube"". The same idea was adopted by James G. Nourse in his "The Simple Solution to Rubik's Cube" which became the bestselling book of 1981, and similar approaches could be found in Don Taylor's "Mastering Rubik's Cube" and Cyril Östrop's "Solving the Cube" from the same era.
