SRML Glossary — "O" Special thanks to NREL We'd like to thank the National Renewable Energy Laboratory for making available to us their glossary, which is the basis of ours. We've edited and reformatted it, and linked it to our Web pages, and we'll continue to add our own specialized terms, illustrations, and examples. Please note that the Solar Radiation Monitoring Laboratory takes full responsibility for any inaccuracies that may occur.

| (Technically
known as the relative aerosol optical depth) Usually considered to
be synonymous with the airmass, is the approximate
number of aerosols in a path through the atmosphere relative to the standard
number of aerosols in a vertical path through a clean, dry atmosphere at
sea level.

| The direction
that a solar energy collector faces. The
two components of orientation are the tilt angle (the angle the collector
makes from the horizontal) and the aspect angle (the angle the collector
makes from North).

| The layer
in the atmosphere with the most ozone, usually at an altitude of 25 km.
Ozone is created from oxygen by ultraviolet
radiation bombardment. Because ozone tends to absorb and block ultraviolet
radiation, a substantial ozone layer reduces the risk of skin cancer.
