radiation reflectivity
1Reflectivity — In photometry and heat transfer, reflectivity is the fraction of incident radiation reflected by a surface. In full generality it must be treated as a directional property that is a function of the reflected direction, the incident direction, and …
2Cloud reflectivity modification — Cloud reflectivity enhancement is also known as marine cloud brightening or cloud whitening on low cloud. An opposite scheme exists to reduce the reflectivity of higher, colder cirrus clouds.[1] It is a geoengineering technique that works by… …
3Solar radiation pressure — In astronomy, Solar radiation pressure is the force exerted by solar radiation on objects within its reach. Solar radiation pressure is of interest in astrodynamics, as it is one source of the orbital perturbations.The disturbance force can be… …
4Stanford Synchrotron Radiation Laboratory — The Stanford Synchrotron Radiation Laboratory, a division of Stanford Linear Accelerator Center, is operated by Stanford University for the Department of Energy. SSRL is a National User Facility which provides synchrotron radiation, a name given… …
5climate — /kluy mit/, n. 1. the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years. 2. a region or… …
6Weather radar — in Norman, Oklahoma with rainshaft …
7Albedo — The albedo of an object is the extent to which it diffusely reflects light from the sun. It is therefore a more specific form of the term reflectivity. Albedo is defined asthe ratio of diffusely reflected to incident electromagnetic radiation. It …
8Cool roof — In the world of industrial and commercial buildings, a cool roof is a roofing system that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the… …
9Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change …
10coal — coalless, adj. /kohl/, n. 1. a black or dark brown combustible mineral substance consisting of carbonized vegetable matter, used as a fuel. Cf. anthracite, bituminous coal, lignite. 2. a piece of glowing, charred, or burned wood or other… …
