Enrichment of the atmosphere surrounding a plant or crop, that is, the canopy of the crop, by increasing the concentration of carbon dioxide.
Industry:Weather
Energy produced or absorbed in the process of a chemical reaction. In such a reaction, energy losses or gains usually involve only the outermost electrons of the atoms or ions of the system undergoing change; here a chemical bond of some type is established or broken without disrupting the original atomic or ionic identities of the constituents. Chemical changes, according to the nature of the materials entering into the change, may be induced by heat (thermochemical), light (photochemical), and electric (electrochemical) energies.
Industry:Weather
Deviation from Stokes's law when particle size approaches the mean free path of air molecules.
Industry:Weather
Devices designed to reduce the amount of emissions from automobiles. The current (so-called three-way) systems use a heated metal catalyst to reduce the emissions of carbon monoxide (CO), hydrocarbons, and nitric oxide (NO), all of which contribute to the formation of photochemical smog.
Industry:Weather
Cyclic hydrocarbon, formula C6H12, consisting of a symmetrical six-membered ring formed from -CH2- linkages. Cyclohexane is widely used as a solvent and has been detected in ambient air samples.
Industry:Weather
Creation of a lookup table that increases a range of pixel values in an image when mapped to the display device. For example, mapping the input range of 10–20 to display a range of 100–200 is an example of contrast stretching. It is used to show fine detail in an image.
Industry:Weather
Common name for n-hexadecane, C16H34, a large alkane with good ignition quality, which is used as a diesel fuel. The cetane number of a fuel is a measure of the quality of a diesel fuel; it is defined as being the fraction of cetane in a blend of cetane and a less reactive compound that would have the same ignition quality as the fuel in question. See alkanes, octane.
Industry:Weather
Constancy with time of a given physical property during a specific process.
Industry:Weather
Cloud processes (growth, evaporation, etc. ) taking place on the scale of the individual aerosol or precipitation particle as opposed to the scale of the visual cloud. See cloud physics.
