Meteorology

The level at which a parcel of moist air lifted dry-adiabatically would become saturated. On a thermodynamic diagram it is located at the point of intersection of the dry adiabat through the point ...

Lightning imaging sensor (LIS)

Weather; Meteorology

An instrument designed to detect lightning from space as part of TRMM.

Laser-induced fluorescence (LIF)

Weather; Meteorology

Experimental technique in which the absorption of laser radiation excites a molecule or atom to an excited energy level, followed by emission of radiation as the system relaxes. The technique has ...

Level of free sink (LFS)

Weather; Meteorology

The level at which a parcel of descending air becomes cooler than its surroundings. On a thermodynamic diagram the level of free sink is given by the point of intersection of the process curve ...

Lookup table (LUT)

Weather; Meteorology

A mapping of an integer value to another integer value. This is used in displaying images and represents a mapping of the pixel value in the image or picture to the value shown on the display device. ...

Limit of convection (LOC)

Weather; Meteorology

The level of neutral buoyancy for a saturated rising air parcel. If a cloudy air parcel is rising under its own buoyancy, then the parcel can rise to the altitude where the virtual potential ...

Local thermodynamic equilibrium (LTE)

Weather; Meteorology

A condition under which matter emits radiation based on its intrinsic properties and its temperature, uninfluenced by the magnitude of any incident radiation. LTE occurs when the radiant energy ...
