The rate of increase or decrease of a variable magnitude, or the curve which represents it; as, a thermometric gradient.
The variation of the concentration of a chemical substance in solution through some linear path; also called concentration gradient; -- usually measured in concentration units per unit distance. Concentration gradients are created naturally, e.g. by the diffusion of a substance from a point of high concentration toward regions of lower concentration within a body of liquid; in laboratory techniques they may be made artificially.
An expression of slope or an angle of slope. Gradient may be expressed as a fraction or percentage, for example, 1/50 (1 in 50) metres indicates that the elevation changes (rises or falls) by one metre in a horizontal distance of 50 metres (or a 2% grade).

Informally this connotes the changing of some property over space or time, e.g. there is a gradient in the density of the atmosphere as one proceeds vertically upward or a gradient in SST as one travels from the equator to the poles. Formally, the gradient is the result of a gradient operator operating on some scalar quantity. The gradient of some scalar quantity can be mathematically expressed as where is the gradient operator and ,, and the component unit vectors and differential operators in a Cartesian coordinate system. See Dutton (1986).

As you move away from the road, the amount of lead in the surface soil decreases. This change in the lead concentration with distance from the road is called a gradient.

The gradient is the rate of change (i.e. magnitude of first derivative) at a point. Here it specifically refers to the rate at which the brightness temperatures change with respect to distance.

For the gridded data it's the same except the adjacent column and row are used.

In magnetic surveys, the gradient is the change of the magnetic field over a distance, either vertically or horizontally in either of two directions. Gradient data is often measured, or calculated from the total magnetic field data because it changes more quickly over distance than the total magnetic field, and so may provide a more precise measure of the location of a source. See also analytic signal.
