A line connecting points of equal ozone concentrations.

Lines on a graph connecting points of constant value; e.g., isopleths of visibility are lines of equal visibility.

A broad term for any line on a weather map connecting points with equal values of a particular atmospheric variable (temperature, dew point, etc.). Isotherms, isotachs, etc. are all examples of isopleths.

A line of constant or uniform value of a given quantity. See isanostere, isobar, isohaline, isopycnic, and isotherm.

a line drawn on a map connecting points having the same numerical value of some variable

a line joigning geographical locations in which the pasture has an active period of the same length, the active period being the length of time during which the herbaceous cover reaches the end of its vegetative cycle and provides forage

a line or curve of equal values

a line symbol connecting points of equal value

A line of equal value of given quantity.

Line of constant value for a variable on a chart or map. Ozone concentrations are usually isoplethed every 25 Dobson units.

a general term for a line connecting points of equal value of some quantity. Isobars, isotherms, etc. are all examples of isopleths.

A line on a map connecting points at which a given variable has a specified constant value.

The line or area represented by an isoconcentration.

Line that connects points of equal amounts of a quantity such as evapotranspiration, chloride concentration, etc.

A line connecting equal points of value. Also called an isoline.
