A method of measuring an atmospheric wind condition, comprising: a. receiving at least first, second and third portions of scattered light from a first portion of an atmosphere within a first period of time, wherein said first, second and third portions of scattered light are generated along a common beam of substantially monochromatic light, said first, second and third portions of scattered light are received at corresponding first, second and third locations by different LIDAR systems (24.1, 24.2, 24.3, 24.4, 24.5) that form a network and are remote with respect to one another, at least one of said first, second and third locations is remote with respect to a source of said common beam of substantially monochromatic light, said first, second and third portions of scattered light are received along corresponding first, second and third directions, and said first, second and third directions are linearly independent with respect to one another; b. determining a first component of a wind velocity of said first portion of said atmosphere in said first direction from said first portion of scattered light responsive to a first Doppler shift of a frequency of said first portion of scattered light; c. determining a second component of said wind velocity of said first portion of said atmosphere in said second direction from said second portion of scattered light responsive to a second Doppler shift of a frequency of said second portion of scattered light; d. determining a third component of said wind velocity of said first portion of said atmosphere in said third direction from said third portion of scattered light responsive to a third Doppler shift of a frequency of said third portion of scattered light; wherein either a magnitude and direction of said wind velocity, or a measure responsive thereto or representative thereof, responsive to at least said first, second and third components of wind velocity and said first, second and third directions is determined; further comprising e. processing at least one of said first, second and third portions of scattered light with at least one interferometer so as to generate at least one fringe from said scattered light for at least one of said first, second and third portions of scattered light; f. determining at least one measure of density of said first portion of said atmosphere from at least one fringe associated with said first portion of scattered light, at least one fringe associated with said second portion of scattered light, and at least one fringe associated with said third portion of scattered light g. generating from the components of the wind velocity, wind direction and the density of the atmosphere the wind power flux density vector over a geographic area. a. receiving at least first, second and third portions of scattered light from a first portion of an atmosphere within a first period of time, wherein said first, second and third portions of scattered light are generated along a common beam of substantially monochromatic light, said first, second and third portions of scattered light are received at corresponding first, second and third locations by different LIDAR systems (24.1, 24.2, 24.3, 24.4, 24.5) that form a network and are remote with respect to one another, at least one of said first, second and third locations is remote with respect to a source of said common beam of substantially monochromatic light, said first, second and third portions of scattered light are received along corresponding first, second and third directions, and said first, second and third directions are linearly independent with respect to one another;
