1. A method of measuring an atmospheric wind condition via a LIDAR system, comprising:

  • generating a common beam of substantially monochromatic light;

    receiving at least first and second portions of scattered light from a first portion of an atmosphere, wherein the first and second portions of scattered light are generated in response to the common beam, the first and second portions of scattered light are received at corresponding first and second locations that are relatively remote with respect to one another, at least one of the first and second locations is relatively remote with respect to a source of the common beam of substantially monochromatic light, and the first and second portions of scattered light are received along corresponding first and second directions that are linearly independent with respect to one another;

    determining a first component of a velocity of the first portion of the atmosphere in the first direction from the first portion of scattered light in response to a first Doppler shift of a frequency of the first portion of scattered light;

    determining a second component of the velocity of the first portion of the atmosphere in the second direction from the second portion of scattered light in response to a second Doppler shift of a frequency of the second portion of scattered light; and

    determining at least one of a magnitude and a direction of the velocity in response to at least the first and second components of velocity and the first and second directions.
