A method is described for determining wind vectors in the lower atmosphere from terrestrial stereophotography. The photographs were taken with specially adapted aerial cameras using the normal or parallel averted case with horizontal camera axes. The most favourable photographic registration was obtained on ORWO UT 16 colour reversal film. Photograph co‐ordinates and horizontal parallaxes were measured and recorded on punched tape with the Zeiss (Jena) stecometer. Vector components, which were calculated from co‐ordinate differences, and a statistical analysis were obtained by using an electronic computer.
