Excerpt from Instructions for Making Pilot Balloon Observations Observations with pilot balloons are made for the purpose Of determining wind direction and velocity at various altitudes; also height, direction, and velocity Of clouds Whenever the balloons enter their bases. The apparatus and methods used are described in detail in the following sections. Briefly, the Observations are made by following with a theodolite the flight Of small rubber balloons filled With hydrogen or helium gas. The angles Of azimuth and elevation are Observed and recorded, and these data, together with the balloon's altitude at successive intervals Of time, make possible the construction Of a horizontal projection Of the path followed and the determination from this projection of Wind direction and velocity at various levels.
