Title:WORK OF THE METEOROLOGICAL OFFICE [Main Title]
Film Number:IWM 355
Summary: The Meteorological Section, Royal Engineers, near Montreuil, Western Front, 16th October 1918.
Description: Three members of the section, all from different regiments, use gas cylinders from a portable trailer to inflate two small weather balloons, using a lead weight to determine the gas pressure of each balloon. One soldier uses a ranging instrument to track a balloon as another releases it. The third opens a standard weather-station box and takes readings from the hygrometer and the rain gauge. He fits the wind gauge and takes a reading from that also.
