Sable Island has been the subject of extensive scientific research over the years. The Meteorological Service of Canada operated a wide range of manual and automated instruments, including the Automated Weather Observing System, an aerology program measuring conditions in the upper atmosphere using a radiosonde carried aloft by a hydrogen-filled weather balloon to altitudes beyond , and a program collecting data on background levels of carbon dioxide, which began there in 1974. Research was done to monitor the long-range transport of pollution aerosols. Fog chemistry has also been studied, examining the transport and composition of atmospheric toxins it carries. Tropospheric ozone was measured and analyzed by researchers in Canada and the United States along with 20 other North American sites. The upper-air aerology program ended on August 20, 2019.
