Keutsch Research Group Harvard University 12 Oxford Street Cambridge, MA 02138
SCoPEx is a scientific experiment to advance understanding of stratospheric aerosols that could be relevant to solar geoengineering.

Do other environmental science experiments release materials outdoors?
Yes. A number of environmental science experiments release or have released materials outdoors to create controlled perturbation for the same essential reason as we plan to do in SCoPEx—to directly control an experimental variable, which is crucial to scientific understanding. Examples of experiments include Free-Air Carbon Dioxide Enrichment (FACE) experiments, which release ozone and carbon dioxide (CO2) in the air for long durations to understand the impacts of climate and air pollution on crops and natural ecosystems; or Dispersion of Air Pollution and its Penetration into the Local Environment (DAPPLE) experiments, which have released sulfur hexafluoride (SF6) and perfluoromethylcyclohexane into urban air to study the transport of air pollutants. These experiments differ in various ways; they are listed here to merely show that there are environmental science experiments that release materials outdoors.
