Objectives and Applications The SCISAT satellite has been in continuous spaceflight operation since 2003. It now measures over sixty (60) atmospheric species at still one of the world’s highest vertical resolutions possible, and includes ozone, methane, and multiple CFCs. Many of these species are measured by no other instrument or satellite world-wide, making Canada the sole provider of these datasets globally. As of 2015, the objectives of the mission are to validate data used in: Environment Canada’s Air Quality Health Index, retrieve winds for forecasting, and retrieve chemical information from operational meteorological instruments. Additional objectives are to assess the quality of model predictions for: EC’s UV forecasting system, atmospheric carbon transport, and climate-chemistry process studies.
