The 1987 Montreal Protocol on Substances that Deplete the Ozone Layer was negotiated and signed by Canada along with 23 other countries. Since then the World Meteorological Organization has had an ongoing mandate to monitor and assess its effectiveness. To do this, they rely on high fidelity data records such as those produced by Canadian satellite instruments. This project will combine satellite and ground based measurements with Canada's OSIRIS instrument time series to produce Canada's long term data record. Canadian model results will be used to better understand this time series.
