AIM-North is an innovative satellite mission concept that is under consideration by the Canadian Space Agency (CSA). AIM-North would provide observations of unprecedented frequency, density and quality for monitoring greenhouse gases (GHGs), air quality (AQ) and solar induced fluorescence (SIF) from vegetation in northern regions. AIM-North would use a constellation of two satellites in a highly elliptical orbit (HEO) configuration, enabling observations over land from about 40-80°N, multiple times per day. Enhancing the mission with additional spectral bands could provide complementary observations for weather, climate and AQ research and operations. The project is a collaborative effort between Environment and Climate Change Canada (ECCC), other federal and provincial government departments, Canadian academia, Canadian industry and international scientists.
