 ALM North is a proposed satellite mission that would provide unprecedented frequency and density observations for monitoring northern greenhouse gases, equality and vegetation using two satellites in a highly elliptical orbit formation, carrying the infrared to shortwave infrared imaging spectrometers and an ultraviolet visible imaging spectrometer. The resulting data would improve our ability to forecast northern air quality and quantify fluxes of GHG and AQ species from forests, permafrost, biomass burning and anthropogenic activity, furthering our scientific understanding of these processes and supporting environmental policy.
