The Scout CubeMAP mission is a constellation of CubeSats that focus on understanding and quantifying atmospheric processes in the upper troposphere and in the stratosphere. In particular, it will make observations in tropical and sub-tropical latitudes to observe gases such as water vapour, carbon dioxide, methane, ozone and nitrous oxide as well as aerosols – all of which play a key role in the greenhouse effect and climate change. The mission comprises three CubeSats, each carrying thermal infrared spectrometer, as well as a visible near-infrared hyperspectral solar disk imager as a secondary instrument. CubeMAP is one of the new Scout missions, which are a new element in ESA's Earth Observation Programme. Embracing the concept of New Space, the idea is to prove new concepts using small satellites that add scientific value to data from current satellites.
CubeMAP was formally called EPS-MACCS.
