Abstract

Intensity measurements characterizing at least two absorption lines for a molecule of interest within at least one sample of gas may be used to calculate at least one ratio which may be associated with a level of an environmental parameter of interest (e.g. temperature). Related apparatuses, techniques, systems, computer program products are also described. The intensity measurements take place from an exterior surface of a mobile platform (e. g. an aircraft).
