What was the purpose of FIRMOS

In preparation of the Earth Explorer 9 FORUM mission, a new facility named FIRMOS (Far-Infrared Radiation Mobile Observation System) was been developed for field applications from both ground-based and airborne platforms to check with real measurements the sounding capability provided by FIR observations.

What was the outcome of FIRMOS

The unique spectral measurements provided by the combination of FIRMOS and E-AERI covering the relevant spectral region of the thermal emission of the atmosphere from 100 to 1800 cm-1, together with the other supporting lidars, radiosoundings, atmospheric state, and surface properties measurements, provide a complete dataset that can be used to constrain radiative properties of water vapour, cirrus ice particles, and snow/ice emissivity over almost all the infrared emission, including the under-explored FIR spectral range.
