MARSCHALS immediately before roll-out

MARSCHALS is a millimetre-wave limb sounding spectrometer currently deployed from the Russian M-55 Geophysica high-altitude aircraft.

The instrument is designed to measure vertical profiles of ozone, water vapour, carbon monoxide, nitrous oxide, nitric acid and other gaseous components of the Earth's atmosphere.

The instrument was developed and built at RAL Space by the MMT group (link opens in a new window) (link opens in a new window)as contractors to ESA (link opens in a new window). The Remote Sensing Group (link opens in a new window) at RAL Space are responsible for defining the instrument science objectives and measurement flights, and for data analysis. The mission is also a demonstrator for a future space-borne instrument on missions such as PREMIER, proposed to ESA.
