Title: MERTIS – The MERcury Thermal infrared Imaging Spectrometer for the Bepi-Colombo mission
Abstract: MERTIS is an imaging spectrometer for the thermal infrared wavelengths range. It covers the range from 7-14 μm at a high spectral resolution of up to 90nm which can be adapted depending on the actual surface properties to optimize the S/N ratio. MERTIS will globally map the planet with a spatial resolution of 500m and a S/N of at least 100. For a typical dayside observation the S/N ratio can exceed 1000 even for a fine grained and partly glassy surface. MERTIS will map 5-10% of the surface with a spatial resolution higher than 500m. The flexibility of the instrumental setup will allow to study the composition of the radar bright polar deposits with a S/N ratio of >50 for an assumed surface temperature of 200K.
