We combined the temperature profile retrieved from the Imaging UltraViolet Spectrometer (IUVS) on Mars Atmosphere and Volatile EvolutioN (MAVEN) [1] and from the Mars Climate Sounder (MCS) on Mars Reconnaissance Orbiter (MRO) [2] to obtain a measured temperature profiles spanning the altitude range from the lower (~20 km) up to the upper (~160 km) atmosphere. A temperature profile that covers such a large altitude range will allow us to investigate coupling among atmospheric regions both for static structures controlled by radiative exchange and for propagating structures such as tides and waves. To construct the merged temperature profile we required IUVS and MCS measurements at similar locations (latitude, longitude, and local time). The latitude and local time distribution of the measurements is shown.
