AB  - In the mesosphere and lower thermosphere (MLT) region, atomic oxygen and hydrogen are the most abundant reactive trace species and play crucial roles in the photochemistry and energy budget. Meanwhile, the MLT region is profoundly influenced by atmospheric dynamics, and tides and gravity waves are the key features thereof, which can be characterized by, e.g., temperature distributions and variations. A common way for the detection of these atmospheric quantities in the MLT region is by means of remote sensing of airglow emissions from ground or space. The aim of this work is to offer new insight into atmospheric parameters and distributions in the MLT region. It is focused on constituent and temperature sounding of this region, and presents the retrieval and analysis of atomic oxygen and hydrogen as well as temperature profiles from hydroxyl (OH) and oxygen atmospheric band (O$_{2}$ A-band) nightglow observations. Atomic oxygen and hydrogen abundances are obtained from satellite limb radiance measurements of nightglow emissions in the near-infrared region. Temperature profiles are inferred from the rotational structure of nightglow emission lines in a broad spectral region, including observation data from a ground-based instrument and also in-orbit validation data from a new instrument applying the Spatial Heterodyne Interferometer (SHI) technology. ...
