Abstract. This paper describes the technical specifications of the extensions made to the middle atmospheric lidar facility at the Leibniz Institute of Atmospheric Physics in Kühlungsborn, Germany (54.12° N, 11.77° E). The upgrade complements the existing, vertically pointing daylight-capable Rayleigh-Mie-Raman (RMR) temperature lidar with a 2-beam, nighttime-only RMR wind-temperature lidar. The 2-beam system comprises an independent lidar with laser, telescopes, and detectors, which is synchronized with and adapted to the temperature lidar. This work intends to highlight the recent innovations in the construction of a 3-beam Doppler-Rayleigh wind lidar system using the single-edge Iodine-cell technique, which allows for the simultaneous measurement of wind, temperature, and aerosols. We will detail supporting subsystems that allow for a high degree of lidar automation and concisely provide key technical information about the system that will support readers in the development of additional Doppler-Rayleigh wind lidar systems. We show an example of time-resolved temperature and wind soundings reaching up to ~90 km. These data agree well with ECMWF-IFS profiles between 35 and ~50 km but show a much larger variability above. In the companion article, we will present the algorithm design and uncertainty budgets associated with the data processing chain.

Short summary
This paper describes a new lidar system developed in Germany intended to study wind and temperature at night in the middle atmosphere. The paper explains how we have set up the system to work automatically and gives technical details for anyone who wants to build a similar system. We present a case study showing temperatures and winds at different altitudes. In a future article, we will present how we process the data and deal with uncertainties.
