A high-power Raman lidar system has been installed at the high-altitude research station Schneefernerhaus (Garmisch-Partenkirchen, Germany) at 2675 inline-formula M1inlinescrollmathml unit normal m 0.125emnobreak normal a . normal s . normal l . 36pt10ptsvg-formulamathimgc66ba9c58375fb02029941ba18d549da amt-14-531-2021-ie00001.svg36pt10ptamt-14-531-2021-ie00001.png , at the side of an existing wide-range differential absorption lidar (DIAL). An industrial XeCl laser was modified for linearly polarized single-line operation at an average power of about 180 inline-formulaW. This high power and a 1.5 inline-formulam diameter receiver allow us to extend the operating range for water-vapour sounding to 20 inline-formulakm for a measurement time of just 1 h, at an uncertainty level of the mixing ratio of 1 to 2 inline-formulappm. This was achieved for a vertical resolution varied between just 0.2 and 0.6 inline-formulakm in the stratosphere. The lidar was successfully validated with a balloon-borne cryogenic frost-point hygrometer (CFH). In addition, temperature measurements up to altitudes of around 87 inline-formulakm were demonstrated for 1 h of signal averaging. The system has been calibrated with the DIAL, the CFH and radiosondes.
