Abstract. A lidar for middle atmospheric research is being developed at Millstone Hill / MIT Haystack Observatory (42.6N, 71.5W). The lidar obtains temperature profiles between 30 and 90 km in altitude during the night and up to 70 km during the day by using the Rayleigh lidar technique. A 1.2 m, f/200 steerable telescope is used in both the transmit and receive stages in this monostatic instrument. The long (240 m) focal length is advantageous for daytime use because of the naturally narrow field of view. The lidar will be suitable for studies of mesospheric temperature inversions and gravity waves.
