Multi-year temperature measurements of the middle atmosphere at Chatanika, Alaska (65°N, 147°W)
Abstract Over an eight-year period (1997–2005) Rayleigh lidar temperature measurements of the stratosphere and mesosphere (40–80 km) have been made at Poker Flat Research Range, Chatanika, Alaska (65°N, 147°W). The Rayleigh lidar measurements have been made between mid-August and mid-May. These meas...
