AB: Rayleigh lidar observations have been ongoing at Chatanika, Alaska (65oN, 147oW) since 1997. Noctilucent clouds have been detected by lidar in late summer since August 1998. These lidar observations have been made near local midnight during visible noctilucent cloud displays. We report observations in the summers of 1998, 1999, 2001, 2002 and 2003. The Student Nitric Oxide Explorer (SNOE) makes satellite observations of Polar Mesospheric Clouds over the entire globe. The SNOE observations have been made near local midday since summer 1998. We focus on the lidar and satellite observations in the western Arctic during the same seasons. We discuss the cloud observations in terms of local, regional, and long-term environmental factors (i.e. temperature, water).
