A comparison of ground-based Doppler lidar and airborne in situ wind observations above complex terrain

Airborne wind observations collected by the National Oceanic and Atmospheric Administration’s (NOAA) WP-3D aircraft are compared with the winds retrieved by the NOAA/Environmental Technology Laboratory’s ground-based scanning Doppler lidar within the Wipp Valley during the Special Observing Period of the Mesoscale Alpine Programme. Comparisons are performed along individual  ight tracks and ov...

Airborne Lidar Observations of Water Vapour Variability and Transport

Water vapour, a minor constituent of the earth’s atmosphere, plays a major role in the radiation budget and the water cycle with important implications for weather and climate. Due to the heterogeneous distribution of its sources, evaporation, and sinks, condensation and precipitation, and due to the complexity of atmospheric motion and mixing, its distribution is highly variable. Despite the r...

Doppler lidar observations of Russian forest fire plumes over Helsinki

In August 2006, forest fires in north-western Russia led to elevated concentrations of fine particles reducing air quality in southern Finland over a number of weeks. Predominately easterly and south-easterly winds resulted in smoke plumes extending over the Gulf of Finland and affecting eastern and southern Finland during 7–14 August 2006 and 21–23 August 2006. This article describes observati...
