Synoptic variability related to boundary layer and surface features observed during Pacific ʹ93

Datasets collected during Pacific ʹ93 enable us to construct a three-dimensional view of the atmosphere over the Fraser Valley (southwest British Columbia), and to examine relationships between conditions aloft and those in the boundary layer. Herein, vertical and horizontal profiles of the atmosphere obtained from a ground based Doppler lidar are examined in conjunction with data from an airborne downward looking lidar, meteorological soundings of temperature and wind profiles, synoptic charts and surface pressure analyses. These data sets aid understanding of the flow structure at a number of levels through the boundary layer and the spatial and temporal variability of topographically-induced flow.
