Observation and Modelling of Boundary Layer Depth in a Region with Complex Terrain and Coastline
The purpose of this paper is to test the ability of two quite different models to simulate the combined spatial and temporal variability of Thermal Internal Boundary Layer (TIBL) depth and Mixed Layer Depth (MLD) in the complex terrain and coastline of the Lower Fraser Valley (LFV) of British Columbia, Canada during the course of one day. The models (the simple applied model of Gryning and Batchvarova (1996), and the Colorado State University Regional Atmospheric Modelling System (CSU-RAMS) described by Pielke et al. (1992)). will be tested by comparison with data gathered during a field study (called Pacific ‘93) of photochemical pollution in the LFV. The data utilized here are drawn from tethered balloon flights, free flying balloon ascents, and downlooking lidar operated from an aircraft flown at roughly 3500m ASL.
