PASE Boundary and Buffer Layer Height Estimates. Version 1.0

For PASE NSF/NCAR C-130 research flights 1 through 14 all profiling data on (or near) station was averaged into 20 meter vertical bins. The variables potential temperature, turbulent kinetic energy (TKE), DMS concentration, SO2, and ozone concentration were all included in this analysis. The data from each profile was normalized by its respective mean value in the (mid-lower) boundary layer to remove any secular trends throughout the flight. The resultant averaged profiles were graphically compared to determine both the boundary layer height (zi) and the trade wind inversion height (TWI, or the top of the ‘buffer layer’).
