PBL Detection Comparison using 2D Operators

Many methods have been used to quantify the height and dynamics of the Planetary Boundary Layer (PBL). Most common are the 1D operator methods (e.g. The Haar function, The Ricker Wavelet, et cetera), however these methods often result in PBL heights that are not temporally smooth. In addition fine layer structure is often lost or undetectable using 1D analysis. Therefore, we propose that 2D image processing techniques be used to construct a temporally smooth PBL and enhance the detection of the fine PBL structure. A comparison of several 2D methods will be presented and the merits and demerits will be discussed and contrasted with 1D methods.
