Determination of the Planetary Boundary Layer Height using the Liu and Liang Method for Solar Eclipses

The planetary boundary layer (PBL) height is calculated using the Liu and Liang approach, which combines the use of meteorological data. The analysis of potential temperature, humidity, and wind speed profiles is the main technique used in this method. Finding steep points in these profiles—especially when a stable layer (temperature inversion) starts to inhibit vertical motion—is usually how one determines the PBL height. The method used by Liu and Liang improves this procedure by combining observational data from multiple sources. delivering a more precise and dynamic estimate of the PBL height under changing atmospheric circumstances by using statistical models to decrease noise. The technique is especially useful for research on climate modeling, weather forecasting, and atmospheric pollution.
