Thailand experiences severe air quality issues, predominantly due to PM2.5 pollution that surpasses WHO guidelines. The main sources are attributed energy production, industrial activities, vehicular emissions, agricultural burning, and transboundary transport of pollutants. Understanding the transformation these pollutants is necessary for addressing issues. Weather Research Forecasting Model coupled with Chemistry (WRF-Chem) provides information about meteorology, chemical reactions, trace...
Abstract. Accurate determination of the planetary boundary layer (PBL) height, mixing height (MLH), and aerosol top (ALT) is critical for air quality climate studies, especially in regions with complex dynamics like Chiang Mai, northern Thailand. This study develops a novel LiDAR-based methodology that incorporates temperature-based dynamic maximum analysis altitude (MAA) to decouple these layers, addressing limitations conventional methods such as Haar Wavelet Covariance Transform (WCT)....
Abstract In this study, an improvement in the estimation of mixing height is carried out by introducing a time-dependent maximum and minimum analysis altitude (TDMMAA) Haar wavelet covariance transform (WCT) technique applied to atmospheric light detection ranging (LiDAR) measurements generally used estimations. Results showed that standard method usually overestimates proposed algorithm more robust against clouds residual layers boundary layer occur nighttime early morning. The TDMMAA does...
