Urbanized mountain valleys are usually prone to episodes of high concentrations air pollutants due the strong interplay between meteorology and synoptic weather conditions. The valley Chiang Mai is engulfed by with particulate matter (PM) concentration remaining above 50 µg m-3 (PM2.5, 24-hour average) during approximately 13 % days every year (mostly February April). This study presents first time continuous measurements mini- micro pulse LiDAR (MiniMPL) installed on floor Mai, providing...
Effects of electronic nonlocality in density functional theory study structural and energetic properties a pseudocubic CH3NH3PbI3 are investigated by considering coherent rotation around C-N axis CH3NH3 cation. A number truly non-local semi-local exchange correlation functionals examined comparing calculated parameters with experimental results. The vdW-DF-cx which takes into account the van der Waals consistent shows best overall performance for this system. Remarkable distinctions between...
A microscopic viewpoint of structure and dipolar configurations in hybrid organic-inorganic perovskites is crucial to understanding their stability phase transitions. The necessity incorporating dispersion interactions the state-of-the-art density functional theory for [Formula: see text] perovskite (MAPI) demonstrated this work. Some vdW methods were selected evaluate corresponding energetics properties cubic MAPI with various azimuthally rotated MA organic cation orientations. highest...
Understanding the link between emissions, atmospheric chemistry and Earth’s radiative budget remains a challenge in climate research. Such linkage arises from fact some aerosols are produced chemically atmosphere. Unlike well-mixed greenhouse gases, anthropogenic heterogeneously distributed because of localised emissions short residence time. Over historical period near-term forcers (NTCFs) including aerosol precursors, O3 precursors CH4 have broadly increased. We ask how changes...
Understanding the link between anthropogenic emissions and radiative forcing remains a grand challenge in field of climate research. Linkages arise emissions, atmospheric chemistry through formation secondary aerosols such as sulfate, nitrate organic aerosols. Sulfur dioxide (SO2) is an important aerosol precursor with largest sources coming from activity. Unlike well-mixed greenhouse gases, are heterogeneously distributed because localised short residence time. Thus SO2 conversion to...
