Abstract The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model is a state-of-the-science atmospheric dispersion that developed and maintained at the National Oceanic Atmospheric Administration’s (NOAA) Air Resources Laboratory (ARL). In early 2000s, HYSPLIT served as starting point for development of Stochastic Time-Inverted Transport (STILT) emphasizes backward-in-time si...

This present study suggests a method to calculate the SO2 flow rate from a source area to receptor areas on a regional scale using Ozone Monitoring Instrument (OMI) SO2 products, surface in situ SO2 data, and the hybrid single particle Lagrangian integrated trajectory (HYSPLIT) model. The method was implemented to calculate the SO2 flow rate from continental Asia to northeast Asia and the North...

Volcanic activity is observed worldwide with a variety of ground and space-based remote sensing instruments, each with advantages and drawbacks. No single system can give a comprehensive description of eruptive activity, and so, a multi-sensor approach is required. This work integrates infrared and microwave volcanic ash retrievals obtained from the geostationary Meteosat Second Generation (MSG...

A cluster algorithm was implemented to analyze the backward trajectories arriving in the Barcelona area (BCN), located at the eastern coast of the Iberian Peninsula. Five years of 4-day kinematic back trajectories, computed with version 4 of the Hybrid Single-Particle Lagrangian Integrated Trajectory model (HYSPLIT), were clustered and classified in groups of similar length and curvature. To de...

On 22 October 2002, a frontal system entered South Australia (SA), and over the next 36 hours associated strong winds raised dust over a wide region of eastern Australia, from central SA, extending eastwards and northeastwards through SA, New South Wales (NSW) and Queensland (Qld) (see Figs 1 and 2 for locations referred to in the text). Forty-six Bureau of Meteorology synoptic observing statio...

Accurate representation of fire emissions and smoke transport is crucial for current future wildfire-smoke projections. We present a flexible modeling framework sourced from the First Street Foundation Wildfire Model (FSF-WFM) to provide national map near-surface conditions exceeding threshold unhealthy concentrations particulate matter at or less than 2.5 µm, PM2.5. Smoke yield simulated fires...

In the present work WRF model is used to generate meteorological fields for the HYSPLIT dispersion model. Sensitivity and validation of the WRF model, is conducted by utilizing different combinations of physical parameterization schemes. For this purpose, eight different configurations are examined. Assessment of the predictions of the WRF model is carried out by computing the statistical param...
