Global sand and dust storms in 2008: Observation and HYSPLIT model verification

Atmospheric Environment, 2011
Abstract The HYSPLIT model has been applied to simulate the global dust distribution for 2008 using two different dust emission schemes. The first one assumes that emissions could occur from any land-use grid cell defined in the model as desert. The second emission approach uses an empirically derived algorithm based on satellite observations.

Numerical Simulation of a Severe Dust Storm over Ahvaz Using the HYSPLIT Model

International Journal of Environmental Research, 2019
In this paper, numerical simulation of a severe dust storm over Ahvaz on 16–18 June 2016 was performed using the HYSPLIT. To that end, the HYSPLIT model has been configured for different model setups to determine the most desirable suite of parameters to represent the measured concentrations better.

Forecasting air quality by integration of satellite data and hysplit trajectory model

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
This paper describes a case study of satellite data integrated with hysplit forward-trajectory model to forecast air quality in regional scale. During mid-October 2009, a severe haze event occurs in eastern China. With the help of HYSPLIT Trajectory Model, a 24-hr, 48-hr and 72-hr forward trajectory from three regions with high aerosol optical depth ...

Introduction to PySPLIT: A Python Toolkit for NOAA ARL’s HYSPLIT Model

Computing in Science and Engineering, 2018
The US National Oceanic and Atmospheric Administration Air Research Laboratorys HYSPLIT (HYbrid Single Particle Lagrangian Integrated Trajectory) model uses a hybrid Lagrangian and Eulerian calculation method to compute particle dispersion and deposition simulations as well as air parcel paths (trajectories), forward or backward in time.

Air pollutant emission characteristics and HYSPLIT model analysis during heating period in Shenyang, China

Environmental Monitoring and Assessment, 2020
To find out the characteristics and sources of atmospheric pollutants during heating period in Shenyang, the study investigated the temporal and spatial distribution of pollutants, using data of six typical atmospheric pollutants (SO2, NO2, PM10, PM2.5, O3, and CO) from November 2017 to March 2018 in 11 monitoring stations in Shenyang.

Regional Source Identification Using Lagrangian Stochastic Particle Dispersion and HYSPLIT Backward-Trajectory Models

Journal of the Air & Waste Management Association, 2011
The main objective of this study was to investigate the capabilities of the receptor-oriented inverse mode Lagrangian Stochastic Particle Dispersion Model (LSPDM) with the 12-km resolution Mesoscale Model 5 (MM5) wind field input for the assessment of source identification from seven regions impacting two receptors located in the eastern United States.

HYSPLIT Model Estimates of Atmospheric Deposition of Toxic Contaminants to the Great Lakes (An Overview)

2002
In 1987, through the addition of an Annex dedicated to Airborne Toxic Substances (Annex 15) to the Great Lakes Water Quality Agreement of 1972, the governments of the United States and Canada recognized atmospheric deposition as a significant pathway of persistent toxic substances to the Great Lakes, some of the largest bodies of fresh water in the ...

Methodology of ground aerosol sources determination based on AERONET and HYSPLIT models data results

23rd International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics, 2017
Based on the analysis of the backward trajectories of two models: BTA (Back Trajectory Analysis) of AERONET (Aerosol Robotic Network) and HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory model), the periods of arid aerosol drift from the Sahara and the Syrian Desert side were determined by the algorithm of spatiotemporal localization of

Source apportionment for African dust outbreaks over the Western Mediterranean using the HYSPLIT model

Atmospheric Research, 2011
A source apportionment technique has been applied to determine the geographical distribution of emissions in Northern Africa contributing to dust outbreaks that yield high PM10 levels at Spanish regional background stations. Seven dust episodes have been analyzed in this study.
