Abstract. The distribution of meteorological elements has always been an important factor in determining the horizontal and vertical particles atmosphere. To study effect on three-dimensional structure particles, mobile vehicle lidar fixed-location observations were collected western Guangdong–Hong Kong–Macao Greater Bay Area China during September October 2019 2020. Vertical aerosol extinction...

In the present work, we investigate possibility that long-range airborne transport of infectious aerosols could initiate an epidemic outbreak at distances downwind beyond one hundred kilometers. For this, have developed a simple atmospheric box model, which, for hypothetical case COVID-19 outbreak, was compared to more sophisticated three-dimensional transport-dispersion model (HYSPLIT) calcula...

Atmospheric pollution can affect human production life and physical mental health to a great extent. In this paper, the hourly pollutant monitoring data from five state-controlled automatic atmospheric stations in Daqing City 2017 2021 are collected analyze temporal spatial variation patterns of CO, SO 2 , NO PM 2.5 10 O 3 . And assess risks particulate matter. The HYSPLIT model is applied air ...

Dust particles have dangerous impacts on human health, the environment, and the economy. Recently dust storms, originating from Arabian countries, have increased remarkably, affecting western and central parts of Iran.HYSPLIT model and the mean monthly maps of AAI (Absorbing Aerosol Index), surface skin temperature, and top soil layer moisture from OMI (Ozone Measurement Instrument) have been u...

Vertical profiles of aerosol extinction obtained with the CALIOP lidar onboard CALIPSO are used in conjunction with the GEOS-Chem chemical transport model and NOAA’s HYSPLIT trajectory model to document three aerosol export events from East Asia to the Arctic in the year 2007. During each of these events CALIOP sampled the pollution plumes multiple times over periods of five to seven days. Midl...

BACKGROUND Bluetongue (BT) is a vector-borne disease of ruminants that has expanded its traditional global distribution in the last decade. Recently, BTV-1 emerged in Southern Spain and caused several outbreaks in livestock reaching the north of the country. The aim of this paper was to review the emergence of BTV-1 in the Basque Country (Northern Spain) during 2007 and 2008 analyzing the possi...

Even though anthropogenic mercury (Hg) emissions to the atmosphere are ∼2.5 times higher in Northern Hemisphere (NH) than Southern (SH), atmospheric Hg concentrations NH only ∼1.5 SH. Global models attribute this apparent discrepancy large SH oceanic or interhemispheric exchange of through atmosphere. However, no observational data set exists serve as a benchmark validate whether these coarse-r...

Olea pollen concentrations have been studied in relation to the typology of air masses, grain sources and marine nature during advections a coastal enclave south-eastern Iberian Peninsula. Since Spain is world's leading olive producer, growing extends throughout Mediterranean basin, this location ideal for study long-distance transport events (LTD) main season (MPS). The masses were classified ...

Abstract. To better understand the aerosol properties over Arctic, Antarctic and Tibetan Plateau (TP), optical were investigated using 13 years of CALIPSO (Cloud–Aerosol Lidar Infrared Pathfinder Satellite Observations) L3 data, back trajectories for air masses also simulated Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model. The results show that depth (AOD) has obvious s...
