Abstract In 2019, an unusually strong positive Indian Ocean Dipole spawned hot and dry weather in southeastern Australia, which promoted devastating wildfires the period from September 2019 to February 2020. The fires produced large plumes of biomass burning aerosols that prevented sunlight reaching Earth’s surface, this way elicited regional radiative cooling. We estimated direct aerosol forcing (ARF) resulting these wildfires, based on Moderate Resolution Imaging Spectroradiometer...
The effects of increased dimethyl-sulfide (DMS) emissions due to marine phytoplankton activity are examined using an atmosphere-ocean coupled climate model. As the DMS emission flux from ocean increases globally, large-scale cooling occurs DMS-cloud condensation nuclei (CCN)-cloud albedo interactions. This as further increased, with most pronounced effect occurring over Arctic, which is likely associated a change in sea-ice fraction sea ice mediates air-sea exchange radiation, moisture and...
The worst forest fires in Korean history broke out on March 4, 2022 and lasted for ten days. In order to monitor the catastrophic fires, Geostationary Korea Multi-Purpose Satellite (GK)-2 A Advanced Meteorological Imager (AMI) GK-2B Environment Monitoring Spectrometer (GEMS) data were used this study. Aerosol optical depth (AOD) irretrievable biomass-burning aerosols produced with water vapor classified as could-contaminated, was reconstructed by ultraviolet aerosol index (UVAI). Afterward,...
The intense Siberian wildfires in the summer of 2019 had devastating effects. Here dynamics these is described taking into consideration legal act that determines modern forest management Russia – Forest Code-2006. This changed approach to wildfire by introducing control zones, where authorities can legally ignore due their inaccessibility or remoteness from firefighting infrastructure. Remote sensing and open reports show most (60–98%, depending on day) Siberia were zones. Notably, largest...
Abstract. A new sulfate aerosol hygroscopicity parameter (κSO4) parameterization is suggested that capable of considering the two major aerosols, H2SO4 and (NH4)2SO4, using molar ratio ammonium to (R). An alternative κSO4 method also utilizes typical geographical distribution patterns ammonium, which can be used when data are not available for model calculation. Using Weather Research Forecasting coupled with Chemistry (WRF-Chem), impacts different parameterizations on cloud microphysical...
Sewer systems, which consist of wastewater treatment plants (WWTPs) and sewer networks, are important urban water infrastructure that helps to improve quality prevent flooding. While they recognized as a major source methane emissions with considerable potential, accurate quantification from sewage systems has not yet been achieved. Here, we measured atmospheric the network using mobile laboratory, consists electric vehicle monitoring instruments for Greenhouse Gas (GHG) such carbon dioxide...
In March 2022, an unprecedented largest forest fire occurred in South Korea, burning 22,477 ha of for two weeks. this study, we studied the causes these fires based on analysis all meteorological data available over 100 years and also investigated their effects air quality obtained from ground-based observations (AirKorea Asian Initiative Clean Air Networks (AICAN)) satellite data. Analysis results reveal changes climate regime cold wet winter conditions to hot dry conditions. The...
Airborne aerosols can alter incoming solar radiation inducing different radiative responses, yet the potential ecological effects of changes in degree linear polarization (DoLP) by light alteration remain largely unknown. Light is an important navigational cue for honeybee which a threshold intensity (i.e., DoLP) reliable response known as 15%. Here, we quantify relationship between mass concentration airborne fine particulate matter (PM2.5) and DoLP ground-based observation to provide...
