<span>Jakarta, as a megapolitan city, is always crowded with thousands of vehicles every day which results in decreased air quality due to combustion emissions and may have significant impact on human health. Particulate matter (PM<sub>2.5</sub>) pollutant that has an aerodynamic diameter fewer than 2.5 micrometers very easy enter the respiratory system so it can affect In dry...

Dust storms are one of the most frequent meteorological disasters in China, endangering agricultural production, transportation, air quality, and safety people’s lives property. Against backdrop climate change, Mongolia’s contribution to China’s dust cannot be ignored recent years. In this study, we used Weather Research Forecasting model coupled with Chemistry (WRF-Chem), along dynamic sources...

Abstract. In this paper, we rectify inconsistencies that emerge in the Weather Research and Forecasting model with chemistry (WRF-Chem) v3.2 code when using Goddard Chemistry Aerosol Radiation Transport (GOCART) aerosol module. These have been reported, corrections implemented WRF-Chem v4.1.3. Here, use a experimental setup configured over Middle East (ME) to estimate effects of these inconsist...

Nitrogen oxides (NOx) are air pollutants critical to ozone and fine particle production in the troposphere. Here, we present fuel-based emission inventories updated 2018, including for mobile source engines using Fuel-based Inventory of Vehicle Emissions (FIVEs) oil gas Oil Gas (FOG) inventory. The FIVE emissions now consistent with NEI17 estimates differing within 2% across contiguous US (CONU...

Abstract. We collected surface snow samples from three different glaciers – Yala, Thana, and Sachin in the central western Himalayas to understand spatial variability radiative impacts of light-absorbing particles. The Yala Thana Nepal Bhutan, respectively, were selected represent Himalayas. glacier Pakistan was during pre- post-monsoon seasons year 2016. analyzed for black carbon (BC) water-in...

This work presents a simulation of the plume trajectory emitted by flaring activities of the Miguel Hidalgo Refinery in Mexico. The flame of a representative sour gas flare is modeled with a CFD combustion code in order to estimate emission rates of combustion by-products of interest for air quality: acetylene, ethylene, nitrogen oxides, carbon monoxide, soot and sulfur dioxide. The emission ra...

A three-dimensional variational data assimilation (3-DVAR) algorithm for aerosols in a WRF/Chem model is presented. The WRF/Chem model uses the MOSAIC (Model for Simulating Aerosol Interactions and Chemistry) scheme, which explicitly treats eight major species (elemental/black carbon, organic carbon, nitrate, sulfate, chloride, ammonium, sodium and the sum of other inorganic, inert mineral and ...

OBJECTIVES This study sought to investigate the relationship between tubular damage and worsening renal function (WRF) in chronic heart failure (HF) BACKGROUND: WRF is associated with poor outcome in chronic HF. It is unclear whether urinary tubular markers may identify patients at risk for WRF. METHODS In 2,011 patients with chronic HF, we evaluated the ability of urinary tubular markers (N-...
