Abstract. Urban areas are hot spots of intense emissions, and they influence air quality not only locally but on a regional or even global scale. The impact urban emissions over different scales depends the dilution chemical transformation plumes which governed by local- regional-scale meteorological conditions. These influenced presence urbanized land surface via so-called canopy forcing (UCMF...

Abstract. We present the WRF-GC model v2.0, an online two-way coupling of Weather Research and Forecasting (WRF) meteorological (v3.9.1.1) GEOS-Chem (v12.7.2). v2.0 is built on modular framework v1.0 further includes aerosol–radiation interaction (ARI) aerosol–cloud (ACI) based bulk aerosol mass composition, as well capability to nest multiple domains for high-resolution simulations. first impl...

Introduction Conclusions References

This study investigates the climatology and variability of summer aerosol optical depth (AOD) over Arabian Peninsula (AP) using a long-term high-resolution Weather Research Forecasting model coupled with chemistry module (WRF-Chem) simulation, available ground-based satellite observations, reanalysis products from 2008 to 2018. The simulated spatial distribution AOD agrees well observations AP,...

This work presents new climate and emissions scenarios to investigate changes on future meteorology air quality in the U.S. Here, we employ a dynamically downscaled Weather Research Forecasting model coupled with chemistry (WRF/Chem) simulations that use two Intergovernmental Panel Climate Change (i.e., A1B B2) integrated explicitly projected from novel Technology Driver Model (TDM). The 2046–2...

BACKGROUND Data comparing effects of transient worsening renal function (WRFt) and persistent WRF (WRFp) on outcomes in patients hospitalized with acute heart failure (AHF) are lacking. We determined the characteristics of hospitalized AHF patients who experienced no worsening renal function (non-WRF), WRFt, or WRFp, and the relationship between cohorts and AHF-related outcomes. METHODS AND R...

A polar-optimized version of the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) was developed to fill climate and synoptic needs of the polar science community and to achieve an improved regional performance. To continue the goal of enhanced polar mesoscale modeling, polar optimization should now be applied toward the state-of-the-a...

Abstract. We have investigated trifluoroacetic acid (TFA) formation from emissions of HFO-1234yf (CF3CFH2), its dry and wet deposition, rainwater concentration over India, China, the Middle East with GEOS-Chem WRF-Chem models. estimated TFA deposition concentrations between 2020 2040 for four previously published emission scenarios to bound possible levels TFA. evaluated capability capture proc...

OBJECTIVES To determine whether venous congestion, rather than impairment of cardiac output, is primarily associated with the development of worsening renal function (WRF) in patients with advanced decompensated heart failure (ADHF). BACKGROUND Reduced cardiac output is traditionally believed to be the main determinant of WRF in patients with ADHF. METHODS A total of 145 consecutive patient...

An increase in atmospheric pollution markedly affects the climatic environment. Aerosol is main component of pollutants and has a significant influence on changes reference crop evapotranspiration (ET0), while effects aerosol ET0 are still unclear. In this study, meteorological elements Henan Province was evaluated using online two-way coupling WRF (Weather Research Forecast)–Chem. The results ...
