A diagnostic intercomparison of modeled ozone dry deposition over North America and Europe using AQMEII4 regional-scale simulations Open
This study analyzes ozone (O3) dry deposition fluxes and velocities (Vd) from 12 regional-scale simulations that were performed over North America and Europe in Phase 4 of the Air Quality Model Evaluation International Initiative (AQMEII4)…

Ozone dry deposition through plant stomata: multi-model comparison with flux observations and the role of water stress as part of AQMEII4 Activity 2 Open
A substantial portion of tropospheric O3 dry deposition occurs after diffusion of O3 through plant stomata. Simulating stomatal uptake of O3 in 3D atmospheric chemistry models is important in the face of increasing drought-induced declines…

Simulation of Rainfall in Mumbai using Detailed Urban Morphology and the WRF-UACM Model Open
Mumbai, one of India's most densely populated cities and its economic hub, is critically vulnerable to the Indian monsoon. Frequent heavy rainfall events not only disrupt daily life but also cause significant economic and infrastructural d…

A New Aerosol Dry Deposition Model for Air Quality and Climate Modeling Open
Dry deposition of aerosols from the atmosphere is an important but poorly understood and inadequately modeled process in atmospheric systems for climate and air quality. Comparisons of currently used aerosol dry deposition models to a comp…

Development of the MPAS-CMAQ Coupled System (V1.0) for Multiscale Global Air Quality Modeling Open
The Community Multiscale Air Quality (CMAQ) model has been used for regulatory purposes at the US EPA and in the research community for decades. In 2012, we released the WRF-CMAQ coupled model that enables aerosol information from CMAQ to …

Black carbon-induced regime transition of boundary layer development stronglyamplifies severe haze Open
Black carbon (BC) aerosol can strongly influence planetary boundary layer (PBL) development and thus severe hazeformation, but its distinct role compared with scattering aerosols are not yet fully understood. Here, combiningnumerical simul…

Implementation of WRF-Urban Asymmetric Convective Model (UACM) for Simulating Urban Fog over Delhi, India Open
Accurate fog prediction in densely urbanized cities poses a challenge due to the complex influence of urban morphology on meteorological conditions in the urban roughness sublayer. This study implemented a coupled WRF-Urban Asymmetric Conv…

A single-point modeling approach for the intercomparison and evaluation of ozone dry deposition across chemical transport models (Activity 2 of AQMEII4) Open
A primary sink of air pollutants and their precursors is dry deposition. Dry deposition estimates differ across chemical transport models, yet an understanding of the model spread is incomplete. Here, we introduce Activity 2 of the Air Qua…

Sensitivity of northeastern US surface ozone predictions to the representation of atmospheric chemistry in the Community Regional Atmospheric Chemistry Multiphase Mechanism (CRACMMv1.0) Open
Chemical mechanisms describe how emissions of gases and particles evolve in the atmosphere and are used within chemical transport models to evaluate past, current, and future air quality. Thus, a chemical mechanism must provide robust and …
