This paper describes the development and initial applications of the Model and Observation Evaluation Tool (MONET) v1.0. MONET was developed to evaluate the Community Multiscale Air Quality Model (CMAQ) for the NOAA National Air Quality Forecast Capability (NAQFC) modeling system. MONET is designed to be a modularized Python package for (1) pairing model output to observational data in space an...

Contributions of the emissions from a U.K. regulated fossil-fuel power station to regional air pollution and deposition are estimated using four air quality modeling systems for the year 2003. The modeling systems vary in complexity and emphasis in the way they treat atmospheric and chemical processes, and include the Community Multiscale Air Quality (CMAQ) modeling system in its versions 4.6 a...

Herein, we present the initial application of NOAA-EPA Atmosphere-Chemistry Coupler (NACC) in cloud (“NACC-Cloud”, version 1), which processes NOAA’s operational Global Forecast System 16 (GFSv16) meteorology on-demand and produces model-ready meteorological files needed to drive U.S. EPA’s Community Multiscale Air Quality (CMAQ) model. NACC is adapted from Meteorology-Chemistry Interface Proce...

Formation of aerosol from biogenic hydrocarbons relies heavily on anthropogenic emissions since they control the availability species such as sulfate and nitrate, through them, acidity (pH). To elucidate role that play in regulating Secondary Organic Aerosol (SOA), we utilize 2013 Southern Oxidant Study (SOAS) dataset to enhance extensive mechanism isoprene epoxydiol (IEPOX)-mediated SOA format...

18 Land in the southeastern U.S. is expected to change, e.g., given the potential demand 19 to develop forest-to-fuel technologies or, conversely, cropification of current forests to 20 increase food production. Possible future PM2.5 and O3 air quality for two land use/land cover 21 change (LULCC) scenarios, reforestation and cropland conversion, are compared to a 22 reference case scenario for...

The impact of regional emissions (e.g., domestic and international) on surface particulate matter (PM) concentrations in the Seoul metropolitan area (SMA), South Korea, and its sensitivities to meteorology and emissions inventories are quantitatively estimated for 2014 using regional air quality modeling systems. Located on the downwind side of strong sources of anthropogenic emissions, South K...

The effect of benzo(a)pyrene (BaP) ship emissions in the greater North Sea region is investigated in this study. The carcinogenic BaP which belongs to the group of polycyclic aromatic hydrocarbons (PAHs) occurs mainly particle bound at temperatures prevailing in the mid-latitudes. The BaP concentration and deposition distribution is investigated by means of the Community Multiscale Air Quality ...
