Photochemical air quality models play a central role in both schentific investigation of how
pollutants evlove in the atmosphere as well as developing policies to manage air quality. In …

In order to use an air quality modeling system with confidence, model performance must be
evaluated against observations. While ozone modeling and evaluation is fairly developed …

Correlations are presented between model predictions for O3‐NOx‐hydrocarbon sensitivity
and afternoon concentrations of four “indicator species”: NOy, O3/(NOy‐NOx), HCHO/NOy …

Unbiased symmetric metrics to quantify the relative bias and error between modeled and
observed concentrations, based on the factor between measured and observed …

This article reports on the first implementation of a real-time Eulerian photochemical model
fo recast system in the United States. The forecast system consists of a tripartite set of one …

A new photochemical oxidant model, CALGRID, has been developed for regulatory
assessments of ozone control strategies. The model features: low numerical diffusion …

Guidance for the performance evaluation of three-dimensional air quality modeling systems
for particulate matter and visibility is presented. Four levels are considered: operational …

In this paper, the concept of scale analysis is applied to evaluate ozone predictions from two
regional-scale air quality models. To this end, seasonal time series of observations and …

Tropospheric ozone (O3) is considered one of the most important air pollutants affecting
human health. The role of peri-urban vegetation in modifying O3 concentrations has been …

The complex configuration of the northeastern Iberian Peninsula (NEIP) provokes a complex
behavior of photochemical pollutants, which demands a high spatial resolution when …
