The performance of the NIMH air quality modeling system (WRF–CMAQ) was analyzed based on comparison with surface measurements (i.e. operational model evaluation) for the whole year 2010. The tool for the evaluation was the web-based platform ENSEMBLEv5, allowing spatial and temporal analysis wit...
Comparison between observed and model-estimated PM2.5 (a), PM10 (b), NO2 (c), MDA8 (maximum daily 8 h average) O3 (d) concentrations from 2003 to 2019 under spatial cross-validation. Full size image Population-weighted concentrations and trends Figure 2 depicts the long-term averages ...
Analysis and comparison of evaluation methods Take national AQI and AQCI as pollution standards. The comparisons of the DCreWeight model with the D–S, KCre-Sun, Hybrid-Rule, and FSE models are in Fig. 4. For the clarity of the image, select four months from June 1, 2014 to March 31...
To better facilitate the comparison of these 3 cohorts in this analysis, follow-up for the 2006-2014 cohort was realigned to begin in the fourth year (2006) of that cohort’s original timeline, when most 2006-2014 cohort participants (>46%) were in the fourth grade. Final follow-up for...
Although this high of 118 pales in comparison to many other cities in Xinjiang province, as mentioned, the highs of pollution that come in certain months of the year are enough to skew its ratings enough to place it within the top 100 most polluted cities in the world, as of 2020. These...
