Associations Between Meteorological and Air Pollution Variables and Dust Storm Events Controlling for Time of Year
| Association point estimate | p value | 95% CI | |
|---|---|---|---|
| O3 concentration (ppb) | −0.52 | 0.0194 | −0.95, −0.08 |
| PM2.5 concentration (μg/m3) | 3.7 | 2.0 × 10−118 | 3.4, 4.0 |
| PM10 concentration (μg/m3) | 47.8 | 0 | 46.2, 49.3 |
| Precipitation (inches) | −0.0085 | 0.071 | −0.0176, 0.0007 |
| Average temperature (°F) | 2.38 | 2.5 × 10−83 | 2.14, 2.62 |
| Dew point temperature (°F) | 2.34 | 1.3 × 10−35 | 1.97, 2.71 |
Note. Associations were estimated using mixed effects models with fixed nonlinear time‐of‐year effects and random intercept by season‐within‐year and ZIP code.
