Key Equations

$$\text{AQI} = \frac{I_{Hi} - I_{Lo}}{C_{Hi} - C_{Lo}} \times (C - C_{Lo}) + I_{Lo}$$
$$\frac{dC}{dt} = \frac{E}{V} - \frac{C}{\tau} - k_c C + \frac{C_{bg}}{\tau}$$
$$\text{NO}_2 + h\nu \xrightarrow{J_1} \text{NO} + \text{O} \quad (\lambda < 420\;\text{nm})$$
$$\text{RH} + \text{OH} \rightarrow \text{R} + \text{H}_2\text{O}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
