.- alpha
Non-proportional fraction factor (0 <= a <= 1). Default value = 0.20 (for NO_2).
- RV
Reference value. Default value = 200 (for NO_2).
- U_RV
Standard measurement uncertainty around the RV. Default value = 0.24 (for NO_2).

Details
Compute root mean square uncertainty of time series. For parameters see Table 6 of: Fairmode MQO Guidance V3.2
$$ \mathrm{RMS}_U = U_r(RV) \sqrt{(1 - \alpha^2) (\overline{O}^2 + \sigma_O^2) + \alpha^2 RV^2} $$
