Web(1) Y WM = Weighted mass emissions of each pollutant, i.e., THC, CO, THCE, NMHC, NMHCE, CH 4, NO X, or CO 2, in grams per vehicle mile. (2) Y ct = Mass emissions as … WebOverview. This calculator allows users to derive NO 2 from NO x wherever NO x is predicted by modelling emissions from roads. The calculator can also be used to calculate the road component of NO x from roadside NO 2 diffusion tube measurements. Local authorities are advised to use the latest version of the tool for all future work that is ...
