Comment:
Is there a certain reason why you measure the PM emission in Particlemass instead of Particlenumber? As far as I know: the smaller the Particles, the more dangerous they are. And few bigger Particles cover a huge amount of small Particles if you measure in Particlemass. At the moment portable Particle Counter for diesel exhausts are developed for a new Swiss Regulation. If you take this into account, this could also offer opportunities to California to implement target-oriented regulations and field tests for less pollution and healthier air.
