I am really enjoying my new PA unit. The conversion factors for PM are interesting to add to the data layers about etc.
It seems that VOC has been experimental a long time. South Coast AQMD has tested these. There are strong dependencies on environmental factors as well. Surely if these dependencies can be characterized and are available in the data some conversion can be done to make the readings more dependent on the VOC data alone?
It would be nice if a user could write their own equation based on the data at that station and graph that! You never know one of the many users may come up with acceptable conversion equation to be included in the main PA data layers?
