Apply correction factor for small particle data measurements #40

Closed anushadatar closed 3 years ago

anushadatar commented 3 years ago

Side-by-side deployments of other particle measurement instruments next to those in the network and determined there is a correction factor for PM1, P2.5, and PM10 data, and its 17x. There’s a consistent and systematic undercounting issue with the optical measurement (as opposed to a mass-based measurement). We need to increase these values by that factor in the backend.

By PM1, is that the bin0 0.3-0.5 measurement?

anushadatar commented 3 years ago

I think it distinctly does not include the 0.3-0..5 measurement, because I feel like I asked that in class (notes are here) might be worth asking to clarify though

Inkering commented 3 years ago

hmm ok, I don't think we even show a distinct PM1 category 🧐

Applied the factors. Even with the corrections the readings are below WHO baselines as we somewhat expected
