about the ozone units? #2

Closed maurosc3ner closed 5 months ago

maurosc3ner commented 5 months ago

I have used this package successfully, but I want to double check that ozone units returned are correct (PPM).

A division by 1000 is required to meet EPA thresholds (guidelines->https://www.airnow.gov/sites/default/files/2020-05/aqi-technical-assistance-document-sept2018.pdf).

Thanks

Hi Esteban, I think that the units are correct. We are using estimates very similar to what is hosted here: https://sedac.ciesin.columbia.edu/data/set/aqdh-o3-concentrations-contiguous-us-1-km-2000-2016 and are derived from the same statistical model and associated manuscript. I'm unfamiliar with the model specifics.
