Working with South Coast Data article

[jonathancallahan]

We maintain an archive of pre-generated data files for sensors associated with the South Coast Air Quality Management District (SCAQMD). This is the easiest data to work with and we should have an article aimed at non-R programmers. The goal is to provide a short introduction and then some simple recipe-style R code that creates plots answering basic questions.

You should explore a little to find sensors that demonstrate the following:

• Intrusion of wildfire smoke last September -- Bay Area?
• July 4 fireworks -- downtown LA
• sensor agreeing with nearby monitor -- pat_externalFit()
• sensor failure -- pat_internalFit()
• something else?
