sensortoolkit.reference._import_airnowtech

Module for importing raw AirNowTech data (table, unpivoted format) queried at month-long intervals at 1-hr recording frequency for PM2.5, PM10, O3, NO2, CO, relative humidity, temperature, wind speed, wind direction.

Data are sorted into PM, gas, and met dataframes and a table containing all AQS method codes is used to associate the recorded method code for data streams with the instrument used to make the measurement.

Processed dataframes for PM, Gas, and met are then written to separate monthly csv files where the index is the date and time in UTC.
