DataFrame | AQSAPI_V2

Notes

The AQS API only allows for a single year of quarterly summary to be retrieved at a time. This function conveniently extracts date information from the bdate and edate parameters then makes repeated calls to the AQSAPI retrieving a maximum of one calendar year of data at a time. Each calendar year of data requires a separate API call so multiple years of data will require multiple API calls. As the number of years of data being requested increases so does the length of time that it will take to retrieve results. There is also a 5 second wait time inserted between successive API calls to prevent overloading the API server. This operation has a linear run time of /(Big O notation: O/(n + 5 seconds/)/).

Also Note that for quarterly data, only the year portion of the bdate and edate are used and all 4 quarters in the year are returned.

Examples

Return a DataFrame containing ozone quarterly summaries in the vicinity of central Alabama for each quarter in between 2015 - 2017:
