Variable descriptions and usage

These are all the available variables that can be used with various functions exported from the pyaqsapi library listed alphabetically. Not all of these variables are used with every function, and not all of these parameters are required. See the :ref: pyaqsapi functional families section to see which parameters are used with each function.

  • AQSobject:

* aqs_sign_up
These functions are used to sign up with Data Mart and to store credential

information to use with pyaqsapi. The aqs_sign_up function takes one parameter:

  • email:

The aqs_credentials function takes two parameters:

  • username:

  • key:

Data Mart API metadata functions

The functions included in this family of functions are:

* aqs_isavailable
* aqs_knownissues
* aqs_fields_by_service
* aqs_revisionhistory

These functions return Data Mart meta data

The aqs_isavailable function takes no parameters and returns a table which details the status of the AQS API.

The aqs_fields_by_service function takes one parameter, service, which is a character object which represents the services provided by the AQS API. For a list of available services see Air Quality System (AQS) API - Services Overview

The aqs_knownissues function takes no parameters and Returns a table of any known issues with system functionality or the data. These are usually issues that have been identified internally and will require some time to correct in Data Mart or the API. This function implements a direct API call to Data Mart and returns data directly from the API. Issues returned via this function do not include any issues from the pyaqsapi package.

The aqs_revisionhistory function is used to query Data Mart for the change history to the API.

Data Mart API list functions

The functions included in this family of functions are:

* aqs_cbsas,
* aqs_classes,

List functions return the API status, API options or groupings that can be used in conjunction with other API calls. By default each function in this category returns results as a DataTable. If return_header parameter is set to True a AQSAPI_v2 object is returned instead.

aqs_cbsas returns a table of all available Core Based Statistical Areas (cbsas) and their respective cbsa codes.

aqs_states takes no arguments and returns a table of the available states and their respective state FIPS codes.

aqs_sampledurations() aqs_sampledurations takes no arguments and returns a table of the available sample duration code used to construct other requests.

aqs_classes takes no arguments and returns a table of parameter classes (groups of parameters, i.e. “criteria” or “all”).

aqs_counties_by_state() aqs_counties_by_state takes one parameter, stateFIPS, which is a two digit state FIPS code for the state being requested represented as a character object and returns a table of counties and their respective FIPS code for the state requested. Use aqs_states to receive a table of valid state FIPS codes.

aqs_sites_by_county takes two parameters, stateFIPS, which is a two digit state FIPS code for the state being requested and county_code which is a three digit county FIPS code for the county being requested, both stateFIPS and county_code should be encoded as a character object. This function returns a table of all air monitoring sites with the requested state and county FIPS code combination.

aqs_mas takes no parameters and returns an AQSAPI_V2 object containing a table of monitoring agencies (MA).

Data Mart aggregate functions

Note

AQS Data Mart API restricts the maximum amount of monitoring data to one full year of data per API call. These functions are able to return multiple years of data by making repeated calls to the API. Each call to the Data Mart API will take time to complete. The more years of data being requested the longer pyaqsapi will take to return the results.

These functions retrieve aggregated data from the Data Mart API and are grouped by how each function aggregates the data. There are 5 different families of related aggregate functions. These families are arranged by how the Data Mart API groups the returned data, bysite, bycounty, bystate, by<latitude/longitude bounding box> (bybox) and by<core based statistical area> (bycbsa). Within each family of aggregated data functions there are functions that call on the 10 different services that the Data Mart API provides. All Aggregate functions return a pandas DataFrame by default. If the return_Header parameter is set to True an AQSAPI_V2 object is returned instead.

These fourteen services are:

  1. Monitors:

    Returns operational information about the samplers (monitors) used to collect the data. Includes identifying information, operational dates, operating organizations, etc. Functions using this service contain monitors in the function name.

  2. Sample Data:

Functions using this service contain sampledata in the function name. All Sample Data functions accept two additional, optional parameters; cbdate and cedate.

    • cbdate:

      a date object which represents a “beginning date of last change” that indicates when the data was last updated. cbdate is used to filter data based on the change date. Only data that changed on or after this date will be returned. This is an optional variable which defaults to None.

    • cedate:

      a date object which represents an “end date of last change” that indicates when the data was last updated. cedate is used to filter data based on the change date. Only data that changed on or before this date will be returned. This is an optional variable which defaults to None.

    • duration:

      an optional character string that represents the parameter duration code that limits returned data to a specific sample duration. The default value of None results in no filtering based on duration code. Valid durations include actual sample durations and not calculated durations such as 8 hour CO or $O_3$ rolling averages, 3/6 day PM averages or Pb 3 month rolling averages. Refer to aqs_sampledurations() for a list of all available duration codes.
