Reference Data Structures

Reference data are accessed via the ReferenceMonitor object instance. Following the Toco Toucan Quickstart Guide example, mention of reference variable below refers to the ReferenceMonitor object instantiated under the Testing Attribute Objects - The ReferenceMonitor Object section.

Accessing Reference Data

Both 1-hour and 24-hour averaged data sets are computed for FRM/FEM reference data, and data sets are organized by parameter classification (either PM for particulate matter, Gases for gaseous pollutants, or Met for meteorological parameters).

Tip

Parameter classifications for each SDFS parameter can be found in the Table of SDFS Parameters.

Reference datasets are access via the reference.data attribute, which stores pandas DataFrames for each parameter classification in a dictionary structure at both 1-hour and 24-hour averaged intervals:

{'PM': {'1-hour': pandas DataFrame object,
        '24-hour': pandas DataFrame object},
 'Gases': {'1-hour': pandas DataFrame object,
           '24-hour': pandas DataFrame object},
 'Met': {'1-hour': pandas DataFrame object,
         '24-hour': pandas DataFrame object}
}

Dataset Example

The first five rows of data for particulate matter measurements collected at the Burdens Creek monitoring site in RTP, NC, averaged to 1-hour intervals, and formatted as an SDFS dataset (accessed as reference['PM']['1-hour']) are shown at the following link: Example Reference Dataset
