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:
