airzone_metric: Calculate the airzone metric

In bcgov/rcaaqs: Tools to implement CAAQS analysis for air quality

Calculate the airzone metric

Description

Calculate the metrics for each airzone based on station-level results. Determines the CAAQS achievement levels and CAAQS management levels for each airzone and reports on the representative stations for these metrics in each airzone.

Usage

airzone_metric(
  data,
  n_years = "n_years",
  az = "airzone",
  station_id = "ems_id",
  ambient_metric_val = "metric_value_ambient",
  ambient_caaqs = "caaqs_ambient",
  excluded = "excluded",
  mgmt_metric_val = "metric_value_mgmt",
  mgmt = "mgmt_level",
  keep = NULL
)

Arguments

data	The dataframe
n_years	The column containing the number of years each 3yr avg is based on
az	The airzone column
station_id	The column containing the unique station id
ambient_metric_val	The column containing the ambient CAAQS metric for individual stations
ambient_caaqs	The column containing the CAAQS achievement levels for individual stations
excluded	Logical vector indicating if ambient data was excluded for calculating the CAAQS management levels
mgmt_metric_val	The column containing the management CAAQS metric for individual stations
mgmt	The column containing the CAAQS management levels for individual stations
keep	Character vector specifying the columns in the input data that you would like to retain in the output data frame.

Value

A dataframe with 9 columns: airzone, number of years in calculation, ambient CAAQS metric value, CAAQS achievement levels, ambient reporting station id, logical vector indicating if ambient data was excluded for management calculations, management CAAQS metric value, CAAQS management levels, and management reporting station id.
