Calculate hourly NowCast-based AQI values

Source: R/monitor_aqi.R

Nowcast and AQI algorithms are applied to the data in the monitor object. A modified mts_monitor object is returned whre values have been replaced with their Air Quality Index equivalents. See monitor_nowcast.

monitor_aqi(
  monitor,
  version = c("pm", "pmAsian", "ozone"),
  includeShortTerm = FALSE,
  NAAQS = c("PM2.5_2024", "PM2.5")
)

Arguments

monitor

mts_monitor object.

version

Name of the type of nowcast algorithm to be used.

includeShortTerm

Logical specifying whether to alcluate preliminary NowCast values starting with the 2nd hour.

NAAQS

Version of NAAQS levels to use. See Note.

Value

A modified mts_monitor object containing AQI values. (A list with meta and data dataframes.)

Note

On February 7, 2024, EPA strengthened the National Ambient Air Quality Standards for Particulate Matter (PM NAAQS) to protect millions of Americans from harmful and costly health impacts, such as heart attacks and premature death. Particle or soot pollution is one of the most dangerous forms of air pollution, and an extensive body of science links it to a range of serious and sometimes deadly illnesses. EPA is setting the level of the primary (health-based) annual PM2.5 standard at 9.0 micrograms per cubic meter to provide increased public health protection, consistent with the available health science. See PM NAAQS update.
