monitor_load(
  startdate = NULL,
  enddate = NULL,
  timezone = NULL,
  archiveBaseUrl = paste0("https://airfire-data-exports.s3.us-west-2.amazonaws.com/",
    "monitoring/v2"),
  archiveBaseDir = NULL,
  QC_negativeValues = c("zero", "na", "ignore"),
  epaPreference = c("airnow", "epa_aqs")
)

Arguments

startdate	Desired start datetime (ISO 8601).
enddate	Desired end datetime (ISO 8601).
timezone	Olson timezone used to interpret dates.
archiveBaseUrl	Base URL for monitoring v2 data files.
archiveBaseDir	Local base directory for monitoring v2 data files.
QC_negativeValues	Type of QC to apply to negative values. files are available from both 'epa' and 'airnow'.
