Load PurpleAir synoptic data

A pre-generated pa_synoptic object will be loaded for the given date. These files are generated each day and provide a record of all currently installed PurpleAir sensors for the day of interest. With default arguments, this function will always load data associated with the most recent pre-generated file -- typically less than one hour old.

The datestamp can be anything that is understood by lubrdiate::ymd() including either of the following recommended formats:

"YYYYmmdd"
"YYYY-mm-dd"

By default, the host computer's date is used.

The pas object for a specific hour may be loaded by specifying datestamp = "YYYYmmddHH".

pas_load(
  datestamp = NULL,
  retries = 30,
  timezone = "America/Los_Angeles",
  archival = FALSE,
  verbose = TRUE
)

Arguments

datestamp: Local date string in valid YYYY-mm-dd format. See description.
retries: Max number of days to go back and try to load if requested date cannot be retrieved.
timezone: Timezone used to interpret datestamp.
archival: Logical specifying whether a version should be loaded that includes sensors that have stopped reporting.
verbose: Logical controlling the generation of warning and error messages.

Value
