Description
Returns a table of monitors and related metadata sites with the provided parameter, aggregated by latitude/longitude bounding box (_by_box) for bdate - edate time frame.
Usage
aqs_monitors_by_box(
parameter,
bdate,
edate,
minlat,
maxlat,
minlon,
maxlon,
return_header = FALSE
)
Arguments
parameter |
a character list or a single character string which represents the parameter code of the air pollutant related to the data being requested. |
bdate |
a R date object which represents that begin date of the data selection. Only data on or after this date will be returned. |
edate |
a R date object which represents that end date of the data selection. Only data on or before this date will be returned. |
minlat |
a R character object which represents the minimum latitude of a geographic box. Decimal latitude with north begin positive. Only data north of this latitude will be returned. |
maxlat |
a R character object which represents the maximum latitude of a geographic box. Decimal latitude with north begin positive. Only data south of this latitude will be returned. |
minlon |
a R character object which represents the minimum longitude of a geographic box. Decimal longitude with east begin positive. Only data east of this longitude will be returned. |
maxlon |
a R character object which represents the maximum longitude of a geographic box. Decimal longitude with east begin positive. Only data west of this longitude will be returned. Note that -80 is less than -70. |

a tibble or an AQS_Data Mart_APIv2 S3 object of monitors from a latitude/longitude bounding box (_by_box).
