Eric Scott [aut] | Title: | Access Arizona Weather Data from the AZMet API |
|---|---|
| Description: | Provides R functions to access the Arizona Meteorological Network (AZMet) API. Functions are more than just "thin wrappers" and do some parsing of input parameters and wrangling of output data. |

station_id |
Station ID can be supplied as numeric vector (e.g.
|
start_date_time |
A length-1 vector of class POSIXct or character in YYYY-MM-DD HH:MM:SS format, in AZ time. If only a date (YYYY-MM-DD) is supplied, data will be requested starting at 00:00:01 of that day. |
end_date_time |
A length-1 vector of class POSIXct or character in
YYYY-MM-DD HH:MM:SS format, in AZ time. If only a date (YYYY-MM-DD) is
supplied, data will be requested through the end of that day (23:59:59).
Defaults to the current date and time if left blank and |
If neither start_date_time nor end_date_time are supplied, the
most recent datetime of data will be returned. If only start_date_time
is supplied, then end_date_time defaults to the current time. Supplying
only end_date_time will result in an error.
A tibble. For units and other metadata, see https://azmet.arizona.edu/about
If station_id is supplied as a vector, multiple successive calls to
the API will be made. You may find better performance getting data for all
the stations by leaving station_id blank and subsetting the resulting
dataframe. Only the most recent 48 hours of 15-minute data are stored in
the AZMet API.

Retrieves accumulated heat units and reference evapotranspiration units from the Arizona Meteorological Network API. By default, returned values are cumulative since January 1 of the current year.
