Get DPIRD Weather Data in Summarised Formats

Fetch nicely formatted individual station weather summaries from the DPIRD Weather 2.0 API.

Usage

get_dpird_summaries(
  station_code,
  start_date,
  end_date = Sys.Date(),
  interval = c("daily", "15min", "30min", "hourly", "monthly", "yearly"),
  values = "all",
  include_closed = FALSE,
  api_key
)

Arguments

station_code

A character string of the DPIRD station code for the station of interest. Station codes are available from the get_stations_metadata() function.

start_date

A character string or Date object representing the beginning of the range to query in the format “yyyy-mm-dd” (ISO8601). Data returned is inclusive of this date.

end_date

A character string or Date object representing the end of the range query in the format “yyyy-mm-dd” (ISO8601). Data returned is inclusive of this date. Defaults to the current system date.

interval

A character string that indicates the time interval to monthly or yearly. For intervals shorter than 1 day, the time period covered will be midnight to midnight, with the end_date time interval being before midnight - hour/minute values are for the end of the time period. Data for shorter intervals (15min, 30min) are available from January of the previous year.

values

A character string with the type of summarised weather to return. See Available Values for a full list of valid values. Defaults to all with all available values being returned.

include_closed

A Boolean value that defaults to FALSE. If set to TRUE the query returns closed and open stations. Closed stations are those that have been turned off and no longer report data. They may be useful for historical purposes. Only set to TRUE to fetch data from closed stations.

api_key

A character string containing your API key from DPIRD, https://www.agric.wa.gov.au/web-apis, for the DPIRD Weather 2.0 API.

Value

a data.table with station_code and the date interval queried together with the requested weather variables in alphabetical order. The first ten columns will always be:

• station_code,

• station_name,

• longitude,

• latitude,

• year,

• month,

• day,

• hour,

• minute, and if month or finer is present,

• date (a combination of year, month, day, hour, minute as appropriate).

Note

Please note this function converts date-time columns from Coordinated Universal Time ‘UTC’ to Australian Western Standard Time ‘AWST’.

Start Dates

The earliest available data start from August of 2000 for Vasse, “VA”.

Column Name Details

Column names are converted from the default returns of the API to be snake_case formatted and where appropriate, the names of the values that are analogous between SILO and DPIRD data are named using the same name for ease of interoperability, e.g., using rbind() to create a data.table that contains data from both APIs. However, use with caution and don't mix datasets of different time-steps, i.e., this function gets many summary values not just “daily” time-step data. The functions that access the SILO API only provide access to daily data, so don't mix (sub)hourly, monthly or yearly data from DPIRD with SILO.
