{weatherOz} facilitates access to and download of weather and climate data for Australia from Australian data sources. Data are sourced from from the Western Australia Department of Primary Industries and Regional Development (DPIRD) and the Scientific Information for Land Owners (SILO) API endpoints and the Australian Government Bureau of Meteorology’s (BOM) FTP server.
The package queries the APIs or an FTP server and returns data as a data frame or radar and satellite imagery in your R session. Observation data from DPIRD’s weather station network are available via the Weather 2.0 Open API initiative. SILO data is available from Queensland’s Long Paddock initiative (Jeffery et al. 2001) and are spatially and temporally complete, covering all Australia and few nearby islands (112 to 154 degrees longitude, -10 to -44 degrees latitude), with resolution 0.05° longitude by 0.05° latitude (approximately 5 km × 5 km). Visit the SILO website for more details about how the data is prepared and which climate data are available. Agriculture bulletins, radar imagery, satellite imagery and seven-day forecasts are available from the Bureau of Meteorology (BOM) via an anonymous FTP server.
Access to DPIRD API requires an API key. Apply for an API key by submitting the DPIRD API registration form. Access to the SILO API is conditioned to supplying a valid email address with the user query. Follow the API Terms and Conditions for the DPIRD and SILO APIs.
Observation data from the DPIRD’s weather station network is also available via a web interface. The data available is a mirror of the DPIRD Weather 2.0 API endpoints. Rainfall estimates are also available at virtual stations (i.e., where no observational data is present) and is sourced from the Doppler radar service provided by the Australian Government Bureau of Meteorology (BOM) under license.
Installation instructions
You can install the stable version of {weatherOz} from CRAN like so:
install.packages("weatherOz")
You can install the development version of {weatherOz} like so:
install.packages("weatherOz", repos = "https://ropensci.r-universe.dev")
A Note on API Keys
The examples in this README assume that you have stored your API key in your .Renviron file. {weatherOz} will prompt you to set up your API keys automatically if you haven’t. For more information on the preferred method for setting up your API keys, see Chapter 8 in “What They Forgot to Teach You About R” by Bryan et al. for more on storing details in your .Renviron if you are unfamiliar.
To get a DPIRD API key, you can use get_key() and it will direct you
to the form to request a key and provides instructions for setting it up
so that it’s available in your R session and {weatherOz} will
automatically find it. If you have already set up an API key, this will
return that value for you.
get_key(service = "DPIRD")
You only need to provide an e-mail address for the SILO API. Using
get_key() will provide you with instructions on what format to use in
your .Renviron so that {weatherOz} will auto-recognise it and if you
have already set up an API key, this will return that value for you.
get_key(service = "SILO")
Note that you do not need to do this separately, any function requiring an API key will prompt you if you don’t have one set.
Example 1
Source wind and erosion conditions for daily time interval from the DPIRD Weather 2.0 API.
library(weatherOz)
wd <- get_dpird_summaries(
station_code = "BI",
start_date = "20220501",
end_date = "20220502",
interval = "daily",
values = c(
"wind",
"erosionCondition",
"erosionConditionMinutes",
"erosionConditionStartTime"
)
)

Notes on Data and API Endpoints
Note that most of the data are not static and may be replaced with improved data. Also please note that SILO may be unavailable between 11am and 1pm (Brisbane time) each Wednesday and Thursday to allow for essential system maintenance.
Please also note that not all exposed endpoints of the DPIRD APIs have associated functions. Development is ongoing. While we are responsive to user requests, we don’t make any commitments about speed of delivery.
