openaq R client openaq hex logo

Project Status: Active – The project has reached a stable, usable state and is being actively developed. R-CMD-check Codecov test coverage

An R package for interacting with the OpenAQ API.

Installation

The package is available to install through Github. Use the pkg_install command from pak package.

install.packages("pak")

pak::pkg_install("openaq/openaq-r@*release")

Quickstart

For a full walkthrough on using openaq we recommend that you read through the “Introduction to openaq” vignette (vignette("openaq")). The following guide is a quick and minimal example to get you started.

  1. Register for an account at https://explore.openaq.org/register.
  2. Find your API key in the user account page.
  3. Save your API key as the OPENAQ_API_KEY environment variable . e.g. OPENAQ_API_KEY=yourkey in .Renviron. See help(openaq) for other ways to use and access your API key.

Now we can query OpenAQ for air quality monitoring locations. For this example we will query locations that measure PM2.5 near (with 10km) Antananarivo, Madagascar (-18.90848, 47.53751)

library(openaq)

locations <- list_locations(
    parameters_id = 2, 
    coordinates = c(latitude = -18.90848, longitude = 47.53751),
    radius = 10000
)

This returns a data frame that will look something like:

id name is_mobile is_monitor timezone countries_id country_name country_iso latitude longitude datetime_first datetime_last owner_name providers_id provider_name
41726 Antananarivo FALSE TRUE Indian/Antananarivo 182 Madagascar MG -18.90848 47.53751 2020-12-22 07:00:00 2025-01-17 20:00:00 Unknown Governmental Organization 119 AirNow
