azmetr

The goal of azmetr is to provide programmatic access to the Arizona Meteorological Network (AZMet) API in R.

Installation

You can install the development version of azmetr from r-universe:

install.packages('azmetr', repos = c('https://uace-azmet.r-universe.dev', 'https://cloud.r-project.org'))

Alternatively, you can install a development version directly from GitHub with the remotes package:

# install.packages("remotes")
remotes::install_github("uace-azmet/azmetr")

Example

For the most recent data from all stations, run functions without any arguments:

library(azmetr)

az_15min()
az_daily()
az_heat()
az_hourly()
az_lw15min()
az_lwdaily()

Because azmetr uses the httr2 package to handle API requests, you can wrap any azmetr function with with_verbosity() to get more detailed logging of the actually HTTP requests and response headers. For example:

httr2::with_verbosity(az_daily())
#> Querying data from 2026-05-19
#> -> GET /v1/observations/daily/*/*/* HTTP/2
#> -> Host: api.azmet.arizona.edu
#> -> User-Agent: azmetr (https://github.com/uace-azmet/azmetr)
#> -> Accept-Encoding: deflate, gzip
#> -> Accept: application/json
#> -> 
#> <- HTTP/2 200 
#> <- date: Wed, 20 May 2026 21:49:18 GMT
#> <- content-type: application/json
#> <- server: -
#> <-
