pyaurn 0.0.9

Package to import AURN air quality data from DEFRA UK AIR site

PyAURN -

This is a rework of the original function, utilising pyreadr instead of rpy2. This negates having a local installation of R, and therefore can remain a python only configuration.

This is a simple Python package to import data from the UK Automatic Urban Rural Network - an air pollution network run by the UK government.

This is a Python port of a couple of functions of the openair R package. This R package relies on data provided as a set of .RData files on the Defra website, specifically designed for use by the openair project. This Python package relies on the same data.

Getting started

Install the via pip:

pip install pyaurn

Example quickstart functions in the package as below:

from pyaurn import importAURN, importMeta, timeAverage

# Download metadata of site IDs, names, locations etc
metadata = importMeta()

# Download 4 years of data for the Marylebone Road site
# (MY1 is the site ID for this site)
# Note: range(2016, 2022) will produce a list of six years: 2016, 2017, 2018, 2019, 2020, and 2021. Alternatively define a list of years to use eg. [2016,2017,2018,2019,2020,2021]
data = importAURN("MY1", range(2016, 2022))

# Group the DataFrame by a frequency of monthly, and the statistic mean(). 
data_monthly = timeAverage(data,avg_time="month",statistic="mean")

Future developments

• integrate other openair functions
• open to suggestions (please leave enhancement tag in Issues)
