airPollutionMelbourne

This repository was set up to contain code for preparing Melbourne data inputs required for air pollution model.

Overview

There is one script, monitoring site locations.R, which assesses the distance from air quality monitoring sites to roads, finds the nearest network links (accessible by car) to the monitoring stations, and classifies the monitoring sites based on descriptions at https://uk-air.defra.gov.uk/networks/site-types .

Input files

The code requires the following input files, which are available [to authorised users] at [insert location when known]. The code assumes that the input files are located in a data directory ("../data/") which sits beside the directory in which the script files are located .

File	Content
data/processed/annual_pm_no2_vic.xlsx	Location of air quality monitoring stations
data/processed/edgesMelbourne.gpkg	Edges and nodes making up the road network
data/processed/region.sqlite	Region: the study area for the JIBE project
data/processed/region_buffer.sqlite	Region, buffered: the region, plus a buffer to limit edge effects

Output file

The code produces the following output file, which is saved to the data/processed directory.

File	Content
monitoring site locations classified.csv	Distance from monitoring site locations to roads, nearest network links (car-accessible), and site classification.
