The data files are categorized by three averaging duration:

5 minute data
Rolling one hour data

Each data file will have data for all Rule 1180 monitoring stations with all the pollutants being measured by each station. All files are in comma separated variable (CSV) format that are compressed to save space.

Note: The files will contain a large number of rows and appropriate software that can handle this number of rows will be needed to work with the data.

Each table entry has the file name, linked to the file and the size of the (zipped) file.
