Analysis Tools

Openair provides free, open-source and innovative tools to analyse, interpret and understand air pollution data using R; a free and open-source programming language designed for the analysis of data. The Openair tools available on this website can be used to readily perform complex and innovative analysis of current and archived air pollutant data from the ArRiyadh Air Quality Monitoring Network, allowing powerful data visualisation and interrogation capabilities for this data for the first time. This website makes it straightforward to download these graphical outputs from Openair in document ready formats.

The Openair package was primarily developed for the analysis of air pollution datasets with the ability to handle high volumes of data.  A further strength of the Openair tools is that they also allow data to be conditioned by one or more variables. For example, plots can be produced that show the inter-relationships between air pollutants and meteorological parameters, or temporal trends which vary over different time periods such as hour of day, day of week, month of year, and so on, that would otherwise not be apparent.

The Openair website contains a full description of all functions as well as downloads and guidance to help users apply the tools to their own data. The ArRiyadh Development Authority website provides simplified web access to a customised selection of the Openair tools, updated to include recent developments in Openair including tools that require meteorological data in order to run.
