How is this data produced?
This dataset presents monthly concentrations of various air pollutants, including carbon monoxide (CO), nitrogen dioxide (NO²), ozone (O³), particulate matter (PM₁₀, PM₂.₅), and sulfur dioxide (SO²). The data is tabulated from hourly observational data collected from monitoring stations across Malaysia.
What caveats I should bear in mind when using this data?
A small minority of values in 2017 are null due to inavailability of data.
