PSI stands for 'Pollutant Standards Index'. It is an index to provide accurate and easily understandable information about daily levels of air quality

PSI is computed based on 24-hour/3-hour average of PM2.5 concentration levels, among other pollutants. PM2.5 is the dominant pollutant during haze episodes.

The 1-hour PM2.5 concentrations reflect the PM2.5 levels averaged over one hour, and can give you an indication of the current air quality. However, the 1-hour PM2.5 concentration levels can be volatile and tend to fluctuate over the day especially during periods of transboundary haze.

Short-term fluctuations will also be very heavily influenced by weather conditions. For example, there could be a short period of transiently high PM2.5, only to improve rapidly in the next one to two hours. Therefore, if you wish to use the 1-hour PM2.5 concentration, it is best used as a guide to adjust your immediate activities
