Investigation on the Relation between Zenith Total Delay and Atmospheric Particulate Matter (PM2.5)

The occurrence of different phenomenon like forest fire give rise to increment in aerosol content of air, generally referred to as Particulate Matter (PM). The increment of PM concentration has both health and climate related hazards. Increased PM values can bring a change in water vapor content and humidity of air which causes the increment in atmospheric delays. In this paper we investigate the relation between PM concentration and Zenith Total Delay (ZTD) delays. Preliminary results show a positive correlation between the two.
