Variation and dispersal of PM₁₀ and PM_2.5 during COVID-19 lockdown over Kolkata metropolitan city, India investigated through HYSPLIT model.

ABSTRACT: The higher concentration of PM₁₀ and PM_2.5 in the lower atmosphere is severely harmful for human health and it also makes visibility diminution along with weather and climate modifications. The main objective is to find out the spatiotemporal variation and dispersal of PM₁₀ and PM_2.5 along with COVID-19 infection in the dusty city Kolkata. The consecutive two years PM₁₀ and PM_2.5 data of different stations have been obtained from State Pollution Control Board, Govt. of West Bengal. Forward trajectory analysis has been done through HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) model to find the path and direction of air particles. The result showed that the various meteorological or environmental factors (
