What is Severe haze events in the Indo-Gangetic Plain during post-monsoon: Synergetic effect of synoptic meteorology and crop residue burning emission about?

In recent years, the frequent occurrence of haze events in the Indo-Gangetic Plain (IGP) during crop residue burning period has caused a serious reduction in atmospheric visibility and deteriorated air quality. The present study is carried out to investigate the haze event observed in IGP in Nov 2017 using ground-based observations, satellite data and synoptic meteorology to understand the possible factors responsible for haze formation. PM (particulate matter with aerodynamic diameter ≤ 2.5 μm) concentrations and Air Quality Index (AQI) at two sites (Agra and Delhi) situated in the central Indo-Gangetic Plain (CIGP) showed a sudden increase in PM concentrations and deteriorated air quality during 7-14 Nov. To monitor the variation of particulate matter (PM) in IGP, PM and PM (particulate matter with aerodynamic diameter ≤ 10 μm) concentrations were monitored at 22 stations in 12 cities of IGP during 1-15 Nov which also showed an increase in PM concentrations during haze event (7-14 Nov). Crop residue burning activities in north-west Indo-Gangetic Plain (NW-IGP) were observed during haze event. Synoptic weather conditions of IGP identified using geopotential height and wind at 700
