Interactive comment on “Chemical composition of pre-monsoon air in the Indo–Gangetic Plain measured using a new PTR-MS and air quality facility: high surface ozone and strong influence of biomass burning” by V. Sinha et al
This paper describes a new high quality atmospheric chemistry observation station in a very important part of the world where very little data is available. The station is impacted by many types of globally important undersampled sources such as cooking fires, agricultural burning, and dust storms. It is also impacted by more conventionally sampled urban and biogenic sources, but in a new conte...

One seventh of the world’s population lives in the Indo-Gangetic Plain (IGP) and the fertile region sustains agricultural food crop production for much of South Asia, yet it remains one of the most under-studied regions of the world in terms of atmospheric composition and chemistry. In particular, the emissions and chemistry of volatile organic compounds (VOCs) that form surface ozone and secon...
متن کاملOrganic molecular tracers in the atmospheric aerosols from Lumbini, Nepal, in the northern Indo-Gangetic Plain: Influence of biomass burning
To better understand the characteristics of biomass burning in the northern Indo-Gangetic Plain (IGP), total suspended particles were collected in a rural site, Lumbini, Nepal, during April 2013 to March 2014 and analyzed for the biomass burning tracers (i.e., levoglucosan, mannosan, vanillic acid). The annual average concentration of levoglucosan was 734± 1043 ng m−3 with the maximum seasonal ...
متن کاملDiurnal Variability in Secondary Organic Aerosol Formation over the Indo- Gangetic Plain during Winter Using Online Measurement of Water-Soluble Organic Carbon
Understanding the secondary organic aerosol (SOA) formation is among most important topics in the field of aerosol research because its poor understanding leads to large uncertainty in the assessment of aerosol effects on air quality and climate. This study reports the diurnal and temporal variability in SOA formation over a site (Patiala: 30.2°N, 76.3°E, 249 m amsl) located in the Indo-Gangeti...
متن کاملDaytime Ozone Variation in Surface Air in a Subtropical Mangrove Estuary at Manakudy, South India
Surface ozone (SOZ) can be very harmful if it exceeds the threshold limit. It can accumulate over sea and can return back to the land along with the breeze. Rural and vegetation rich areas often record elevated levels of surface ozone because of the variations in Volatile Organic Compound (VOC) levels, wind velocity and direction. Similarly methane is also an important greenhouse gas and plays ...
