What is Seasonal Abundance and Source Attribution of Carbonaceous Aerosols at Different Altitude of Mountainous Locations in Uttarakhand Himalaya about?
The present study reports on carbonaceous aerosol concentrations determined in total suspended particles (TSP) from three mountainous sites Devasthal (2450 m asl), Manora Peak (1940 m asl), and Bhimtal (1413 m asl) in Kumaun province of Uttarakhand Himalaya, India. The concentrations of organic carbon (OC) and elemental carbon (EC) were measured using IMPROVE\_thermal optical reflectance protocol. Results showed that TSP and carbonaceous species varied significantly and decreased with increasing altitudes. Seasonal/(diurnal) analysis indicated that TSP and carbonaceous species were significantly higher during summer than winter, while day-night-time variation was not statistically significant. Correlation analysis was performed between carbonaceous species and meteorological factors which showed significant positive correlations with planetary boundary layer, temperature, and solar radiation. OC and EC were noted to be strongly correlated (correlation coefficient > 0.8), implying similar emission sources and atmospheric processes. The ratios of OC/EC varied from 2.4 to 9.3 (Devasthal), 2.1 to 8.6 (Manora Peak) and 1.9 to 4.3 (Bhimtal), which suggested mixed sources of biomass burni
