“…Similar to our results, Vadrevu et al . [] have observed that the burning activities are well associated with AOD variations over the northwest IGP. The max MODIS AODs are similar in magnitude to those reported over Patiala in October and November 2008 (2.65 and 1.71, respectively) [ Sharma et al ., ], while AODs from agricultural fires above 2.0 were found over Zambia [ Eck et al ., , ], Northeast China and Korea [ Kim et al ., ], and Djougou, Benin [ Pelon et al ., ].…”

Aerosol emissions from biomass burning are of specific interest over the globe due to their strong radiative impacts and climate implications. The present study examines the impact of paddy crop residue burning over northern India during the postmonsoon (October-November) season of 2012 on modification of aerosol properties, as well as the long-range transport of smoke plumes, altitude characteristics, and affected areas via the synergy of ground-based measurements and satellite observations. During this period, Moderate Resolution Imaging Spectroradiometer (MODIS) images show a thick smoke/hazy aerosol layer below 2-2.5 km in the atmosphere covering nearly the whole Indo-Gangetic Plains (IGP). The air mass trajectories originating from the biomass-burning source region over Punjab at 500 m reveal a potential aerosol transport pathway along the Ganges valley from west to east, resulting in a strong aerosol optical depth (AOD) gradient. Sometimes, depending upon the wind direction and meteorological conditions, the plumes also influence central India, the Arabian Sea, and the Bay of Bengal, thus contributing to Asian pollution outflow. The increased number of fire counts (Terra and Aqua MODIS data) is associated with severe aerosol-laden atmospheres (AOD 500 nm > 1.0) over six IGP locations, high values of Ångström exponent (>1.2), high particulate mass 2.5 (PM 2.5 ) concentrations (>100-150 μgm À3 ), and enhanced Ozone Monitoring Instrument Aerosol Index gradient (~2.5) and NO 2 concentrations (~6 × 10 15 mol/cm 2 ), indicating the dominance of smoke aerosols from agricultural crop residue burning. The aerosol size distribution is shifted toward the fine-mode fraction, also exhibiting an increase in the radius of fine aerosols due to coagulation processes in a highly turbid environment. The spectral variation of the single-scattering albedo reveals enhanced dominance of moderately absorbing aerosols, while the aerosol properties, modification, and mixing atmospheric processes differentiate along the IGP sites depending on the distance from the aerosol source, urban influence, and local characteristics.

“…10(d)) during 12 May-16 May emphasized the occurrence of some special anthropogenic or natural events (burning activities). This sudden increase in fine mode aerosol concentration can be attributed to the smoke originating from agricultural crop residue (wheat straw) burning activities or vegetation fire as reported by Vadrevu et al (2011Vadrevu et al ( , 2012 and Mishra and Shibata (2012b). To confirm our hypothesis, we used level 2 version 3.01 data (night-time) for the aerosol subtypes and aerosol backscatter (β 532 ) from space-borne lidar CALIOP (Omar et al, 2009) on 12 th May, 2009 (Fig.…”

“…Also, satellite measurements of FRP released rate can be associated with aerosol optical depth (AOD) to provide regional smoke emission coefficients [19]. Studies analyzing the biomass burning patterns using FRP for global characterization were be performed by Ichoku et al [20], for Africa by Roberts et al [21], Roberts and Wooster [22] and for Asia by Vadrevu et al [23].…”

Land cover plays a major role in many biogeochemical models that represent processes and connections with terrestrial systems; hence, it is a key component for public decisions in ecosystems management. The advance of remote sensing technology, combined with the emergence of new operational products, offers alternatives to improve the accuracy of environmental monitoring and analysis. This work uses the GLOBCOVER, the Vegetation Continuous Field (VCF), MODIS Fire Radiative Power (FRP) and the Tropical Rainfall Measuring Mission (TRMM) remotely sensed databases to analyze the biomass burning distribution, the land use and land cover characteristics and the percent of tree cover in South America during the years 2000 to 2005. Initially, GLOBCOVER was assessed based on VCF product, and subsequently used for quantitative analysis of the spatial distribution of the South America fires with the fire radiative power (FRP). The results show that GLOBCOVER has a tendency to overestimate forest classes and to underestimate urban and mangroves areas. The fire quantification based on GLOBCOVER product shows that the highest incidence of fires can be observed in the arc of deforestation, located in the Amazon forest border, with vegetation cover composed mainly of broadleaved evergreen or semi-deciduous forest. A time series analysis of FRP database indicates that biomass burning occurs mainly in areas of broadleaved evergreen or semi-deciduous forest and in Brazilian Cerrado associated with grassland management, agricultural land clearing and with the deforestation of Amazon tropical rainforest. Also, variations in FRP intensity and
