“…A series of papers have discussed the impact of the Southeastern Asia fires on the composition and chemistry of the atmosphere (Fujiwara et al, 1999;Hauglustaine et al, 1999;Matsueda and Inoue, 1999;Nakajima et al, 1999;Rinsland et al, 1999;Sawa et al, 1999;Tsutsumi et al, 1999). The results of these studies are summarized below.…”

“…Thus, in terms of explaining the observed atmospheric CO anomalies, less total carbon emissions are required when CO emissions factors are large. Aircraft measurements near the 1997 Indonesian fires show very low NO x (emitted mostly during a flaming stage of a fire) to CO (emitted mostly during the smoldering stage of a fire) ratios, provide regional-scale evidence for smoldering combustion (28), and support ground-based measurements that implicate peat burning as the primary source of emissions (29). However, other aircraft measurements (30) report CO:CO 2 ratios near Indonesia of 0.089 that were similar to (or even lower than) the values used here (Table 1).…”

During the 1997 to 1998 El Niño, drought conditions triggered widespread increases in fire activity, releasing CH 4 and CO 2 to the atmosphere. We evaluated the contribution of fires from different continents to variability in these greenhouse gases from 1997 to 2001, using satellite-based estimates of fire activity, biogeochemical modeling, and an inverse analysis of atmospheric CO anomalies. During the 1997 to 1998 El Niño, the fire emissions anomaly was 2.1 ± 0.8 petagrams of carbon, or 66 ± 24% of the CO 2 growth rate anomaly. The main contributors were Southeast Asia (60%), Central and South America (30%), and boreal regions of Eurasia and North America (10%).

“…Local land cover type and regional meteorology influence the atmospheric aerosol environment at a given location (Schafer et al, 2008). Aerosol properties resulting from biomass burning in South America and Africa might be different from Asia which mostly originated from peatland (Gras et al, 1999;Matsueda and Inoue, 1999;Sawa et al, 1999;Fujii et al, 2014), while fire in South America and Africa likely occurred in Boreal Forest and savannah Holben et al, 2001). In addition, human activities influence the aerosol environment by releasing amount of particulate and gas species to the atmosphere through land cover change, combustion of fossil fuel for transportation and energy (Artaxo et al, 1994;.…”

The optical properties of aerosol could describe the potential source of prevalent pollutants of certain area. With the annual occurrences of biomass burning over the peat swamp forest, the study of aerosol characters in Central Kalimantan province becomes important. Aerosols from Aerosol Robotic Network (AERONET) data network combine with some environmental parameters, i.e., rainfall, visibility, surface humidity and hotspot number are investigated. Here we use the data from 2012 to 2014 collected from AERONET in Palangkaraya. We found a strong relationship between aerosol properties and environmental parameters (rainfall, hotspot number, visibility). Variability of aerosol properties such as aerosol optical depth (AOD), Angstrom exponent number, and its fine mode are consistent with the dry period between August and October when most fire episodes occur. In fact, the increase of aerosol loading occurs mostly when the monthly rainfall reaches below 150 mm month -1 (dry period), as the cut off number of our analyses. Considerable reduction of visibility below 500 m occurs whenever AOD is above 3.0. During observation period, we found that aerosol sources at this location originate from dust, marine aerosol, continental and urban aerosol, and biomass burning. The biomass burning aerosol gave a substantially high AOD values that reach almost 6.0 and fine feature as an indication of highly concentrated smoke from peatland source. Moreover, smouldering combustion from peat land is characterized by high value of single scattering albedo observed in the location.
