The impact of forest and land fires on the atmospheric environment can be classified into three components, namely ambient air quality, its contribution to greenhouse gases, and microclimate change. Each component has a different method for assessing and measuring the magnitude of its impact. The aim of the study is to obtain quantitative methods to assess the magnitude of the impact of forest and land fires on the atmospheric environment so that they can be used for the valuation of environmental losses. The magnitude of the impact of the air quality component is measured based on the Air Pollution Index (ISPU) and visibility, the component of the greenhouse gas is assessed by approaching the amount of GHG emissions and / or loss of carbon stocks, while changes in the microclimate by assessing changes in the level of thermal comfort. Gas and particulate emissions values of forest and land fires use the carbon mass balance approach and emission factors. Analysis of air pollution dispersion is conducted use the Gaussian model, with case study is the incidence of land fires in oil palm plantations located in Kayuagung sub-district, Ogan Komering Ilir Regency, South Sumatra Province in 2015, 2016 and 2017. The data used in this study consisted of Landsat 8 satellite imagery, MODIS and VIIRS Hotspots, measurements of vegetation biomass in the field, organic C-peat and climate data during fires. The results of the assessment show that land fires covering 551 ha in 2015, 59 ha in 2016 and 253 ha in 2018 have resulted in changes in the air pollutant standard index in Kayuagung from the medium category (ISPU PM10 = 75) to very unhealthy (ISPU PM10 = 272) in 2015, unhealthy (ISPU CO = 116) in 2016 and very unhealthy (ISPU CO = 205) in 2018. Visibility in an area of about 500-600 meters in the direction of the wind from the fire’s location was less than 1 km with PM10 of more than 176 µg m −3 . The contribution of GHGs to each fire’s year is 26.8, 2.8 and 12.3 kilo tons of CO 2 e consist of CO 2 and CH 4 . The results of this study can be used to quantify the magnitude of the land fires impact on the atmospheric environment.
