Abstract: Tropical peatlands in Indonesia have been disturbed over decades and are a source of carbon dioxide (CO₂) into the atmosphere by peat respiration and peatland fire. With a portable solar spectrometer, we have performed measurements of column-averaged CO₂ dry-air molar mixing ratios, XCO₂ in Palangka Raya, Indonesia, and quantify the emission dynamics of the peatland with use of the data for weather, fire hotspot, ground water table, local airport operation visibility and weather radar images. Total emission of CO₂ from surface and underground peat fires as well as from peatland ecosystem is evaluated by day-to-day variability of XCO₂. We found that the peatland fire and the net ecosystem CO₂ exchange contributed with the same order of magnitude to the CO₂ emission during the non-El Niño Southern Oscillation year of July 2014-August 2015.
