Current Thermal IR orbital (TIR) instruments measure CO total column (TC)amounts in operational mode. The data are widely used for quantification of wildfires on a global scale. However, most of these data underestimate CO in the boundary layer. During the catastrophic fires in the Central Russia in July-August 2010, according to a top-down mass balance estimate and bottom-up inventory, 36-40 Tg CO have been released into the atmosphere. Two sun-viewing IR spectrometers, one in Moscow and another in its suburbs, measured CO TC during the fires. Ground-based local mixing ratios also were available. According to data presented in the report top-down inverse models using TIR data may underestimate amounts of CO TC emitted by wildfires up to 100%. Near IR sensors are expected to supply more accurate data.
