Satellite- And Ground-Based Co Total Column Observations Over 2010 Russian Fires: Accuracy Of Top-Down Estimates Based On Thermal Ir Satellite Data, Leonid Yurganov

Leonid Yurganov

CO total column data are presented from three space sounders and two ground-based spectrometers in Moscow and its suburbs during the forest and peat fires that occurred in Central Russia in July–August 2010. Also presented are ground-based in situ CO measurements. The Moscow area was strongly impacted by the CO plume from these fires. Concurrent satellite- and ground-based observa- tions were used to quantify the errors of CO top-down emis- sion estimates. On certain days, CO total columns retrieved from the data of the space-based sounders were 2–3 times less than those obtained from the ground-based sun-tracking spectrometers. The depth …
