An abnormal decrease in ozonesonde sensor signaloccurred during air-pollution study campaigns in November2011 and March 2012 in Mexico City MetropolitanArea (MCMA). Sharp drops in sensor signalaround 5 km above sea level and above were observedin November 2011, and a reduction of signal overa broad range of altitude was observed in the convectiveboundary layer in March 2012. Circumstantialevidence indicated that SO2 gas interfered withthe electrochemical concentration cell (ECC) ozonesensors in the ozonesonde and that this interferencewas the cause of the reduced sensor signal output. The sharp drops in November 2011 were attributedto the SO2 plume from Popocatépetl volcano southeastof MCMA. Experiments on the response of theECC sensor to representative atmospheric tracegases showed that only SO2 could cause the observedabrupt drops in sensor signal. The vertical profileof the plume reproduced by a Lagrangian particlediffusion simulation supported this finding. A neargroundreduction in the sensor signal in March 2012was attributed to an SO2 plume from the Tula industrialcomplex north-west of MCMA. Before and atthe time of ozonesonde launch, intermittent high SO2concentrations were recorded at ground-level monitoringstations north of MCMA. The difference betweenthe O3 concentration measured by the ozonesondeand that recorded by a UV-based O3 monitorwas consistent with the SO2 concentration recordedby a UV-based monitor on the ground. The verticalprofiles of the plumes estimated by Lagrangian particlediffusion simulation agreed fairly well with theobserved profile. Statistical analysis of the wind fieldin MCMA revealed that the effect Popocatépetl wasmost likely to have occurred from June to October,whereas the effect of the industries north of MCMA,including the Tula complex, was predicted to occurthroughout the year.
