The question whether the total ozone mapping spectrometer (TOMS) is capable of measuring ozone levels in a solid rocket motor plume is examined. Simulated measurements were computed for a chemical kinetics and dispersion model of a Titan IV plume. The principal disadvantage of TOMS for measuring local plume ozone levels is that the detection field-of-view is typically much larger than the column area for ozone loss. A secondary problem is attenuation of backscattered light by plume species and particles that can distort the ozone measurement. ¿ American Geophysical Union 1996
