Limb infrared spectral measurements of the 9.6‐µm mesospheric ozone airglow were made by the Cryogenic Infrared Radiance Instrumentation for Shuttle (CIRRIS‐1A) during one flight of the space shuttle Discovery (April 28 th to May 6 th 1991). A significant difference between ozone nightglow and dayglow is observed. The measured spectrally integrated ozone ν 3 fundamental band radiance profile is used to retrieve the ozone (ν 3 = 1) excited state density. Modeled ozone (ν 3 = 1) vibrational temperatures are used to infer the total ozone density. Night and day ozone abundance profiles inferred from ozone 9.6‐µm infrared spectral emissions and comparisons with photochemical model calculations are reported. The observed ozone abundance is significantly larger than predicted by the photochemical model.
