Abstract

The global distribution of tropospheric ozone (O3) can be observed from a satellite-based instrument by spectrally isolating the pressure-broadened wings of strong O3 lines. The Fabry–Perot interferometer (FPI) provides high spectral resolution and high-throughput capabilities that are essential for performing such a measurement. Through proper selection of channel spectral regions, the FPI optimized for tropospheric O3 measurements can simultaneously observe a stratospheric component and thus the total O3 column abundance. We present a conceptual instrument design that involves a double-etalon fixed-gap series configuration FPI along with an ultranarrow bandpass filter to achieve single-order operation with an overall spectral resolution of approximately 0.068 cm-1, sampling the narrow 1054.2–1055.2 cm-1 spectral region within the strong 9.6-μm ozone infrared band from a nadir-viewing satellite configuration.
