Paper Abstract

Space-based observation of tropospheric pollution has been identified as an important measurement to be included in Earth science missions of the 21st century. This presentation will summarize on-going efforts focused on enabling such a new capability, a high-priority atmospheric science mission for the measurement of tropospheric ozone from a space-based platform, through the implementation of Fabry-Perot interferometry. The measurement technique involves a double-etalon series configuration FPI along with an ultra-narrow bandpass filter to achieve single-order operation with an overall spectral resolution of approximately .068 cm-1, sampling a narrow spectral region within the strong 9.6 micrometers ozone infrared band form a nadir-viewing satellite configuration. Current research efforts are focusing on technology development and demonstration activities to address technology drivers associated with this measurement concept. To this end we have developed a small-scale, modular, double-etalon prototype FPI for laboratory characterization and testing, modelled the instrument optical configuration, and performed R and D associated with an etalon optical control scheme. This presentation will cover advancements pertaining to all aspects of this effort, however, emphasis will be placed on integration and testing activities associated with the laboratory prototype FPI. This will include multichannel operation considerations pertaining to different configurations for spectral tuning. In addition, implications associated with extrapolation toward a full- scale flight instrument design will also be addressed.
