| dc.description.abstract | The development of remote sensing satellite-borne instrumentation for the study of the Earth’s atmosphere has provided an immense increase in our understanding of atmospheric trends and processes. The Canadian built OSIRIS satellite instrument uses the limb scatter technique to measure scattered sunlight for the retrieval of vertical profiles of atmospheric species such as ozone. Recently, the next generation instrument, CATS, based on the OSIRIS design, is under development to continue OSIRIS measurements into the future. One key optical design change for CATS is the ability to measure simultaneously over multiple fields of view. However, this new optical design concept needs to be tested and evaluated. To achieve this, a prototype slit plate was installed into the preflight developmental version of OSIRIS, called OSIRIS-DM, for testing in the laboratory and on a stratospheric balloon. In this thesis work, an evaluation of the performance of this multi-slit instrument was undertaken through laboratory calibrations and limb scatter measurement collection. The calibration process includes a wavelength registration, a spectral point spread function analysis, a relative calibration and an absolute calibration, all performed with laboratory equipment. Along with laboratory calibrations, this thesis work involved preparation for the stratospheric balloon mission including the development of a flight ready electronic control and communication system to operate OSIRIS-DM during the mission. The upgraded instrument was launched on September 19, 2014, and ascended to a stable float altitude of 36.5 km. The collected flight measurements were used to evaluate the calibrations and general instrument performance. Overall, the laboratory calibrations proved to be sufficiently accurate and the measurement collection produced multiple spectra that may be used for atmospheric analysis in the future. These results show that the multi-slit design of the slit plate produces an instrument that can be reliably calibrated and implemented for limb scatter measurement collection. | en_US |
