In-flight Assessment of the Performance of a  Spatial Heterodyne Spectrometer for the Measurement of Upper Atmospheric  Temperature — PI: Dr. Gordon  Greeley Shepherd. There is an ever-increasing need for atmospheric  measurements of greater spectral and spatial resolution as well as improved  global coverage in order to better understand atmospheric processes in the  context of climate change. Spatial Heterodyne Spectroscopy ( SHS ), a space  technology that recently emerged, has the potential to meet this need. This project aims to support Canadian  participation in the assessment of the performance against the design  parameters of an SHS for the measurement of atmospheric temperature from  airglow, which will be launched on a satellite in the near future. It will  build on solid Canadian expertise and skills in the use of this new capability  in the future.
