Recent work in Canada for the proposed Chemical and Aerosol Sounding Satellite (CASS) mission
Abstract
The Chemical and Aerosol Sounding Satellite (CASS) mission is a proposed CSA-NASA collaboration to address the Committee on Earth Observation Satellites (CEOS) recommendation for continuity in climate-quality profile measurements of stratospheric and upper tropospheric composition. The mission would include two instruments: an infrared Fourier transform spectrometer (ACE-FTS-II) and a UV/VIS spectrometer (SAGE III). The two CASS sensors would focus primarily on trace gas and aerosol measurements using the solar occultation technique. These global measurements are aimed at understanding the changes that are occurring in our atmosphere including recovery of the stratospheric ozone layer, changes in climate due to increasing greenhouse gases and increasing pollution in the troposphere. Over the past year, two studies have been funded by the Canadian Space Agency (CSA) to examine the development of the ACE-FTS-II instrument and to investigate the accommodation of the CASS instruments on different platforms. In parallel, a small Canadian mission definition team has been established to work on the science objectives and mission requirements within the Canadian context. This presentation will describe the results of these two CSA-funded studies and the progress that has been made by the Canadian definition team.
