NITEOWL Reserch Program ...... The goal of the proposed project is to develop and validate an instrument capable of providing data on spatial and temporal variations of ozone distributions during a polar winter. The instrument will be deployed on a parachute from a sounding rocket. The ultimate goal is to create within the Canadian space science community and Canadian industry a capability for construction and deployment of a microsatellite-based system for global ozone monitoring. Such a system would be an efficient low-cost national alternative to the presently contemplated systems (TOMS, SBUV, GOMOS), and would provide important and timely information about the ozone layer to both the Canadian public and the atmospheric science community. We propose to develop an imaging spectrograph to measure the vertical and horizontal distributions of ozone and nad nitrogen oxide NO2 and NO3 at altitudes of 10 - 50 km during an Arctic winter night. The instrument is deployed by parachute from a sounding rocket at apogee near 80 km. Ozone and No 2 , NO3 concentrations are determined from stellar occultation measurements by a tomographic technique. The launch site for the mission will be Churchill, Manitoba. 1.2 Mission Objectives Science Objectives: -Quantify the spatial and temporal variations of ozone (especialy in the low stratosphere region?) and its effects on the global ozone balance as required by existing theoretical models of global ozone trends. Despite of wealth of experimental data on ozone distribution currently there is no global altidute resolved measurements of ozone. TOMS is producing now outstanding maps of total tropospheric ozone but they are of low accuracy (of the order of 50 %) and rovide little details on altitude distributions. Currently existing models of ozone dynamics predict large vertical ( in 2-3 km) and horisontal (100-500 km) variations of ozone distributions. They also predict an importance of low amplitude (of the order of 10 %) variations of ozone concentrations in the low stratosphere. For further validation and contrain of theoretical and computational models for global ozone trends it is imperative to posses an experimental data with horizontal resolution ~ 100 's km and vertical resolution of 2-3 km with overal precison less than 10 %. ?Elucidate the role of "nighttime species" No2 and NO3 in the global ozone dynamics National Space Science and Technology Objectives: -Maximize training potential for students and young researchers by providing them wide opportunities for project development in the environment of a multidisciplinary team comprising academic and industrial partners -Develop in Canadian industrial sector a potential to create and manufacture a relatively low-cost microsatellite-based system for high-resolution global ozone monitoring, drawing upon the national capabilities International Collaboration Objectives: -Maintain and increase Canadian involment in the international efforts to understand and predict global ozone trends via providing it with high quality data on spatial ozone distributions Public Service and Educational Outreach Objectives: -Increase public awareness of space science missions via communicating issues involved in ozone depletion This project will further the Canadian contribution to the study of internationally relevant research and is sure to be of benefit to all interested parties, including Canadian technological industries, academia, government agencies and the business community. The benefits are further compounded by both increasing the global exposure of the Canadian Space Agency while maintaining Canadian ownership of the knowledge acquired with most of the money remaining in this country. --------------6F307C3670D8--
