Objectif(s): To evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) for the monitoring of lake ice breakup and freeze-up.
Description du projet: This licence has been issued for the scientific research application No.4648. This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the form of oblique aerial photographs are required to assess the accuracy of the image processing approaches developed and the resulting lake ice on/off information products (maps). Two of the three study areas for the project are located in the Northwest Territories (nearby Inuvik and Yellowknife, respectively). The third area of interest is located in Ontario (Experimental Lakes Area). This research involves the acquisition of RADARSAT-2 images over selected lakes nearby Inuvik and Yellowknife, the conversion of these images to RCM-type images, the generation of lake ice on/off information products, and the validation of these products with the help of aerial photographs. The required aerial photography, both during the spring and fall period, will be contracted out to local organisations/businesses. The results of the project will be published in journals subscribed to by most libraries. Following publication of results, selected lake ice on/off information products will be made publicly available through GEOGRATIS or the CCRS website. When in Inuvik, the team will make an effort to be available to meet with or give a presentation to interested community members. A factsheet describing the overall nature of the project is available on the NRCan/CCRS website (http://www.nrcan.gc.ca/earth-sciences/permafrost-ice-snow/lake-river-ice/9164 ). The fieldwork for this study will be conducted from April 20, 2020 to June 30, 2020.
