| Abstract | Canada's RADARSAT Constellation Mission (RCM) will have the capacity to acquire C-band compact polarimetry (CP) data in all imaging modes, over swaths up to 500 km wide. Our study aimed to assess and
develop the utility of RCM CP data for the purpose of lake ice breakup monitoring. The breaking ice and open water information content of R2 polarimetric data and simulated RCM CP data was compared. Despite relative losses in terms of polarization
diversity and radiometric sensitivity, RCM CP data were concluded to make a good source of information in support lake ice breakup monitoring. For that reason, a CP-based approach, named CP LakeIceBC, to classify breaking ice and open water for the
purpose of lake ice breakup monitoring was developed. CP LakeIceBC is driven by incidence angle information, uses five CP backscatter variables (RH, RR, RV/RH, RR/RL, and conformity), and is compatible with high and medium resolution RCM CP products.
Application of CP LakeIceBC to representative simulated products yielded classification accuracies ranging from 73.2% to 99.1% and 60.8% to 99.5% for breaking ice and open water, respectively. |
| Summary | (Plain Language Summary, not published)
The Radarsat Constellation Mission (RCM) represents a significant investment for the Government of Canada and lake ice is an important component of
Canadian landscape. The timing of lake ice breakup influences natural, cultural and economic systems and is of operational interest to Environment Canada and Parks Canada Agency. This paper prepares users in and outside government for using RCM
compact polarimetry (CP) images in lake ice breakup monitoring. Radar satellites are an effective tool for this because the area of interest is vast, remote and often affected by poor weather and daylight conditions. CP is a new capacity that
promotes more effective use of radar images in the management of Canada's natural resources and lands. |
