Canada’s Polar Communications and Weather (PCW): Dual Objectives
• Reliable communications in the high latitudes (North of 70º) to ensure:
–Security
–Sustainable Development
–Support to Northern Communities
–Air and Marine Navigation
–Arctic Science
• Provide high temporal/spatial resolution meteorological data above 50º N in support of:
–Numerical Weather Prediction (short to medium range)
–Environmental monitoring, emergency response
–Climate monitoring
PCW to have an operational status linked to NRT meteorology Launch target: 2016
