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
