Transcript CSA - Polar Communications and Weather Mission
Polar Communications & Weather (PCW) Mission
Aurora Borealis
Dual Objectives: Communications & Weather
• Reliable communications in the high latitudes (North of 70º) to ensure: – Security – Sustainable Development – Support to Northern Communities – Air and Marine Navigation • Provide high temporal/spatial resolution meteorological data above 50º N in support of: – Numerical Weather Prediction – Environmental monitoring, emergency response – Climate monitoring
Mission Requirements
• To provide continuous meteorological service and information for the entire circumpolar region, with the imagery data “refreshed” as frequently as practical. GOAL 15 min • To improve weather prediction accuracy and timeliness by providing high quality data currently not available or available with insufficient spatial / temporal resolution • To improve the monitoring and prediction of air quality variables • To improve the modeling of physical processes in the Arctic environment • To develop measures of climate change through high quality monitoring of key atmospheric and surface variables • To improve observation and forecasting of space weather • To have a
proto-operational
system in place by 2014.
