Long-term Observations are Needed for Climate Monitoring

99

As we look back in time from 2100, what will be the analog for climate monitoring?

• anomaly correlation of seasonal forecasts?

• ?

• ?

• ?

• Continuity and improvement of operational constellations

• Sustained observation of all ECVs observable from space

• Transition Research to Operations for priority, mature observations

• Generation of QC products

• Integration : network optimization, system interoperabilitycomposite products
