October 2, 2002National Climatic Data Center GCOS Satellite Climate Monitoring Principles Minimize orbit drift Ensure sufficient overlap Replace prior to failure Rigorous pre-launch calibration Adequate on-board calibration Operational production of priority climate products Facilitate access to products, metadata, and raw data Continue baseline instrument observations on decommissioned satellites Need in situ baseline observations Real-time monitoring of network performance 4

October 2, 2002National Climatic Data Center New approach for real time management of climate data Observations & Metadata Climate Quality Products Stewardship Teams Analyses and QC Feedbacks Reprocessing and Reanalyses Archives Benefits Rapid feedback to observing system Data prepared for prediction and analysis Model-data synthesis on operational basis Simple straight forward data access NOAA Scientific Data Stewardship Network Performance MonitoringClimate Data Records End-to-end accountability of data —Spatial and temporal sampling —Time dependent biases —Metadata —Reprocessing for CDRs Enable and facilitate future research Safeguard interests of future generations Climate Analyses 5 GCOS principles

October 2, 2002National Climatic Data Center Improved Pre-Launch and In Orbit Calibration of GOES Is Essential Precise matches with in situ sea surface temperature show bias in diurnal cycle – largely due to GOES calibration This is partially caused by ‘midnight effect’ due to solar heating of instruments (esp. in 12 micron window) Problem larger than originally thought 6 GCOS principles
