4. 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

5. 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

6. 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

7. October 2, 2002National Climatic Data Center Continuous Monitoring of Surface Skin Temperature – Maximum and Minimum Nighttime minimums show heat island and urban/rural differences Diurnal range related to evapotranspiration and summer heat wave stress Frost area identification for targeted mosquito/west nile abatement Courtesy UAH/GHCC 7 Application:

8. October 2, 2002National Climatic Data Center Energy Application - Solar Insolation for Solar Power Solar insolation is reliably obtained from GOES New GOES Active Archive will allow access to recent, and eventually the entire, GOES archive GOES Scientific Stewardship will improve quality control, calibration, etc. 8 Application:
