  4. GCOS Satellite Climate Monitoring Principles 1 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 6 2 7 3 4 8 5 9 10 4

  5. NOAA Scientific Data Stewardship New approach for real time management of climate data 6 7 Network Performance Monitoring Climate Data Records 10 Observations & Metadata GCOS principles Archives Reprocessing and Reanalyses Analyses and QC Climate Quality Products Feedbacks Climate Analyses Stewardship Teams • Benefits • Rapid feedback to observing system • Data prepared for prediction and analysis • Model-data synthesis on operational basis • Simple straight forward data access • 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 5

  6. 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 5 4 GCOS principles 6

  7. Application: 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

  8. Application: 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
