1. NOAA’s Climate Data Record (CDR) Program Leveraging 3 Decades of Satellite Investments To Provide Trusted Climate Information to Society Jeffrey L. Privette CDR Program Manager NOAA’s National Climatic Data Center

2. NASA Develops New Observing Technology 2008 Earth Observing Constellation

3. NOAA Collects Multiple Decades of Data using Same or Similar Systems

5. Calibrated

6. netCDF

7. 8km, 3-hourly(Knapp et al., 2007) Different designs, spectral bands, formats, navigation, resolutions, algorithms (Knapp et al., 2007) New intensity estimates (e.g., Kossin et al. 2007)

8. CDR Development Requires Application of Best Methods Across Different/Dirty Data Epochs Uncorrected Data Time Series Contain Both EnvironmentalInformation and Satellite-induced Artifacts Operational weather and hazard products are produced rapidly to potentially save life and property New satellite launched Top of Atmosphere Vegetation Index Vegetation Greenness Index Top of Canopy Vegetation Index Climate Data Records (CDRs)provide long term product consistency through rigorous reprocessing with advanced algorithms, ancillary data and evolved instrument understanding.
