    NOAA's Climate Data Record (CDR) Program NOAA's Climate Data Record (CDR) Program Presentation Transcript

    • 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
    • NASA Develops New Observing Technology
      2008 Earth Observing Constellation
    • NOAA Collects Multiple Decades of Data using Same or Similar Systems
    • Revealing Climate Information Within Archived Data
      RawSatellite
      Data
      30 Year FundamentalCDRs
      Global and Basin Objective Hurricane Intensity Trends
      29 GeostationarySatellites + 8 Polar Satellites
      HURSAT-B1
      • Geo-located
      • Calibrated
      • netCDF
      • 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)
    • 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.
