Climate Synthesis & Future Directions

This article explores the accuracy and limitations of trends in key climate variables observed through satellite data. It also investigates the role of aerosols on climate and changes in oceanic precipitation over the 20th century. The challenges of improving calibration and validation, extending satellite data records, and using satellite products for climate projections are discussed.

  1. ClimateSynthesis & Future Directions

  2. STAR Science Foci Can we assess and understand changes in key climate variables from long-term records of satellite observations? What are the accuracy and limitations of trends. What is the quantitative role of aerosols on climate ? How much has oceanic precipitation changed over the 20th century? Can the observational sea level rise budget be closed? 2

  3. STAR Challenges • Increasing confidence in accuracy by improving calibration and maintaining in situ validation sites • Developing advanced techniques to estimate trend, confidence, and number of years needed for trend detection • Extending historical and current satellite climate data records with future satellites and integration with other observing systems • Improving climate projections and reanalyses by using satellite products as input, as well as for validation NCEP upper tropospheric water 20% higher than ECMWF, Which is right? ECMWF computed radiances in water vapor band is 1.5 K closer agreement with AIRS than NCEP 15% change in water vapor Results in signal of ~ 1.25 K AIRS sensitivity to changes in geophysical parameters 3

  4. NOAA new climate services is proceeding with Operational Climate Data Records Program STAR contributes to R&D and pre-operational products STAR leading role Management BoardCCSP Observations Management Structure Intl Data Programs Product Development Teams (CDRs, CIRs and Support) Experts in Instrument Characterization, Algorithms, Validation, Data Management, Applications, and Observing System Performance Monitoring Improved CDR and CIRs Leveraging Resources / Collaboration Observing System Performance Monitoring Production of Near Real-time CDRs Processing of CDRs for Long-term Records Climate Information Records Other Agencies GEOSS, CEOS Design for Future Systems CDR Stewardship Engaging User Community Modeling Monitoring Prediction Research 4

  5. International Framework STAR Leads National Climate Data Center (NCDC) Leads • Address the requirements of GCOS in a cost-effective, coordinated manner, capitalising upon the existing expertise and infrastructures. • Continuous and sustained provision of high-quality Essential Climate Variables • GSICS enables the generation of Fundamental Climate Data records and provides the basis for sustained climate monitoring and the generation of ECV satellite products. 5

  6. STAR Integration Efforts Community consensus Climate Data Records with NCDC Leading GSICS Leading several CDR teams (e.g. MSU/AMSU & Ozone) Leading Committee on Earth Observation Satellites (CEOS) response to address international collaboration on the generation of essential climate variables 6

  7. STAR Research to Operations & Sustained Applications Providing routine accessible updated Climate Data Records Providing datasets for use in IPCC assessments Providing near real-time critical datasets for NOAA operational drought monitoring Providing routine sea-level monitoring information from Jason series. 7

  8. Future Direction Improve quality and error budget of climate data records Extend historical records with future sensors Blend different datasets to improve temporal representation and accuracy Develop Climate Information Records Next-steps threads Enhancing instrument characterization and intercalibration for current & new sensors Community engagement 8
