3. PROJECT SUMMARY

4. Data and methods AVHRR record, ‘81 – ‘’99 MODIS record, ‘00 – ’13 ‘98-’02 SPOT- VGT Data to Bridge AVHRR & MODIS records Data retention filter. Only retain high quality data VIIRS ? Homogenous clusters map. Areas with same characteristics Continuity Transfer Function map 1981 -2013 sensor independent surface reflectance record MEASURES VIP ESDRs Science Review Panel

5. ESDR Products and objectives • Support the Earth Science research community by providing • Long term, multi-sensor, reliable, and consistent Earth System Data Records (ESDR) of • Sensor independent EVI (2-band version) , NDVI, and • A set of Remote Sensing based “Land Surface” Phenology parameters LSR 1981 .. .. .. 2013 Product Characterization Errors/Uncertainty in EVI/NDVI NDVI EVI Phenology metrics (season start, length, etc…) Errors/Uncertainty in Phenology metrics EVI/NDVI & Phenology ESDRs • These ESDRs are expected to be well characterized, of high consistency, and with known error, to support studying climate change & impacts on the Earth system. • First generation (Beta) product suite to be released late 2010 early 2011.http://measures.arizona.edu & Distribution Site: http://measuresvip.cr.usgs.gov/test/index.php#) MEASURES VIP ESDRs Science Review Panel

6. Science review panel MEASURES VIP ESDRs Science Review Panel

7. Project Review - FORMAT • A Day+ long meeting organized along the project’s goals and activities • Our team will present the following topics: • EVI2 Algorithm • Across Sensor Continuity Algorithm • Phenology Algorithm • ESDR product format, Error & Uncertainty, Distribution, User Support, and Long Term Archives • Potential Applications • The science review panel is expected to provide feedback and critique of: • The Science Algorithms • Product format, Specification, Characterization, and Error and Uncertainty Approach • Distribution and user support system • Application and user Community needs • Miscellaneous • Where to Improve MEASURES VIP ESDRs Science Review Panel

8. Science Review Panel - Participants • The review panel was selected based on expertise, project needs, and availability MEASURES VIP ESDRs Science Review Panel

9. Review – Goals & Expectations • The project team expects the following: • Critique and Feedback on our choices of algorithms/Plans/Approaches and long term goals • Where should we improve? We’re particularly encouraging and seeking feedback on: • Science Algorithms • Based on your own experiences, similar and previous efforts, and community expectations • Product specifications & characterization • This has been always a serious problem with RS data, hence we’re very open to feedback • Projection, contents, data format, parameter specification, etc… • Error and Uncertainty & How to convey product usefulness • This is a fairly new focus for RS measurements that should conjure lost of discussions • How to approach validation , what is validation, (data from 80ies) when and how a product is considered validated? • How this feeds back into the production/algorithms? • Concept of consistency versus un/certainty as opposed to absolute validation • How to measure success • etc… • Data formats, distribution mechanism, user support MEASURES VIP ESDRs Science Review Panel

10. Review – Follow up mechanism • We’re expecting the panel to provide us with a summary/document of their findings, suggestions, comments, and expectations. We assigned your names to a topic, and we can adjust these during the meeting: • The team will provide the panel with a plan on how to accommodate and implement the recommendation of the review • We will keep the panel informed on our progress and solicit further feedback (via the project web site) MEASURES VIP ESDRs Science Review Panel

11. Review – NASA Expectations • These are reworded expectations that were developed during discussions with the NASA project managers (Diane Wickland and Martha Maiden): • Algorithms and approaches must reflect community consensus • The project team is expected to strive to implement what the “majority” sees best • The ESDRs must reflect the community wishes so they get used efficiently • Balance between the desire of no distribution delays and potential early product issues, caveats, warning, etc… • When should the product be released • What metrics should we consider as indicators of project success • No room for research and validation • Needs to transition to a future steady state beyond the project life • How to extend time series (with new data) • How to continue supporting the product suite • Core production MEASURES VIP ESDRs Science Review Panel

12. Additional information

13. Total of three reviews • There are plans for 2 more rounds of reviews in addition to this one • ATBD review • Focus on science algorithms • UWG style review (April 2011) during the ORNL/LP-DAAC UWG Meeting • Focus on the products, distribution, users support MEASURES VIP ESDRs Science Review Panel
