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

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 NDVI EVI Phenology metrics (season start, length, etc…) 1981.. 2013 Errors/Uncertainty in EVI/NDVI Errors/Uncertainty in Phenology metrics Product Characterization 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#) http://measures.arizona.eduhttp://measuresvip.cr.usgs.gov/test/index.php# MEASURES VIP ESDRs Science Review Panel -5-

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 -7-

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

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 -9-

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 -10-

11. 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 Review – NASA Expectations MEASURES VIP ESDRs Science Review Panel -11-

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 -13-
