Data Issues and Approach During Phase 2 of LBA Jim Shuttleworth University of Arizona The SAHRA Center

Constraining the Problem • Define a specific “End Date” for Phase 1 of LBA (in Fall, 2005?) because otherwise: • the LBA dataset is a “moving target’ • “milestones” dates for data submission can’t be defined • Survey all past and current LBA participants to define the dataset that will be available at specified dates, e.g. • December 31, 2005; • June 30, 2006; • Etc • Provide incentives and opportunities to encourage data timely data submission, in the form of • shared participation in “reporting & analysis” papers • teambuilding around “synthesis and interpretation” papers
Two Types of LBA “Value Added” Products • Multi-Observer Reporting and Analysis Studies • Document experimental sites and procedures • Document the similarities and differences between results at different LBA field sites • Investigate and document the relative strengths and weaknesses of datasets • Seek to address landscape-scale questions, and the site independence of answers to these questions • Multi-Participant Synthesis and Interpretation Studies • Seek to answer large-scale questions that require multi-site data • Will generally involve some type of “model” as a means of interpolating/extrapolating in space and time, e.g. • a data model (e.g. use RS data to interpolate/extrapolate site data) • a biophysical model (use site data to calibrate model parameters)
Multi-site Data Group 1 Group “M” Multi-Observer Analysis & Reporting Multi-Observer Analysis & Reporting Multi-Participant Synthesis & Interpretation Multi-Participant Synthesis & Interpretation Implementing the Opportunity • Define “groups” of multi-site datasets for multi-observer “analysis and reporting” studies • Define who will lead and who will represent each observer group in multi-observer “reporting and analysis” studies and papers • Set deadlines for submission of quality control data and text describing sites and methods (field methods, quality control,…) • Define the common analysis that will be undertaken for each contributed dataset • DO IT and WRITE ABOUT IT! MULTI-OBSERVER “REPORTING & ANALYSIS” OPPORTUNITIES
Possible Multi-Observer “Reporting and Analysis” Studies? • Documentation of LBA tower site array, and multi-site comparison of near surface atmospheric variables and surface exchanges at tower sites • Documentation of LBA multi-site “tree growth” sites and compare results • Documentation of LBA multi-site biogeochemical sampling and compare results • Several others(to be define in discussion at this Belem BA-SSC meeting?)
Multi-site Data Group 1 Group “M” Multi-Observer Analysis & Reporting Multi-Observer Analysis & Reporting Multi-Participant Synthesis & Interpretation Multi-Participant Synthesis & Interpretation Implementing the Opportunity MULTI-PARTICIPANT “SYNTHESIS AND INTERPRETATION” OPPORTUNITIES • Specify large-scale questions that require multi-site data that will be addressed • Define who will lead and who will participate in each synthesis group (Note: the peer review process for NASA AO may help do this) • Identify which multi-site data are required and when (in addition to that being made available for reporting and analysis studies described earlier) • Define the common synthesis and/or modeling procedures that will be undertaken to answer the question • DO IT and WRITE ABOUT IT!
Possible Multi-Participant “Synthesis & Interpretation” Studies • Around question/s relating to: • Amazonian Carbon Dynamics • Sustainability in Amazonian • Whole system functioning of Amazonia • Hydrometeorology of Amazonia • Future trajectories of change in Amazonia • Others? (to be define in discussion at this Belem BA-SSC meeting?)
Publication Venues and Dates? • Special Issues in: • JGR (Biosciences)? • IGBP (Springer) “Synthesis” Books? • Editorship and Titles? • LBA: Climate and Chemistry (Nobre, Assuncao, Andreae, Artaxo, Avissar,..?) • LBA: Land Use, Carbon and Biogeochemistry (Keller, Bustamante, Rocha, Viera, Malhi,..?) • Dates for submission? • May 2006, November 2006?
SUMMARY OF SUGGESTIONS • Define a specific “end date” for Phase 1 of LBA (Dec. 31, 2005?) • Define two types of activity to give the “value added” products • from LBA’s multi-site data: • Multi-Observer Reporting and Analysis Studies • Multi-Participant Synthesis and Interpretation Studies and identify specific opportunities in these two categories now • Specify who will lead and who will participate in each of these • tasks/opportunities, and what data are required • Define publication venues, submission dates, editors • Define a series of target dates at 6-month intervals (e.g. Dec • 2005, June 2006, December 2006,..) and survey all relevant past • and current LBA participants to define the dates that the data • required for each selected task will be available, using selected • co-authorship as the incentive.
