Database: submission, status, future

Send data and receive confirmation is not enough!!!! Remember to import or discard your variables!!

Status Looking to who submitted what…..

In the next weeks the Greengrass database will be incorporated in the Carboeurope IP database and processed. We asked also the data from Carbomont without answer We are waiting the data from the Siberian projects (from Eurasia-net to TCOS) We will try also to obtain data from the Amazonian project from EU Any other dataset is welcome We invite also the PIs to send their data and in particular the 2003 missed months!!! NO (only partially)… Still without (partially)… Coming

Questions/discussion about the status?

Gapfilling intercomparison results

From the Gapfilling WS: Do we need more variables? Flag indicating if there are footprint problems (particularly for crop) Flags indicating the management LAI or NDVI or Vegetation height (crop and grass) NOTE! It is not a good solution to put simply qcFc = 2 because the qcFc are defined from Spoleto!

The database role in standardization 1)Storage correction whit Sc provided by the PI (NEE_or) and calculated from the CO 2 concentration top of tower (NEE_st) 2) Ustar threshold calculated centrally 3) Spike filtering performed centrally 4) Gapfilling performed centrally using the two best methods from the gapfilling intercomparison 5) Partitioning in GPP and TER performed centrally BUT What about “standard quality flags obtained from the raw data”? What about the corrections/checks applied to the raw data? What about the corrections implemented in your software? Unfortunately not all the PIs are sending the correct quality flags. Many sites have all the data with qc=0, or with all qc=2. There are sites that are not applying the qc correctly and mix-up with ustar filtering or footprint How many of you provided these info correctly to the database? Are these information important?

Setting Comparison BA – 3D – ConstTLag LD – 3D – AutTLag BA LD

µmolCO 2 m -2 s -1 Generally this has a small effect to the sums However can have effect on the single half hour

How to solve this problem? How to avoid these differences? Using the same software with exactly the same settings BUT We compared different software and they give very similar results with the same settings Using the exactly the same settings BUT Can we define a “right” set of corrections and settings? What about the uniqueness of the sites? Use what you want but tell me what you did… BUT How can you send these information to the database? How many of you sent the information about the 2D 3D or PF correction applied? How many of you are sending the updated versions of the GEN file?

The best would be to have a common software where: -The user could decide which correction to apply -There would be implemented all the possible corrections -The user could also propose and add new options/corrections -All the settings used would be summarized in a table as metadata -The output would be directly formatted to be uploaded in the DB But to work, this software should be: -As flexible as possible -Available for all the HW/OS platforms -Continuously updated -User friendly for not expert users And in particular: -FREE -OPEN SOURCE -COMMON PROPERTY (CarboeuropeIP, Fluxnet)

Are you interested in developing a common “community owned eddy covariance software”? We started developing the structure of such a software and now it is ready for your input… code: FORTRAN 77/90 OPEN-SOURCE CODE SET-UP BASED ON “.ini”-files

ACQUISITION PROCESSING core: FORTRAN 77/90 Features a user-friendly GUI Simple but less flexible GUI: C (LabWindows) Graphical version available

FLUXNET Synthesis Workshop February 2007 – La Thuille - Italy Different networks involved: CarboeuropeIP, Ameriflux, Fluxnet-Canada, LBA, CarboAfrica, OzFlux, TCOS Siberia, ChinaFlux, KoFlux, AsiaFlux, NECC, US-China Carbon Consortium Sponsors (not all confirmed): GTOS ILEAPS NASA DAO Global Carbon Project CarboeuropeIP Organizing Commitee: D. Baldocchi T. Boden P. Ciais B. Cook B. Law D. Papale M. Reichstein S. Running R. Valentini

FLUXNET Synthesis Workshop 2007 The workshop has been designed as a real hands-on data synthesis workshop It will be restrict to people coming from the different regional networks Particularly scientists most interested in synthesis activities should participate This does not preclude valuable post-workshop intellectual input from non-participating scientists for the scientific papers and co-authorship The harmonized global dataset will be available to all the community for other synthesis works particularly for the many topics that will be not discussed at the WS Dataset will be pre-processed in an harmonized way before the WS February 2007 – La Thuille - Italy

FLUXNET Synthesis Workshop February 2007 – La Thuille - Italy Carboeurope-IP Ecosystem Component will participate to the synthesis All the datasets submitted to the CarboeuropeIP database will be included (only if with good quality) and the PIs will be part of the activity. If you don’t want that your data will be used in this activity please send us a note. Carboeurope will have 7-8 participants to the WS and we have to provide a list of about names with topic of interest to the Organising Committee before November 30th, with if possible a good balance between experienced and young PostDoc-level scientists Based on the suggestions of all networks and in consultation with networks, the Organising Commitee will propose a final participant list before December 10th (in order to avoid gaps or overloaded topics).
