  7. Post-Field Data Quality Control(Propose) • Quality Assurance and Quality Control • Specification of user requirements • Specification of the measuring system • Identification of suitable measuring locations • Definition of necessary calibrations • Definition of quality control (QC) – Quality Evaluation • Corrective actions – short time answer • Feedback from the user of the data (intranet / Internet) (Foken et al 2004) • LBA Researcher • LBA Students • Other researchers • Other Students • Governmental Institutions • Consortiums (CEOP, Fluxnet etc)

  8. Post-Field Data Quality Control(Propose) Pre-analisys Protocol First Step In test (Semi-automatic) Automatic collection and transmission

  9. Post-Field Data Quality Control(Propose) Pre-Analisys Protocol Second Step In test (Semi-automatic) (Reichstein et al 2006) http://www.bgc-jena.mpg.de/bgc-mdi/html/eddyproc/index.html Send to user

  10. Post-Field Data Quality Control(Propose) Pre-analisys Protocol Second Step planning (automatic – intelligent Neural Net and algorithm) Automatic collection and transmission

  11. Post-Field Data Quality Control(Propose) Pre-analisys Protocol Third Step In test (semi and automatic) Reports to user

  12. Post-Field Data Quality Control(Propose) Recommendations • Strong metadata policy • Increase and create more Micrometeoroly Instrumentation Labs • Adopt a minimal standard Post-field data quality control protocol • Net data transfer (reduce the problems time detection) • Contract more MsC and PhD - local Team • Support to a reserve equipments and replacement kits program • Create a data base to improve and optimize this program
