  1. Contribution of LBA to the GHP And CEOP J. A. Marengo CPTEC/INPE. São Paulo, Brazil

  2. LBA-Large Scale Biosphere Atmosphere Experiment in the Amazon Basin LBA is an international research effort led by Brazil, and its main objective is to understand the functioning of the Amazon Basin in terms of its climate, hydrology, ecology, biogeochemistry, as well as on the impacts of land use changes on this functioning and on the interactions between Amazonia and the biogeophysical systems of the Earth. LBA Components PHYSICAL CLIMATE SYSTEM ATMOSPHERIC CHEMISTRY CARBON STORAGE AND EXCHANGE BIOGEOCHEMISTRY SURFACE HYDROLOGY AND WATER CHEMISTRY LAND USE AND LAND COVER CHANGE HUMAN DIMENSIONS

  3. GHP FOCUS As a key part of GEWEX,GHPinitiatives to demonstrate improved skill in predicting changes in soil moisture and related hydrological variables associated with water resources on time scales up to seasonal and annual as an integral part of the climate system. GHP SCIENCE ISSUES How do water and energy processes operate over different land areas? What is the relative influence of local and non-local controls on precipitation? What feedback mechanisms affect the water cycle and how do theseinfluence wet and dry periods? GHP STRATEGY ... Determine the climatic characteristics of (a) the CSE regions and (b) other land areas Close the hydrological budget over the CSE regions, show improvement in predictive capability, and identify key scientific issues for further improvement Carry out appropriate process studies over other climatic regimes to show closure and predictive capability

  4. OUTSTANDING TASKS These include: Develop and validate coupled atmosphere-surface-hydrology models Relate hydrological variables to water resource issues Identify surface, sub-surface and atmospheric scientific issues that are limiting our predictive capability Develop a strategy for advancing our understanding from regions to the global scale through the use of models, observational datasets and specific studies GHP COMPONENTS CSEs and ‘Associate CSEs’, ISLSCP, GRDC, GPCC GHP Cross-cutting efforts WESP Water and Energy Simulation and Prediction WRAP Water Resources Applications Panel DMWG Data Management Working Group CEOP Coordinated Enhanced Observing Period

  8. ERA-40 Amazon Basin Annual Water budget [AKB] Comparison of ERA-40 with Marengo et al. (2004) data (in green) Precipitation and runoff of right order, but correlation with data poor

  10. Current situation: 1.Manaus K 34 site (flux tower): Operational, data for EOP-3 is ready to be send to JOSS. Manaus pilot instrumented basin is not part of the “reference site” status. 2-Rondonia pasture site (operational), and data from EOP-3 is ready to be send to JOSS. Reserva Jaru (forest site) is no longer operational (?). 3-Santarem (operational), and data for the EOP-3 is being verified 4-Caxiuana (operational), and data for the EOP-3 is being verified 5-Pantanal (no longer operational?), no data from April-September 2003. 6-Brasilia (no longer operational?) LBA reference sites are funded by projects and grants from national and international sources, and they have a life span that depends on the duration of the projects. The sites do not depend on the National Meteorological Services. LBA and CEOP data policy: Acknowledgements or co-authorships (collaborations) are encouraged.

  12. Hydrologic data set collection • Objectives: • To serve as validation sites for the land surface parameterizations in coupled land-atmosphere-ocean models, essentially at a point or small area scale; • To serve as “tie points” or ground truth reference sites for remote sensing products
