Research activities of interest, in priority order are:
1) Synthesis and integration of the results of LBA to answer one or more of LBA's research questions. Synthesis and integration of both data sets and scientific understanding are desired. Studies are expected to be focused on regional (>10,000 km2) or larger spatial scales and make effective use of remote sensing data.
Topics to be addressed, in rough priority order, are:
- Amazonian carbon dynamics. In particular, research is needed to quantify carbon sources and sinks in the Amazon and to reduce errors and uncertainties. Contributions to an LBA-wide synthesis documenting the dynamic carbon budget of the Amazon are desired.
- Sustainability in Amazônia. Research is desired that integrates what has been learned in LBA concerning nutrient dynamics, types of land use, land management practices, and the effects of climate change and variability in order to address the prospects for the sustainability of land use and ecosystem goods and services.
- Whole system functioning. Studies that address the interactions among Amazônia's ecological, biogeochemical, hydrological, atmospheric, and climatic components are solicited. These studies should integrate what has been learned throughout LBA. It is expected that LBA-ECO data and understanding will contribute to these analyses.
- Hydrometeorology. Studies are desired that link the land surface hydrology of Amazônia with mesoscale circulation patterns and investigate how both could be better understood using remotely sensed data.
- Future trajectories of change in the Amazon. Modeling studies that utilize LBA results to make projections of future Amazonian state and functions are of strong interest. Such studies must take great care to explain underlying assumptions, document uncertainties, and cover a range of plausible scenarios of change.
2) Research to complete the preparation and analysis of LBA-ECO data sets. The field phase of LBA-ECO is planned to extend into 2005, and it is likely that the processing and analysis of some data sets will not be completed before it ends. Successor proposals that undertake to complete the preparation and analysis of these data will be considered. New proposals to create new data products from existing LBA-ECO data sets, and possibly other LBA data sets or data from other South American sources, are also of interest. Such studies must explain the importance of the new data product, its relevance to NASA, and how it will be used to answer an LBA research question.
3) Research to place LBA research results in a global context. Studies that apply the new knowledge obtained through LBA to improve our understanding of the entire Earth system are desired. It is expected that LBA-ECO data and scientific results will be utilized in these studies but other LBA data and results also will apply. Use of remote sensing data is required.
