NASA, together with its Brazilian scientific counterparts INPE and INPA, selected investigators who planned to deploy U.S. aircraft and instruments to Brazil to meet important observational needs of the ongoing program of research in NASA's component of LBA. Together with in situ field observations, and complementing observations from the space-based systems, this campaign had hoped to play a critical role in research to "scale up" scientific understanding of terrestrial ecology and land cover change in the Amazon, and to reduce uncertainties in the understanding of regional and global carbon balance and trace gas fluxes.
- reduce uncertainties in the understanding of regional and global carbon balance and trace gas fluxes
- provide essential information for evaluating approaches to quantify vegetation recovery and biomass change following forest clearing and various forms of land use
- enable more accurate biophysical parameter assessments over the region
- enable validation of satellite algorithms for such assessments from space across Amazônia
These proposed investigations were first reviewed and selected by NASA and Brazil’s Ministry of Science and Technology (MCT). Then they were scientifically reviewed and recommended for consideration by the LBA Scientific Steering Committee, and were pending approval of the Brazilian government. Approval was not received within the time available to provide support for the field activities.
