How to find LBA data:

LBA Data and Information System (LBA-DIS)

A data and information management system located at INPE/CPTEC - the LBA Data and Information System (LBA-DIS) - has been developed by INPE, with NASA's participation.  The LBA-DIS holds, manages, and distributes LBA data and information. INPE is the repository for all LBA-DIS data and information, and NASA will have at its disposal copies of the system and of the data and information.  The core of LBA-DIS is the archival and distribution system at INPE/CPTEC, and managed by the LBA Central Office, which has full responsibility for LBA data archival and distribution for decades to come. This LBA-DIS central node has mirror sites and supporting nodes in the U.S. and Europe.  LBA-DIS activities, including those at other nodes are coordinated by the LBA-DIS Working group led by Mr. Luiz Horta, the LBA-DIS Officer. 

As required by Brazilian law, the original data collected in Brazil must remain in Brazil (copies may be retained by foreign investigators).   Additionally, NASA has agreed to ensure that copies of scientific data and results from LBA-ECO will be provided to INPE/CPTEC.  Deliveries of data and results to INPE/CPTEC to fulfill this NASA obligation should be detailed in the Data Plan section of LBA-ECO proposals.

The NASA-designated long-term archive for ecological and biogeochemical data from field campaigns is the Distributed Active Archive Center (DAAC) at the Oak Ridge National Laboratory (ORNL).  Thus, data collected through LBA-ECO will be archived and distributed at the ORNL DAAC as well as in Brazil.

An Internet-based approach for data and information management has been created for sharing scientific data within LBA. This aspect of LBA-DIS is distributed, consisting of LBA investigator websites, LBA project and module websites, the data archives at INPE/CPTEC and at the ORNL DAAC, and the Beija-flor system.  The data sharing approach involves two major data and information management tools:  Beija-flor and the LBA Metadata Editor (LME).  By using World Wide Web, or simply "Web" technology, the combined capabilities of Beija-flor and the LME allow data and documentation to be stored on, and accessed from, the networked computers of individual scientists located around the world. In the case of large data sets, data need not be immediately available through web access to be part of the LBA-DIS.  However, metadata must be present, and access should be provided through other mechanisms.

Currently, the LME facilitates the entry, editing, and storage of metadata in standard formats for use by Beija-flor.  Metadata is the information that describes the characteristics (e.g., geographic locations, parameter names, dates) of the various data sets.  Data set documentation capabilities are integrated with the LME.  Beija-flor provides the needed metadata search and sharing functionality by harvesting and organizing metadata that are then accessed and reviewed by the users.  Data providers and scientists use the LME to provide metadata to Beija-flor by saving the files of information in specified locations on their own or other web-accessible computer systems and marking the file as "searchable."  During its regular harvesting cycle (currently nightly), Beija-flor collects metadata from only the files that are marked as searchable.  Each Beija-flor system node (currently ORNL and the INPE/CPTEC) harvests metadata and builds a database of the harvested information.  Harvested information is shared across the nodes so that users are able to search and review available metadata by accessing the web-based Beija-flor and LME interfaces at any of the nodes with their web-browser software.
