Data Management
Similar to its mission operations
approach, TIMED employs a unique distributed data management system, where
spacecraft instrument teams will individually process data, generating
products for distribution, from their respective Payload Operations Centers.
This approach is unique compared to traditional space science missions
and to most remote-sensing programs.
Traditionally, space science
missions maintain one central data center, which has full control of the
data from downloading it from the spacecraft to processing, archiving
and distributing data products. This approach typically requires larger
staffs working around-the-clock shifts.
But within TIMED's distributed
data management system, the Mission
Data Center (part of the Mission Operations Center) is responsible
for downlinking raw data from the spacecraft and then sending it, via
direct links, to processors at each of the remote Payload Operations Centers.
These centers will process their instrument's raw data and turn it into
data products that can be used by the public, and scientific and educational
communities. Due to TIMED's more efficient data management system, the
Mission Data Center and remote data processing sites are operating with
smaller staffs working one 8-hour shift a day.
Once a remote site completes
a data product, a notice is sent to the Mission Data Center indicating
that the product is available for distribution. The Mission
Data Center maintains a central catalog of TIMED data products, which
incorporates query capabilities and a Web-based interface so the public,
science teams, and educational communities can quickly and easily retrieve
products from the remote sites via TIMED's Web site. A description of TIMED's distributed data management system is provided in its Project Data Management Plan.
