Adapting the NSCAT data system to changing requirements

NSCAT is a spaceborne, eight-beam scatterometer which measures ocean backscatter. A description is given of its non-real-time ground-based science data processing system, particularly the changes to the baseline design in response to changes in requirements. The new requirements are in five areas: (1) telemetry data source, (2) data catalog, (3) hosting instrument operations, (4) definition of data granularity (revolutions) and (5) science team data needs. The science team requirements consist of a need for new or revised products, different delivery volume and schedule, and electronic communication among team and with the project.<
