OSCAR - Observing Systems Capability Analysis and Review tool
OSCAR is WMO's global repository of surface and space observing system capabilities.
OSCAR is a web-based tool in which metadata is registered, managed and archived. It records observing system requirements and allows critical reviews of how well actual capabilities address requirements.
It allows users to better understand their data. Knowing where, how and why observations are made helps with better planning of network evolution, and shows how networks change over time.
