Observation continuity planning
The missions supplying essential climate and hazard observations are mapped with their expected lifetimes and successors, so gaps in records can be anticipated.

用于风险情报和可持续发展的空间 系统 and satellite services provide the observation, communication and positioning that hazard monitoring and warning depend on. In this field the concern is continuity and access: which missions supply which observations, how long they last, and what happens if one fails.
用于风险情报和可持续发展的空间 系统 and satellite services provide positioning, timing, communication and observation from orbit. Many terrestrial systems depend on them, making their disruption a cross-sector risk. In climate and hazards and disaster and crisis, space systems analysis reveals dependencies of finance, power grids and transport on satellite timing and navigation. It supports planning for backups and space weather events. The canonical description is on STEM Commons.
The missions supplying essential climate and hazard observations are mapped with their expected lifetimes and successors, so gaps in records can be anticipated.
Satellite links that carry observations and warnings to remote areas are documented as dependencies of the warning chain.
The process by which space agencies provide imagery after major disasters is described, including how authorised users request it.

系统 are tested on the ground before launch and monitored in orbit. Conjunction assessments and service performance are checked against independent tracking.
| 核查 | 如何开展 |
|---|---|
| Mission status verification | Mission status is confirmed against agency records, not secondary reports |
| Single-mission dependency | Observations relying on one mission are flagged |
| Data latency | Time from acquisition to availability is recorded for warning-critical products |
Debris growth, solar storms and interference are hard to forecast precisely. Ground segments and launch capacity are concentrated.
Assembled from the Nexus Standards area profile 气候风险标准: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

流程
Processing levels are mission specific; Sentinel-2 runs from Level-0 raw data to Level-2A, and CEOS Analysis Ready Data sets the minimum for analysis.
Neutral outline of a published external standard or method, from its issuing body. Not a record of operation. Nexus does not perform, certify or approve any step shown. A gate or decision belongs to the party the source names. Level-1B and Level-1C add corrections; Level-2A adds atmospheric correction and scene classification.
