In application: Climate Monitoring (GCOS)

Goal Breakthrough Threshold
Uncertainty 0.5 mm/h
Stability/decade (if applicable) 0.02 mm/h

Validated: 9/25/19 Source: GCOS-200: The Global Observing System for Climate: Implementation Needs (Published 2016)
Comment: Requirements in the GCOS-200 IP, Annex A, are only specified at the goal level. Requirements for observing cycle are monthly (resolving diurnal cycles and with statistics of three-hour values) Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
