Policy Implications

🌾 Agricultural Insurance

21.2% of active stations failing means actuarial models for AgriInsurance lack the precipitation data they need. This directly affects crop insurance pricing for farmers across ALBERTA, BRITISH COLUMBIA, ONTARIO, QUEBEC.

🌡️ Paris Agreement (Art. 13)

Canada committed to transparent, accurate climate monitoring. With 228 active stations failing to transmit data, the precipitation record has permanent gaps that undermine international reporting obligations.

🔬 Scientific Integrity

Climate research requires continuous long-term records. Stations classified as ACTIVE_TRANSMISSION_ISSUE create gaps that distort trend analysis and regime change detection.
