Description
1991-2020 long-term average precipitation data for Canada, with derived weekly indicators showing accumulated precipitation differences from the norm. The National Agroclimate Series of Derived Indicators (NASDI) is produced by Agriculture and Agri-Food Canada, providing both real-time and historical climate information. It covers multiple accumulation periods including 1, 2, 3, 6, 9, 12, 18, and 24 months.
Use Cases
Modeling drought risk and agricultural water stress based on precipitation deficits.
Analyzing long-term climate trends and anomalies across Canada's diverse agricultural regions.
Calibrating hydrological models using standardized precipitation difference indicators.
Supporting policy and resource planning for agriculture with real-time and historical agroclimatic data.
Strengths
Long-term average baseline is clearly defined as 1991-2020.
Covers eight distinct accumulation timeframes (1 to 24 months) for flexible analysis.
Data is regularly updated and incorporates both real-time and historical information.
Produced by the authoritative national agency Agriculture and Agri-Food Canada.
Limitations
