NASDI: Canadian Agroclimate Temperature Anomalies, 1991-2020 Normal

Difference from Normal Temperature values are computed by subtracting the 1991-2020 normal monthly average temperature from the average monthly temperature. The National Agroclimate Series of Derived Indicators (NASDI) from Agriculture and Agri-Food Canada provides real-time and historical agroclimatic variables for Canadian agricultural regions. Data is available in formats including PDF, GEOTIF, and ESRI REST.

Use Cases

• Modeling crop yield sensitivity based on monthly temperature anomalies described in the dataset.
• Tracking long-term warming or cooling trends in agricultural regions based on the difference from normal temperature indicator.
• Assessing climate risk for agricultural planning using the real-time and historical climate information incorporated in the NASDI products.

Strengths

• Uses a defined 1991-2020 baseline for calculating temperature anomalies.
• Incorporates both real-time and historical climate information for trend analysis.
• Covers Canada's diverse agricultural regions as stated in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to open_canada.
