Agroclimatic Zones for Norway Based on Crop Models and Subsidy Data

Norway's agricultural land is classified into agroclimatic zones using crop models and subsidy claim data. The dataset addresses previous methodological weaknesses by incorporating the latest standard climate normal, downscaled weather data to 250-meter hexagons, and phenological models for wheat, barley, and forage grass. It was created by researchers including Dorothée Kolberg and Eva S. F. Heggem, with data derived from a PostgreSQL/PostGIS table.

Use Cases

• National agricultural policy analysis based on updated agroclimatic zone classifications.
• Crop suitability and yield modeling for wheat, barley, and forage grass based on calibrated phenological models.
• Spatial analysis of agricultural resources at a 250-meter hexagon resolution based on downscaled weather data.
• Validation and improvement of agricultural subsidy programs based on integrated subsidy claim data.

Strengths

• Methodological updates include the use of the latest standard climate normal and an expanded set of weather data variables.
• Weather data is downscaled to a high-resolution 250-meter hexagon grid, incorporating vertical temperature gradients.
• Crop models for wheat, barley, and forage grass are calibrated with real-world data from research stations and subsidy claims.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale projects.
• The description mentions methodological limitations discussed in the source paper, but specifics are not provided here.
