Technical Description

The Extreme Cold Monthly Summary product provides valuable insights into the frequency of extreme cold actuals across the globe at a monthly timescale. This product seeks to identify areas where cold conditions may cause potential damage to life and property.

The product's severe_cold_frequency field is a human-centered metric built as a critical indicator of when it becomes too cold for humans to safely endure outdoor activities. It offers a straightforward and comparable measure across diverse locations, making it a valuable tool for identifying areas with consistently low temperatures that may pose risks to human health.

The product's cold_anomaly_frequency field detects locations experiencing moderately low temperatures that are concurrently below the normal conditions for that area. It considers regional acclimatization and ensures an absolute baseline for classifying extreme cold events.

Together, these indices contribute to a comprehensive evaluation of extreme cold events, considering both absolute thresholds for human safety and anomalies in temperature patterns relative to regional norms.

This dataset contains the following fields:

  • severe_cold_frequency: Rate of days/month (between 0-1) with a mean wind chill at or below the 'High Risk' threshold (< -28 °C).
  • cold_anomaly_frequency: Rate of days/month (between 0-1) where the mean daily wind chill is at or below the 'Low Risk' threshold (< 0 °C) AND below the 5th baseline percentile for that location.
