Temporal Analysis

  • Date and Time: Study the temporal patterns of fire occurrences to identify any trends, such as seasonal variations or diurnal patterns.
  • Daytime vs. Nighttime: Compare fires detected during the daytime and nighttime to understand if there are any differences in fire activity based on illumination conditions.

Satellite Analysis

  • Two Types of Satellite: Compare fire detections from different satellite systems to assess the consistency and reliability of fire observations. Identify any variations or discrepancies in fire detection between the two satellite types.

Fire Characteristics

  • Type of Fire: Classify fires based on their characteristics, such as wildfire, agricultural burning, or urban fires. This information can provide insights into the sources and causes of the fires.
  • Brightness Temperature: Analyze the brightness temperature values associated with the fire pixels to understand the fire’s thermal intensity and distribution. Higher brightness temperatures can indicate more intense fires.
  • Fire Radiative Power (FRP): FRP quantifies the amount of energy released by a fire. Analyze the FRP values to assess the fire’s energy output, intensity, or potential impact.
  • Confidence: Evaluate the confidence level associated with each fire detection. Higher confidence levels indicate more reliable detections. Analyze spatial patterns of confidence levels to identify areas with more accurate fire observations.

Three main reasons cause the fire event in Taiwan

Weather Conditions

In Taiwan, winter is typically characterized by cooler temperatures and lower humidity. These weather conditions can lead to drier vegetation, which may increase the potential for fires to ignite and spread more easily.

Agricultural Burning

In some regions of Taiwan, agricultural burning is a common practice, especially during the winter months. Farmers may burn crop residues or engage in land clearing activities. This increased burning activity during winter can give the impression of stronger fires during that season.

Human Activities

Human activities, such as outdoor recreational activities or increased use of heating devices, can also contribute to fire incidents. These activities might be more prevalent during the winter months, which could result in a higher number of fire events.
