Patna City Urban Heat Map
Urban heat maps highlight the rising temperatures in cities due to factors like reduced vegetation and increased urbanization. Below are some key indicators for Patna City:
Land Surface Temperature
Rising land surface temperatures contribute to urban heat islands, impacting the environment and public health.
NDVI (Normalized Difference Vegetation Index)
NDVI measures vegetation health. Reduced vegetation in urban areas exacerbates heat retention.
Emissivity
Emissivity indicates the efficiency of surfaces emitting heat. Urban materials often have higher emissivity.
Harmful Effects
- Increased energy consumption for cooling.
- Higher air pollution and greenhouse gas emissions.
- Adverse health effects, especially for vulnerable populations.
- Reduced water quality due to thermal pollution.
