Ahmedabad's Land Surface Temps Soar 3.4°C
12 May
Summary
- Land surface temperatures in Ahmedabad increased by 3.4°C over three decades.
- Summer mean temperatures rose from 36.47°C (1995) to 39.87°C (2025).
- Studies correlate rising LST with urban growth and loss of vegetation.
Ahmedabad has witnessed a substantial increase in land surface temperature (LST) over the past three decades, contributing to unbearable summer heat. A comprehensive study projects a rise of 3.4 degrees Celsius in LST between 1995 and 2025. Researchers meticulously analyzed Landsat data, including LST and the Normalized Difference Built-up Index, to track these changes.
Seasonal analyses reveal that average summer LST increased from 36.47°C in 1995 to an anticipated 39.87°C by 2025. Winter LST also saw a significant jump, from 23.14°C to 29.53°C. This trend, distinct from general air temperatures, is closely tied to urban development, loss of green spaces, and the urban heat island effect.
Further data from OpenCity indicates an average maximum temperature rise from 37.1°C (1995-2004) to 38.4°C (2015-2024). Recent analyses also show a rise in pre-monsoonal heat stress, from 39.32°C in 2014 to 41.29°C in 2023. These findings underscore the urgent need for multi-variable, heat-resilient urban planning strategies.
