Land Surface Temperature Trends: Ahmedabad vs. Delhi (2013–2023)
- The Urban Heat Island (UHI) effect by analyzing the Land Surface Temperatures (LST) of Ahmedabad and Delhi—two cities close to my heart.
- The timeline set for this analysis was: 2013 as the starting point, marking a 10-year study period, 2016 as the year of departure from India for USA, and 2023 as the most recent visit.
- Data collected from satellite data from Google Earth Engine to retrieve cloud and temperature data, and weather records from airport meteorological databases for cross-validation.
- Cloud data was filtered out using Google Earth Engine to make sure the temperature results were accurate.
- Heat maps were created for Ahmedabad and Delhi using ArcGIS Pro, and the distribution of heat across them was analyzed visually.
- Results of the project showed that Ahmedabad has become much hotter over the past 10 years, especially in May, while Delhi remains warm due to its dense population and infrastructure.
- The data highlighted how green spaces and vegetation help cool cities, and parks and green spaces were found to be cooler, shown in green or blue.
- To make cities more livable, there is a need to focus on creating more parks, planting trees, and protecting green spaces.
- The project brought forward the impact of rapid urbanization on the environment and the climate and left us with a reminder of how much the landscape has changed.
- It also showed the importance of analyzing and understanding the factors that contribute to the Urban Heat Island (UHI) effect for making cities more livable.
