This dataset contains annual, summertime, and wintertime surface urban heat island (SUHI) intensities for day and night for over 10,000 urban clusters throughout the world. The dataset was created using the MODIS 8-day TERRA and AQUA land surface temperature (LST) products, the Landscan urban extent database, the Global Multi-resolution Terrain Elevation Data 2010, and the European Space Agency (ESA) Climate Change Initiative (CCI) land cover data using the Simplified Urban-Extent Algorithm. The product is available both at the pixel level (at 300 m resolution after downscaling) and as urban cluster means from 2003 to 2018. The monthly composites are only available as urban cluster means.

A summary of older versions, including changes from the dataset created and analyzed in the originally published manuscript can be found on the Yale Center for Earth Observation website. The dataset can also be explored using the Global Surface UHI Explorer web application.

The dataset is split into the following six components:

  1. UHI_all_averaged: Image containing cluster-mean composite daytime and nighttime SUHI intensity for annual, summer, and winter.

  2. UHI_monthly_averaged: Image containing cluster-mean monthly composites of daytime and nighttime SUHI intensity.

  3. UHI_yearly_averaged: Image collection of cluster-mean yearly composites of daytime and nighttime SUHI intensity from 2003. to 2018.

  4. UHI_yearly_pixel: Image collection of spatially disaggregated (nominal scale of 300 m) annual daytime and nighttime SUHI intensity from 2003 to 2018.

  5. Summer_UHI_yearly_pixel: Image collection of spatially disaggregated (nominal scale of 300 m) summertime daytime and nighttime SUHI intensity from 2003 to 2018.

  6. Winter_UHI_yearly_pixel: Image collection of spatially disaggregated (nominal scale of 300 m) wintertime daytime and nighttime SUHI intensity from 2003 to 2018.

This asset is the second component.
