The dataset was created using the MODIS 8-day TERRA and\nAQUA land surface temperature (LST) products, the Landscan urban extent\ndatabase, the Global Multi-resolution Terrain Elevation Data 2010, and the\nEuropean Space Agency (ESA) Climate Change Initiative (CCI) land cover data\nusing the Simplified Urban-Extent Algorithm. The product is available both at\nthe pixel level (at 300 m resolution after downscaling) and as urban cluster\nmeans from 2003 to 2018. The monthly composites are only available as urban\ncluster means.\n\nA summary of older versions,\nincluding changes from the dataset created and analyzed in the originally\npublished manuscript can be found on the\n[Yale Center for Earth Observation website](https://yceo.yale.edu/research/global-surface-uhi-explorer).\nThe dataset can also be explored using the [Global Surface UHI\nExplorer web application](https://yceo.users.earthengine.app/view/uhimap).\n\nThe dataset is split into the following six components:\n\n1. **UHI_all_averaged:** Image containing cluster-mean\n composite daytime and nighttime SUHI intensity for annual, summer,\n and winter.\n\n2. **UHI_monthly_averaged:** Image containing cluster-mean\n monthly composites of daytime and nighttime SUHI intensity.\n\n3. **UHI_yearly_averaged:** Image collection of cluster-mean\n yearly composites of daytime and nighttime SUHI intensity from 2003.\n to 2018.\n\n4. **UHI_yearly_pixel:** Image collection of spatially\n disaggregated (nominal scale of 300 m) annual daytime and nighttime\n SUHI intensity from 2003 to 2018.\n\n5. **Summer_UHI_yearly_pixel:** Image collection of spatially\n disaggregated (nominal scale of 300 m) summertime daytime and\n nighttime SUHI intensity from 2003 to 2018.\n\n6. **Winter_UHI_yearly_pixel:** Image collection of spatially\n disaggregated (nominal scale of 300 m) wintertime daytime and\n nighttime SUHI intensity from 2003 to 2018.\n\nThis asset is the second component.\n\n### Bands\n\n\n**Pixel Size**\n\n300 meters\n\n**Bands**\n\n| Name | Units | Pixel Size | Description |\n|-----------------|-------|------------|-------------------------|\n| `Jan_day_UHI` | °C | meters | January Daytime UHI |\n| `Jan_night_UHI` | °C | meters | January Nighttime UHI |\n| `Feb_day_UHI` | °C | meters | February Daytime UHI |\n| `Feb_night_UHI` | °C | meters | February Nighttime UHI |\n| `Mar_day_UHI` | °C | meters | March Daytime UHI |\n| `Mar_night_UHI` | °C | meters | March Nighttime UHI |\n| `Apr_day_UHI` | °C | meters | April Daytime UHI |\n| `Apr_night_UHI` | °C | meters | April Nighttime UHI |\n| `May_day_UHI` | °C | meters | May Daytime UHI |\n| `May_night_UHI` | °C | meters | May Nighttime UHI |\n| `Jun_day_UHI` | °C | meters | June Daytime UHI |\n| `Jun_night_UHI` | °C | meters | June Nighttime UHI |\n| `Jul_day_UHI` | °C | meters | July Daytime UHI |\n| `Jul_night_UHI` | °C | meters | July Nighttime UHI |\n| `Aug_day_UHI` | °C | meters | August Daytime UHI |\n| `Aug_night_UHI` | °C | meters | August Nighttime UHI |\n| `Sep_day_UHI` | °C | meters | September Daytime UHI |\n| `Sep_night_UHI` | °C | meters | September Nighttime UHI |\n| `Oct_day_UHI` | °C | meters | October Daytime UHI |\n| `Oct_night_UHI` | °C | meters | October Nighttime UHI |\n| `Nov_day_UHI` | °C | meters | November Daytime UHI |\n| `Nov_night_UHI` | °C | meters | November Nighttime UHI |\n| `Dec_day_UHI` | °C | meters | December Daytime UHI |\n| `Dec_night_UHI` | °C | meters | December Nighttime UHI |\n\n### Terms of Use\n\n**Terms of Use**\n\n[CC-BY-4.0](https://spdx.org/licenses/CC-BY-4.0.html)\n\n### Citations\n\nCitations:\n\n- Chakraborty, T., \\& Lee, X.
