Global Daytime Land Surface Temperature at 1 km Resolution in 2022

71.4 GB of raster data provides a seamless global map of daytime land surface temperature. The dataset was generated by Yuyu Zhou using NASA Terra and Aqua satellite MODIS products and a novel algorithm to fill missing pixels. It was last updated on April 17, 2026.

Use Cases

• Modeling urban heat island effects based on global land surface temperature data
• Monitoring climate change impacts on land temperature patterns
• Validating regional climate models using satellite-derived temperature observations
• Analyzing agricultural or ecological stress based on surface temperature variations

Strengths

• Dataset size is 71.4 GB, indicating substantial spatial coverage and detail
• Data has a high 1 km resolution for global land surface temperature
• A novel algorithm was applied to fill missing pixels caused by clouds and shadows

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data represents only daytime (1:30 PM) observations, not diurnal cycles
• Row count is unknown, which may limit suitability assessment
