Global 1 km Resolution Nighttime Land Surface Temperature for 2021

A 63.7 GB seamless global dataset of land surface temperature at 1 km resolution, captured at approximately 1:30 AM. Yuyu Zhou generated this dataset in 2024 by processing NASA MODIS satellite data and applying a novel algorithm to fill missing pixels caused by clouds and shadows. The data is provided in TIF and RTF formats under a CC-BY-4.0 license.

Use Cases

• Modeling urban heat island effects based on global nighttime temperature data.
• Analyzing climate change impacts on land surface temperature patterns.
• Validating and calibrating climate models using satellite-derived temperature observations.
• Studying land-atmosphere energy exchange processes at a 1 km scale.

Strengths

• Seamless global coverage with a high 1 km spatial resolution.
• A novel algorithm was applied to fill missing pixels, likely improving data completeness.
• Large 63.7 GB dataset derived from authoritative NASA MODIS satellite products.
• Explicitly states the observation time as approximately 1:30 AM local time.

Limitations

• Data is for a single year (2021), limiting longitudinal analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description does not specify the accuracy or validation metrics of the gap-filling algorithm.
