Global 1 km Resolution Daytime Land Surface Temperature Data for 2021

2021 global land surface temperature data at 1 km resolution, captured at approximately 1:30 PM local time. The dataset was generated by Yuyu Zhou from NASA Terra and Aqua satellite MODIS products and uses a novel algorithm to fill missing pixels caused by clouds and shadows. It is a seamless 71.5 GB dataset available in TIF and RTF formats.

Use Cases

• Modeling urban heat island effects based on the global 1 km resolution land surface temperature data.
• Analyzing diurnal temperature patterns based on the consistent 1:30 PM local time observation.
• Validating climate models based on the satellite-derived, gap-filled global temperature dataset.
• Studying land cover change impacts on surface temperature based on the seamless, gap-filled data.

Strengths

• 71.5 GB dataset providing a large-scale, high-resolution global view.
• 1 km spatial resolution offers detailed analysis capabilities.
• Algorithm addresses missing data from clouds and shadows, improving data completeness.
• Data is derived from authoritative NASA MODIS satellite products.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is for a single year (2021), limiting longitudinal analysis.
