Global Daytime Land Surface Temperature at 1 km Resolution, 2023

71.5 GB of seamless global land surface temperature data for 2023. Yuyu Zhou generated this dataset from NASA MODIS satellite products using a novel algorithm to fill missing pixels caused by clouds and shadows. The data provides daytime (1:30 PM) measurements at a 1 km resolution.

Use Cases

• Modeling climate change impacts based on global land surface temperature data.
• Analyzing urban heat island effects based on high-resolution temperature measurements.
• Validating and improving satellite data processing algorithms based on the novel gap-filling method.
• Studying diurnal temperature patterns based on consistent daytime (1:30 PM) observations.

Strengths

• 71.5 GB dataset indicates a large-scale, high-resolution global coverage.
• Seamless coverage achieved via a novel algorithm that fills missing pixels from clouds and shadows.
• Derived from authoritative NASA MODIS satellite products (MOD11A1 and MYD11A1).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to daytime (1:30 PM) observations, not a full diurnal cycle.
• Row count is unknown, which may limit suitability assessment.
