Global 1 km Resolution Nighttime Land Surface Temperature for 2022

63.5 GB of seamless, 1 km resolution global land surface temperature data for 2022, captured at approximately 1:30 AM. The dataset was created by Yuyu Zhou from NASA Terra and Aqua satellite MODIS products, using a novel algorithm to fill missing pixels caused by clouds and shadows. The data was last updated on 2026-04-17.

Use Cases

• Modeling urban heat island effects based on global nighttime temperature data.
• Analyzing land surface temperature patterns and anomalies for climate studies.
• Validating and calibrating other lower-resolution climate models using the 1 km resolution data.
• Studying the impact of cloud cover on temperature measurements using the gap-filling algorithm.

Strengths

• 63.5 GB dataset indicates a large-scale, high-resolution global coverage.
• Uses a novel algorithm to fill missing pixels, likely improving data completeness.
• Derived from NASA's authoritative MODIS satellite products (MOD11A1 and MYD11A1).
• Provides a specific temporal snapshot (2022) at a consistent local time (1:30 AM).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's large size (63.5 GB) may pose storage and processing challenges.
• Data may reflect geographic or temporal bias inherent to the source satellites and the single year of coverage.
