Global 1 km Resolution Nighttime Land Surface Temperature Dataset for 2024

A 2024 global dataset of land surface temperature (LST) at 1:30 AM local time, with a 1 km resolution. It was generated by Yuyu Zhou from NASA Terra and Aqua satellite MODIS products (MOD11A1 and MYD11A1) using a novel algorithm to fill missing pixels caused by clouds and shadows. The dataset is available in TIF and RTF formats and totals 63.6 GB in size.

Use Cases

• Modeling urban heat island effects based on global nighttime temperature data.
• Analyzing land surface temperature trends and anomalies for climate research.
• Validating and calibrating other thermal remote sensing products or climate models.
• Studying diurnal temperature variations by comparing with daytime LST datasets.

Strengths

• Seamless global coverage at a high 1 km spatial resolution.
• Uses a novel algorithm to fill missing pixels from the original MODIS data, improving data completeness.
• Large dataset size of 63.6 GB indicates detailed spatial information.

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.
• The dataset is for a single year (2024), limiting longitudinal analysis.
