FY-3D Land Surface Temperature: Global Daily Seamless Dataset, 2019-2025

A global, daily, and spatially seamless daytime and nighttime FY-3D Land Surface Temperature (LST) dataset generated by Yanling You using the OESTR model. The dataset covers the period from 30 April 2019 to 31 December 2025 and is hosted on figshare. It was last updated on 9 April 2026.

Use Cases

• Climate trend analysis based on daily, global temperature observations.
• Environmental process modeling based on seamless daytime and nighttime land surface temperature data.
• Validating other satellite-derived temperature products based on the FY-3D passive microwave sensor source.
• Studying urban heat island effects based on spatially continuous temperature maps.

Strengths

• Provides spatially seamless data, addressing a key limitation of spatiotemporal gaps in raw observations.
• Covers a significant time range from April 2019 to December 2025.
• Includes both daytime and nighttime observations, enabled by a joint training strategy.
• Uses an all-weather observation source (FY-3D passive microwave sensors).

Limitations

• The dataset is extremely small (1.9 KB), suggesting it may contain only metadata or a description, not the actual data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
