1. Data Content: This dataset contains hourly all-weather land surface temperature (LST) data over the full disk of the FY-4A satellite, along with quality flag data. The temporal coverage spans from June 2018 to June 2023, providing long-term, high-temporal-resolution land surface temperature data.
2. Data Source and Processing Method: The dataset is sourced from the official website of the National Satellite Meteorological Center (NSMC), and was processed using the surface energy balance method.
3. Data Quality Description: For the quality control (QC) data, a pixel with QC=-1 is a fill value, a pixel with QC=0 represents clear-sky land surface temperature, and a pixel with QC=1 represents cloudy-sky land surface temperature.
4. Data Application Achievements and Prospects: This dataset and the corresponding processing method have been published in the journal *IEEE Transactions on Geoscience and Remote Sensing*, with the paper titled *Estimating Hourly All-Weather Land Surface Temperature From FY-4A/AGRI Imagery Using the Surface Energy Balance Theory*
