DaYu-GCP: DaYu all-day global cloud physical properties products with 0.07° resolution retrieved from geostationary satellite imagers covering the period from 2000 to 2022

This study utilises global geostationary satellite thermal infrared channel brightness temperature data assembled from the Gridded Satellite (GridSat-B1) project. Employing the single-layer cloud retrieval model small attention-UNet (CloudSmaAtUNet) within the DaYu CLoud Analysis System (DaYu-CLAS), we have retrieved the first set of all-day Global Cloud physical properties Products (GCP) featuring a temporal resolution of 3 hours, spatial resolution of 0.07°, covering all regions from -70° to 70° and -180° to 180°, and a temporal span of 23 years (2000–2022). We named this dataset as the DaYu-GCP. The DaYu-GCP is retrieved using infrared brightness temperatures at 6.7 µm and 11 µm. The dataset include four variables: cloud phase (CLP), cloud top height (CTH), cloud optical thickness (COT), and cloud effective radius (CER).Detailed information:3h temporal resolution is UTC time 0, 3, 6, 9, 12, 15, 18, and 21 hours daily.CLP: 0 clear, 1 liquid, 2 ice; missing: NaN.CTH: CTH in km; missing: NaN; range [0, 18].COT: COT in unitless; missing: NaN; range [0, 150].CER: CER in µm; missing: NaN; range [0, 60]. The file names and directory structure are organized in the following format:```{year}.tar.gz/{year}{month}{day}{hour}.nc```# CitationThe paper was published in Earth System Science Data.DOI: https://doi.org/10.5194/essd-18-1813-2026## change list:V1: Init commit.V2: Rename.V3: Add citation information.
