2026-03-26 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 doi:10.57760/sciencedb.26292 en 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. all-day global cloud physical properties; long-term; cloud properties; geostationary satellite; DaYu Lingxiao Zhao Feng Zhang Zhijun Zhao Feng Lu Jingwei Li Bin Guo Wenwen Li PUBLIC https://opendatacommons.org/licenses/by/1-0/ dataset http://www.doi.org/10.5194/essd-18-1813-2026 Science Data Bank
