Basic descriptions The Global fluvial Sediment Dataset (GSED) provides suspended sediment concentration data at the reach scale worldwide from 1985 to 2020, covering 6,383 river segments with channel widths exceeding 120 meters. This dataset is constructed using Landsat-4/5/7 satellite imagery based on weighted multi-band ratios model, delivering monthly averaged suspended sediment concentration (mg/L) for each

Basic description We developed a satellite-based dataset of global freshwater lake algal blooms from 2003 to 2022, covering 1,956 large lakes and reservoirs , each larger than 50 km². The dataset was derived from global daily observations at 1-km resolution from the MODIS onboard NASA’s Aqua satellite, using all 0.8 million images acquired between 2003

Basic description The Global River Ice Phenology (GRIP) data is organized into three distinct tables. These tables document the annual freeze-up date, break-up date, and ice duration for 7,970 examined river segments determined by IDLRM from 2000 to 2021 in the study. The first column “river_id” is associated with unique identifiers for rivers in the

Basic descriptions This dataset presents the first global vector database of inland and coastal dike-pond systems, capturing the maximum extent of global dike-pond systems from 1984 to 2020, as well as vector data for three distinct periods (1984-2000, 2001-2010, and 2011-2020). Produced using 30-meter resolution Landsat products and a deep learning model, this dataset features

Basic descriptions The Global Coastal Algal Bloom Dataset is derived from daily MODIS satellite images with a resolution of 1 km, totaling 0.76 million images globally, spanning the period from 2003 to 2020. It captures the occurrences of coastal blooms for 126 out of 153 ocean-bordering countries worldwide. Compared to prior global coastal phytoplankton datasets

Basic descriptions The global gridded aerosol models constitute a comprehensive dataset integrating aerosol models on a spatial grid (5° × 5°) at a climatological monthly scale, encompassing a total of 3,207 new aerosol models. These models cover 310 grid cells across global inland and coastal regions, aiming to enhance the precision of atmospheric corrections for

Basic descriptions The “China lake algal bloom” dataset describes the algal bloom conditions in 103 Chinese lakes affected by algal blooms over the past two decades (2003 to 2020). It is a dataset that includes annual scale data of algal bloom occurrence (BO), onset time (Onset), potential occurrence period (POP), and maximum bloom extent (MBE). The dataset was compiled

Basic descriptions The data set mainly includes the ice observation frequency (ICO) of north temperate lakes in four periods from 1985 to 2020, as well as the location, area and elevation of the lakes. Among them, the four time periods are 1985-1998 (P1), 1999-2006 (P2), 2007-2014 (P3) and 2015-2020 (P4) respectively, in order to improve

Basic descriptions The global annual lake ice phenological dataset includes the freeze-up date, break-up date, and ice duration for 74,245 lakes in the northern hemisphere. The dataset is divided into three parts: 1) current data, obtained from MODIS productions through a DLRM model (with parameters provided), covering the period of 2001 to 2020; 2) historical and
