Digital Earth Pacific Water Observations from Space (WOfS, Landsat, 30 m)

Water Observations from Space (WOfS) maps the presence of surface water across the Pacific region using Landsat satellite imagery, highlighting where water is usually present and where it is rarely present. The dataset supports flood mapping, drought monitoring, hydrological analysis, and water resource management. It comprises three products: - Scene-based Surface Water: per-scene classification of surface water presence, derived from Landsat imagery using water detection algorithms, from 1984 onwards. - Annual Summary: annual statistics of wet and clear observation counts and water frequency, capturing interannual variability...

(EXPERIMENTAL) NOAA FourCastNet Global Forecast System (FourCastNetGFS) (EXPERIMENTAL)

The FourCastNet Global Forecast System (FourCastNetGFS) is an experimental system set up by the National Centers for Environmental Prediction (NCEP) to produce medium range global forecasts. The model runs on a 0.25 degree latitude-longitude grid (about 28 km) and 13 pressure levels. The model produces forecasts 4 times a day at 00Z, 06Z, 12Z and 18Z cycles. Major atmospheric and surface fields including temperature, wind components, geopotential height, relative humidity and 2 meter temperature and 10 meter winds are available. The products are 6 hourly forecasts up to 10 days. The data format is GRIB2. The FourCastNetGFS...

10m Annual Land Use Land Cover (9-class)

This dataset, produced by Impact Observatory, Microsoft, and Esri, displays a global map of land use and land cover (LULC) derived from ESA Sentinel-2 imagery at 10 meter resolution for the years 2017 - 2024. Each map is a composite of LULC predictions for 9 classes throughout the year in order to generate a representative snapshot of each year. This dataset was generated by Impact Observatory, which used billions of human-labeled pixels (curated by the National Geographic Society) to train a deep learning model for land classification. Each global map was produced by applying this model to the Sentinel-2 annual scene...
