Digital Earth Pacific Annual Radar Composite (Sentinel-1, GeoMAD, 10 m)

This dataset provides annual radar-based composite imagery derived from Sentinel-1 observations across the Pacific region. Sentinel-1 carries a C-band Synthetic Aperture Radar (SAR), which acquires data day and night and in all weather conditions, so the composite is independent of cloud cover. Multi-temporal Sentinel-1 backscatter observations (VV and VH polarisations) are aggregated into annual geometric median composites, along with median absolute deviation measures (emad, smad and bcmad) and a count of observations. The dataset is available annually from 2017 and supports monitoring of land, water, and environmental change.

(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...
