Global gridded estimates of the dominant age of the built stock (GHS-AGE)

GHS-AGE consists of spatial raster datasets representing global, gridded estimates of the dominant age of the built stock. GHS-AGE has been derived from a multi-temporal stack of gridded estimates of built-up surface (GHS-BUILT-S R2023A, 1975-2020) that has derived from integrated processing of Sentinel-2 and historical Landsat multispectral data. GHS-AGE estimates represent the epoch in which 50% of the built-up surface of 2020 has been exceeded for the first time, for each grid cell. GHS-AGE enables the global, fine-grained modelling of approximate building construction epoch information using a globally consistent methodology.

(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...
