Satellite Data for Hydrology & Water Engineering

ESA's TanDEM-X-derived global DEM — the most accurate free global surface model available today.

Copernicus DEM with forests and buildings stripped out — the bare-earth DEM flood and drainage models actually want.

Gauge-blended satellite rainfall at 0.05°, daily, since 1981 — the standard for drainage work in data-sparse regions.

NASA's 30-minute, 0.1° global precipitation record — the highest time resolution of any satellite rainfall product.

ECMWF's hourly global reanalysis — the default gap-free climate forcing record for ungauged catchments worldwide.

1km daily/8-day land surface temperature from MODIS — the standard thermal input for energy-balance ET and snowmelt.

NASA's L-band radiometer soil moisture mission — 9km/36km near-surface moisture, daily, since 2015.

500m daily/8-day global snow-cover extent from MODIS — the standard optical snow product for basin-scale tracking.

Global 10m land cover from Sentinel-1/2 — the highest-resolution free global land cover map available.

Pixel-level surface water history since 1984, built from the entire Landsat archive — where water has been, and when.

Monthly total water storage change from satellite gravity — the only direct signal of large-scale groundwater depletion.

Planetary-scale geospatial analysis in the cloud — the data catalogue and compute behind modern water remote sensing.
