historic data availability
description
Measures the amount of water held in the soil, providing a key insight into water availability for plants. This data, with a 1km resolution, is vital for agriculture, enabling the monitoring of drought conditions and the optimization of irrigation. It is also a fundamental input for hydrological models used in flood forecasting and water resource management.
methodology
Soil moisture content is monitored using a combination of satellite data sources, including passive microwave data (from SMAP and SMOS), thermal data (from Landsat, MODIS, and Sentinel 3), and optical data (from Sentinel 2). These data streams are integrated using a spatial downscaling algorithm, resulting in an up-to-daily time-series of volumetric soil moisture content since 2018, at 1km resolution.
