NIDIS Soil Moisture/Temperature Sensor Network with USCRN
Since 2009, NIDIS has supported the development of and research based on a high-quality soil moisture monitoring network, the NOAA U.S. Climate Reference Network (USCRN), including the procurement of soil moisture sensors, installation, data acquisition and integration, data ingest, and quality control/quality assurance for 113 stations in the coterminous U.S. and Alaska. Several research products are being developed using this real-time in-situ soil moisture data to support operational drought monitoring, experimental land surface modeling, and operational hydrological modeling.
