Next generation system for real-time monitoring of rainfall, soil moisture, and soil temperature

Here we present our work on an environmental sensing network that we have been developing over a number of years at The University of Iowa. Sponsored by the Iowa Flood Center, the system consists of instrumentation that measures rainfall, soil moisture, and soil temperature. Field instrumentation relays data via cellular modems to a central server. Users can access the data through a web browser, and programmatic interfaces allow for ingestion of the data into computational models for flood forecasting.
