Know your field's water content

High resolution nowcasts of water content in soil based on a handful of sensors, or even no sensors at all.
Coverage anywhere in the continental United States.

How It Works

Nowcasts of soil water content leverage a fusion of extensive historical and real-time data, fed through a series of rigorously tested models.

 Soil Texture

Proportions of sand, silt, and clay determine porosity and drying rate


We model drainage paths across a given field, determining where water content will accumulate


Seasonal climatic patterns, aridity, and runoff sources impact evaporation


Recent rainfall drives current water content levels in soil

Integrate our water content estimates into your own analytics systems or into standalone applications like Microsoft Excel. Calls to the REST API take the form of HTTP GET requests:

By default, responses are returned as CSV:

timestamp, lat, lon, vwc
2016-06-02T11:00Z, 42.4326, -93.5880, .238
2016-06-03T11:00Z, 42.5418, -93.3911, .382
2016-06-04T11:00Z, 42.6375, -93.2215, .383

The API can also return JSON, video (.mp4), and Google Earth (.kmz)


Evan Coopersmith, PhD

Evan is an expert in soil water content modeling, who has worked with NASA, CDC, NOAA, and the USDA's Hydrology and Remote Sensing Laboratory. He holds a Ph.D. in Civil and Environmental Engineering from the University of Illinois and a B.S. in Operations Research and Financial Engineering from Princeton.

He has produced numerous publications applying machine learning algorithms to soil water content estimation, comparing sensor technologies, quantifying instrument error, validating satellite-based remote sensing, and describing American hydroclimatology. Previously, his algorithms traded profitably during the 2008-2009 financial meltdown, while he served as co-founder of a hedge fund at the New York Mercantile Exchange.
