Let Tule maintain the sensors so you can focus on what you care about.
Tule has the largest measured evapotranspiration (ET) sensor network ever deployed. We have spent years building the infrastructure and team to operate an ET sensor network at scale so you don't have to.
Receive daily data for measured ET as well as daily values for net radiation and sensible heat flux density. Data is quality controlled using lessons learned from processing data from thousands of sensors.
ET is a fundamental measurement of plant health and productivity. Imagine what can be done with it.
Predicting food supply is critical. ET is directly correlated with yield. If you are trying to build accurate yield prediction models, please reach out.
Use our daily crop water stress measurements to ground truth satellite or aerial image-based crop stress models.
Prove to regulators that you are not wasting water based on measurements of actual crop water use.
Water trading will become increasingly important after SGMA groundwater regulations go into effect. Measured ET will be vital to establish a fair and consistent marketplace for water exchange.
PG&E and other utilities have many incentives to help farmers optimize their energy usage. ET is a critical measurement for knowing how much energy can be saved by running pumps less often or at different times.
ET is a fundamental measurement of plant productivity. We look forward to seeing the many different creative applications that people will build with measured ET.

Currently all Tule sensors are in California, but we are open to expanding to new geographies for the right opportunity.
No. Tule ET sensors work in almost any open-air crop. We currently have sensors installed in about 20 crops, including winegrapes, tree nuts, and annual crops.
Yes, group purchasing is a great way make the data more affordable. This often makes sense when growers, researchers, and other organizations want to share the cost of sensors.
We would never sell data without grower consent. In many cases, growers are happy to share their data if it benefits them.
Energy balance components are available in the researcher plan. Daily ET and FieldStat are included in all plans.
Hardware manufacturing is cheaper if you can order batches of 10,000 or more. For large orders, we may be able to pass along these savings.
