This section describes the sensors deployed on the Lemnatec Field Scanner in Maricopa, AZ. Device and sensor information, including technical specifications, calibration data, and calibration targets are stored in the TERRA REF Clowder database.
The Maricopa field site is located at the the University of Arizona Maricopa Agricultural Center and USDA Arid Land Research Station in Maricopa, Arizona. At this site, we have deployed the following phenotyping platforms.
The Lemnatec Scanalyzer Field System is the largest field crop analytics robot in the world. This high-throughput phenotyping field-scanning robot has a 30-ton steel gantry that autonomously moves along two 200-meter steel rails while continuously imaging the crops growing below it with a diverse array of cameras and sensors.

The Bellwether Foundation Phenotyping Facility at the Donald Danforth Plant Science Center, Missouri is a climate controlled 70 m2 growth house with a conveyor belt system for moving plants to and from fluorescence, color, and near infrared imaging cabinets. This automated, high-throughput platform allows repeated non-destructive time-series image capture and multi-parametric analysis of 1,140 plants in a single experiment.
