Infrared Radiometers
The Infrared Radiometer measures remote surface temperatures to
within 0.2 C.
T-FACE: Temperature Free-Air Controlled Enhancement
This type of experiment applies a heating treatment to open-field plant canopies, simulating models of future warmer conditions. Dr. Bruce Kimball of the Arid-Land Agricultural Research Center and colleagues design and operate such experiments. In 2005 they developed a proportional–integrative–derivative control system for controlling the rise in temperatures. Apogee Infrared Radiometers provided the data on control and heated plot temperatures. Similar infrared warming experimentation using this design and Apogee Infrared Radiometer sensors are also underway in Haibei, Qinghai, China and Cheyenne, WY .
