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 sensors are also underway in Haibei, Qinghai, China and Cheyenne, WY .
