To better quantify the seasonal changes in canopy structure and physiological status (e.g. photosynthetic capacity or efficiency), and provide a more rigorous context for interpretation of the camera data, we installed an extensive set of radiometric instruments on the Harvard Forest Barn Tower beginning in 2011. A complete list of sensors is given in the Methods section. Note that these include both broad-band and narrow-band sensors, and sensors with hemispherical, narrow, and multi-angular fields of view.
