Free Virtual Seminar: Basic Principles of Radiation Measurement to Predict ET, Climate Change, Photosynthesis, and Crop Yield
Title: Basic Principles of Radiation Measurement to Predict ET, Climate Change, Photosynthesis, and Crop Yield
Presenter: Dr. Bruce Bugbee
Measurement of net radiation is a critical component of the prediction of evapotranspiration and the temperature of our planet. Net radiation includes 4 components:
- Incoming shortwave radiation
- Reflected shortwave radiation
- Incoming longwave radiation
- Outgoing longwave radiation
Several new instruments have become available over the past few years to measure net radiation, but it is not always necessary to measure each radiation component separately. For many applications, a measurement of incoming shortwave radiation can be coupled with a model to predict net radiation.
This presentation will discuss these methods, as well as the following:
- The sensors used for measuring photosynthetic photon flux, a measurement which can determine photosynthesis, plant growth, and yield.
- Tools and techniques to improve the accuracy of estimating plant growth and yield based on absorbed radiation.
Dr. Bruce Bugbee teaches Crop Physiology and Plant Nutrition at Utah State University where he was awarded the Graduate Mentor of the Year award in 2001 and Researcher of the Year award in 2005. He is a past Chairman of the Crop Physiology division of the American Society of Agronomy, and a past Chair of the NCR-101 Controlled Environment committee. He has been awarded continuous competitive funding from NASA for the past 28 years to study the physiology of food crops in controlled environments. He is the author of over 100 referred journal articles and book chapters. In 1996 he founded Apogee Instruments, a company dedicated to helping people make environmental measurements.
