Free Virtual Seminar: NDVI & PRI: Measurement Theory, Methods, and Applications
NDVI & PRI: Measurement Theory, Methods, and Applications
NDVI (the normalized difference vegetation index) is correlated with biomass, canopy structure (eg., LAI), and foliar chlorophyll content. PRI (photochemical reflectance index) is emerging as a useful vegetation index for estimating plant canopy photosynthetic light use efficiency. Combined, NDVI and PRI provide insight into canopy structure and physiological function, key components of plant canopy productivity.
In this virtual seminar, canopy researcher Dr. Steve Garrity gives an overview of how and why to measure NDVI and PRI. He will cover:
- The basics of multi-band radiometers
- What NDVI can reveal about plant canopy structure
- What PRI is and how it is used to estimate light use efficiency
- How to measure NDVI and PRI at the plot scale using Decagon’s new Spectral Reflectance Sensors
- Typical measurement scenarios and sampling protocols
