Apogee Instruments - Model NDVI -NDVI and PRI Sensors (NDVI)

Apogee’s NDVI sensors are designed to measure reflectance in red and near infrared wavebands to calculate the normalized difference vegetation index (NDVI). NDVI is a measurement of plant greenness correlated with canopy chlorophyll content and leaf area that is used to monitor green-up in the spring and senescence in the fall.
