WebThis index uses reflectance from a red band around 0.66 μm and a near-Infrared band around 0.86 μm. The red band is found in the absorption region of the chlorophyll, while the near-IR band is used in high reflectance plateau of the vegetation canopies. These two bands sense different depths over the vegetation canopies. WebFletcher-Index. Dieser Wert gibt die Hörfähigkeit im mittleren Frequenzbereich zwischen 500 und 4.000 Hertz an.
