(/««) 
Plant Canopy Relationship 
TM 1 
0.45 - 0.52 
Region of maximum chlorophyll and carotenoid 
absorption. Strong relationship between spectral 
reflectance and plant pigment concentration. 
TM 2 
0.52-0.60 
Green vegetation reflection peak. Slight sensitivity 
to plant chlorophyll concentration. 
TM 3 
0.63 - 0.69 
Strong chlorophyll absorption region. Strong 
relationship between spectral reflectance and 
plant chlorophyll concentration. 
TM 4 
0.76 - 0.90 
High vegetation reflectance. Strong relationship 
between spectral reflectance and vegetation 
density and vigor. 
TM 5 
and 
1.55 - 1.75 
Reflection peaks within the water absorption 
region of the shortwave infrared. Both bands 
TM 7 
2.08 - 2.35 
are highly sensitive to leaf water content. 
TM 6 
10.40 - 12.50 
Leaf Temperature and Emisivity.
