Table 1. Channel characteristics of the AVHRR/2

               Wavelength
Channel    interval (micrometer)             Signal        
-------    ---------------------    ------------------------
   1             ~0.6-~0.7          Reflected solar energy
   2             ~0.7-~1.1          Reflected solar energy
   3             ~3.5-~4.0          Reflected solar energy +
                                      thermal emission
   4            ~10.3-~11.3         Thermal emission
   5            ~11.5-~12.5         Thermal emission

Note that the AVHRRs on TIROS-N, NOAA-6, NOAA-8, and
NOAA-10 were constructed without Channel 5.
