Table 3. Meteorological stations in Istanbul and their temperature data with radiance values. 
The relationship between radiance and the temperature is given 
in the Figure 12. There is a linear relation between radiance 
values and temperature data in a good agreement. 
Correlation of radiance values and temperature data is %88 and 
its formula is: y = 0,222x + 0,339.
