Comparisons of Brightness Temperatures of Landsat-7/ETM+ and Terra/MODIS around Hotien Oasis in the Taklimakan Desert

Table 5

Calibration constants of the TIR band of Landsat-7/ETM+ for converting calibrated digital numbers to observed spectral radiance.

Band	𝐿max𝜆; (W/(m^2⋅sr⋅μm))	𝐿min𝜆; (W/(m^2⋅sr⋅μm))	𝐺rescale; (W/(m^2⋅sr⋅μm)/𝑄cal)	𝐵rescale; (W/(m^2⋅sr⋅μm))
6 (Low gain); 6 (High gain)	0.0; 3.2	17.04; 12.65	0.067087; 0.037205	−0.07; 3.16

Note that 𝑄_cal is calibrated digital numbers.
