Query: Effect of the instrument slit function on upwelling radiance from a
  wavelength dependent surface reflectance   The Radiance Enhancement (RE) method was introduced for efficient detection
of clouds from the space. Recently we have also reported that due to high
reflectance of combustion-originated smokes this approach can also be
generalized for detection of the forest fires by retrieving and analyzing
datasets collected from a space orbiting micro-spectrometer operating in the
near infrared spectral range. In our previous publication we have performed a
comparison of observed and synthetic radiance spectra by developing a method
for computation of surface reflectance consisting of different canopies by
weighted sum based on their areal coverage. However, this approach should be
justified by a method based on corresponding proportions of the upwelling
radiance. The results of computations we performed in this study reveals a good
match between areal coverage of canopies and the corresponding proportions of
the upwelling radiance due to effect of the instrument slit function.
