Pyspectral is a package to read and manipulate satellite sensor spectral responses and solar irradiance spectra
I am interested to study the effect of spectral response functions of different satellites on the calculated brightness temperature. What I need is to provide a blackbody (in the easiest...
I applied atmospheric correction to a satellite image. having negative reflectance is not reasonable based on its definition. I understand that the main reason is atmospheric data which we use...

# Background The built-in method (reduce_rayleigh_highzenith)](https://github.com/pytroll/pyspectral/blob/main/pyspectral/rayleigh.py#L287) offers a way to _linearly_ reduce the Rayleigh correction at high sun zenith angles in order to compensate for the fact that RTM models...
Hi, thanks for your excellent work. I have a question: what's the unit of Rayleigh reflectance? Here is the sample code to get Rayleigh reflectance: ----------------------------------------------------------- >>> from pyspectral.rayleigh import...
Could I obtain Correction reflectance by Rayleigh in numpy array for an entire image of Landsat 8? I would like to obtain channels 2,3,4,5. I saw issue #90 where there...
As discussed on slack and #159, there used to be a `np.nan_to_num` call applied to the correction array returned by Rayleigh correction. The idea was that if the correction calculations...
#### Problem description `tb2rad_dir` config option used here https://github.com/pytroll/pyspectral/blob/main/pyspectral/near_infrared_reflectance.py#L111 is not described in the config section eg. https://pyspectral.readthedocs.io/en/latest/installation.html#configuration-file I figured out, but would be nice to have the documentation for...
