Seeking References for “near_infrared_reflectance”

Hello,

I would like to inquire whether there is any reference literature related to near_infrared_reflectance. I intend to cite it in my paper. Could you please provide some advice? Thank you.

Best regards,

Hi!

Thanks for reaching out! We have been using this kind of 3.7-3.8 micron reflectance derivation for decades and is using it in our NWCSAF/PPS cloud mask and type, see here (if I may be so selfish to refer to our ancient paper on PPS):
[1] A. Dybbroe, K.-G. Karlsson, and A. Thoss, ‘NWCSAF AVHRR Cloud Detection and Analysis Using Dynamic Thresholds and Radiative Transfer Modeling. Part I: Algorithm Description’, Journal of Applied Meteorology and Climatology, vol. 44, no. 1, pp. 39–54, Jan. 2005, doi: 10.1175/JAM-2188.1.

But we refer to the derivation exlained in:
[1] R. C. Allen, P. A. Durkee, and C. H. Wash, ‘Snow/Cloud Discrimination with Multispectral Satellite Measurements’, Journal of Applied Meteorology and Climatology, vol. 29, no. 10, pp. 994–1004, Oct. 1990, doi: 10.1175/1520-0450(1990)029<0994:SDWMSM>2.0.CO;2.

You are always welcome to link to Pyspectral on Github, PyPI or Conda-forge as well of course. :-)

And of course (as I guess you already know) you have the documentation on how we derive it here as well:

Thank you very much for your response!

The formulas detailed in the Pyspectral documentation are also very thorough.
I've been looking for the related papers for several days, and the references you provided are extremely helpful!
