LISST-Holo concentration limits
[Sequoia, June 7, 2011]
The article ‘LISST Concentration Limits‘ describes how to compute the upper concentration limits for the LISST instruments. However, the results in that article does NOT apply to Sequoia’s...

get_bf.m
[Sequoia, April 5, 2011]
This MATLAB script allows the LISST-100 or LISST-100X user to compute the part of the forward scattering coefficient, bf, covered by the angle ranges of the LISST-100X. See the application note ‘Angles...
