LISST-200X User’s ManualAppendix D: Processing Data Files Using MATLAB Page 105
Internal instrument relative humidity (%)
Accelerometer X, Y, and Z (not presently calibrated or used)
Raw data as it appears in the RBN file
The factory background (corrections applied to aux data)
User collected background (corrections applied to aux data)
Counts of ambient light removed from ring values
Structure containing various instrument information
Vector to convert cscat to estimated total area concentration
Vector to convert cscat to estimated total volume concentration
The second function inverts the corrected scattering to a particle size distribution. The
syntax is as follows:
The first argument is the corrected scattering (cscat) from the structure returned from
‘getscat_L200X.’ The following three argument are set to zero or one.
Random – If set to 1, the randomly shaped particle matrix is used to invert the data. If set to
zero, the spherical particle matrix is used. See Appendix G: Spherical and Random Shape
Particle Models for more information.
Sharpen – If set to 1, the function checks the width of the size distribution and increases the
number iterations if the size distribution is wide (recommended).
ShowProgressBar – If set to 1, a progress bar will display the processing status.
The function will return the volume distribution in uL/L (vd) and the midpoint of each size bin
in microns (dias).
[vd, dias] = invert_L200X(Cscat,Random,Sharpen,ShowProgressBar)
