Description
The function converts the PSD in volume concentration (µL/L, ppm) to number
concentration (particle/L/µm).
Usage
1
lgetpnc(x)
Arguments
x
A lisst object of type 'vol' or 'csa'.
Details
Volume concentration is converted to number concentration by using
the volume of a sphere with radius equal to half the median particle size
for each bin. The number concentration is then the sphere equivalent number
concentration. The absolute magnitute of the PSD will be only approximate if
particles are not spherical, but as long as the particles are not expected to
significantly change shape with size, the slope of the distribution will be
accurate.
