Description: 

Particulate backscattering coefficient bbp (700nm); Acquired with WET Labs MCOMS Scattering Meter with 700-nm wavelength and in-water centroid angle of 150 deg. See Table 3 in paper.

The particulate volume scattering coefficient vp was calculated as

vp(150 deg,700 nm) [m-1 sr-1] = Scale Factor * (Output - Dark Counts)

using a factory-determined scale factor and a dark offset, computed separately for each sensor as the mean of the deep-water minima measured during all profiles between July and September 2013 at BATS (https://www.bco-dmo.org/dataset/728371). Particulate backscattering coefficient, bbp(l) [m-1], is estimated as

bbp = 2pchvp(150 deg)

ch = 1.13 for 150 deg (from Boss and Pegau 2001).
