MISC Lab Toolbox

Matlab tools for oceanographic analysis focusing on the inherent optical properties (IOPs) of the open ocean.

Features

The functions available are:

• compute_bbp.m: Compute the particulate backscattering b_bp from the backscattering bb
• correct_npq.m: Correct for non photochemical quenching using Xing et al. (2012) and/or Sackmann et al. (2008)
• etimate_mld.m: Estimate the mixed layer depth (MLD) with one of the following method: fixed temperature threshold, fixed density threshold, variable density threshold or fixed density gradient.
• meshprofile.m: Interpolate data between profile (often used with scatter3m)
• need_npqc.m: Determine if need a non photochemical quenching correction
• scatter3m.m: 4D visualization with earth map (latitude, longitude, depth and measure)

Requirements

To work properly the toolbox need those features in matlab path (addpath):

• betasw_ZHH2009.m from Xiaodong Zhang available here
• gsw_matlab_v3_04 from TEOS-10 available here
• lr2.m a robust linear regression type II, can substitute it by regress() instead
