Flippin' Chi Solo (FCS) processing code

Matlab prototype: Ken Hughes, April 2022

C firmware implementation: Pavan Vutukur, October 2022

For full details, see

Hughes et al. (2023). A turbulence data reduction scheme for autonomous and expendable profiling floats.
Ocean Sci. 19, 193–207, doi:10.5194/os-19-193-2023

Directory layout:

  • full: The standard processing
  • reduce: The processing using the data reduction scheme
  • reducedC: The processing in C language using the MATLAB data reduction scheme from reduce
  • other: Functions called by both methods
  • comp: Functions used with compressed files
  • sat: Documentation and scripts for parsing and processing .sat files

Dependencies (beyond standard Matlab tools):

Seawater toolbox functions (sw_... .m), copies of which are available at github.com/OceanMixingGroup/chipod_gust/tree/master/software/mix_files. Some versions of the seawater toolbox do not work with vectors and will not work here.

integrate.m from
github.com/OceanMixingGroup/mixingsoftware/blob/master/marlcham/integrate.m

Notes:

Processing FCS data is much like processing Chameleon data; both are vertical microstructure profilers. However, the different sensors and different deployment methods of the two instruments mean that it is worth having a separate and stand-alone processing suite for FCS. Indeed, some functions (e.g., Kraichnan and Nasmyth spectra) already exist in MixingSoftware. I've rewritten them (and included a _fcs in the filename) to keep the directory more self contained.
