ADCP_mooring_data_processing

Program for processing ADCP mooring data

Installation

Prerequisite

ADCP_mooring_data_processing need a version of Matlab >= R2006b. The most recent version tested are R2022b (Windows) and R2022b (Linux)

Cloning ADCP_mooring_data_processing repository

Clone the repository:

git clone https://forge.ird.fr/US191/adcp_mooring_data_processing.git

or getting the last zip archive:

https://forge.ird.fr/us191/adcp_mooring_data_processing/-/archive/master/adcp_mooring_data_processing-master.zip

Quick start

Open template_get_adcp_data.m

Input parameters specific to the mooring:

• Raw file location (file with .000 extension)

• Output directory

• Cruise name

• Mooring name (ex: '0-10W')

• Mooring longitude and latitude ([deg-min])

• Clock drift

• Adcp serial number (ex: 15258)

• Adcp type (ex: '150 khz Quartermaster')

• Adcp direction (ex: 'up') % upward-looking 'up', downward-looking 'dn'

• Adcp depth (ex: 150) % nominal instrument depth

• Adcp number if more than 1 Adcp

Processing steps

• Data reading
• Correct clock drift (linear drift)
• Determine first and last indices when instrument was at depth
• Correction of magnetic deviation
• Percent good threshold
• Remove bad attitude (pitch-roll) data
• Calculate depth of each bin
• Depth correction from surface reflection (if ADCP is upward-looking)
• Remove "shadow zone" data (if ADCP is upward-looking)
• Grid data on a regular vertical grid
• Temporal interpolation to fill gaps
• Remove tide effect
• Interpolate data on a regular temporal grid (6hour)
• Save data as netcdf (version 1)
