13 March 2020

This file, written by Brian Arbic with help from Conrad Luecke,
summarizes the contents of the datafiles in this repository. The
datafiles contain time series from the current meter archive (CMA)
used in the Journal of Geophysical Research Oceans paper Luecke et
al. 2020. A preprint of this paper is in this directory. The
datafiles are .mat files (Matlab files). The matlab files often
contain more information than was used in the Luecke et al. 2020
paper; here we describe only the Matlab variables that are necessary
to reproduce the Luecke et al. results.

As stated in the paper, the CMA for this paper was created by applying
further QC'ing and selection criteria to the database created by Rob
Scott. A link to the Scott database, and a brief description of the
database, is given at the beginning of Section 2.1 in the Luecke et
al. 2020 paper. Note that start and end times for the CMA records can
be found in the original Scott database but were not saved in the
outputs in this directory.

The file CMA_temperature.mat contains a superset of the CMA temperature
time series records used in the Luecke et al. 2020 paper.

CMA_temperature.mat contains the following variables:

readme: briefly describes the origins of this Matlab file
CMA_Depth_vec: vector of depths (meters), of 3615 time series records
CMA_Lat_vec: vector of latitudes (degrees North), of 3615 time series records
CMA_Lon_vec: vector of longitudes (degrees East), of 3615 time series records
CMA_Temp: cell containing time series of temperature (degrees Celsius) at the 3615 locations
CMA_Temp_increment: Temporal increment (minutes) of the 3615 time series records

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The file CMA_temp_locs.mat contains a structure that gives the
latitudes (degrees North--variable "CMA_temp.lat"), depths
(meters--variable "CMA_temp.dep"), and indices (CMA_temp.index;
relative to the superset in "CMA_temperature.mat" of the 1711
temperature records described in Section 2.1, and plotted in Figure 1,
of Luecke et al. 2020.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The file CMA_velocity.mat contains a superset of the CMA velocity
time series records used in the Luecke et al. 2020 paper.

CMA_velocity.mat contains the following variables:

readme: briefly describes the origins of this Matlab file
CMA_Depth_vec: vector of depths (meters), of 5468 time series records
CMA_Lat_vec: vector of latitudes (degrees North), of 5468 time series records
CMA_Lon_vec: vector of longitudes (degrees East), of 5468 time series records
CMA_U: cell containing time series of U component of velocity (cm/s) at the 5468 locations
CMA_V: cell containing time series of V component of velocity (cm/s) at the 5468 locations
CMA_U_increment: Temporal increment (minutes) of the 5468 time series records

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The file CMA_vel_locs.mat contains a structure that gives the
latitudes (degrees North--variable "CMA_vel.lat"), depths
(meters--variable "CMA_vel.dep"), and indices (CMA_vel.index; relative
to the superset in "CMA_velocity.mat" of the 2102 velocity records
described in Section 2.1, and plotted in Figure 1, of Luecke et
al. 2020.
