Syntax

[data,lat,lon] = woa_simple_plot(variable,time,region,depth)

Description

[data,lat,lon] = woa_simple_plot(variable,time,region,depth) plots the nearest available depth-level to depth. variable specifies the parameter to be plotted and region is the rectangular region to be plotted. timespecifies monthly or annual climatology; time='00' for annual climatology and '01' '10' etc. for monthly climatology. The function builds the url, extracting the maximum resolution available (typically 0.25-deg or 1.00-degree grid). data, lat, and lon from the plotted layer are available outputs.

Available variables are:

'temperature' (degrees Celsius)
'salinity' (psu)
'oxygen' (umol/kg)
'o2sat' (%)

'AOU' (umol/kg)
'silicate' (umol/kg)
'phosphate' (umol/kg)
'nitrate' (umol/kg)

time is a string or character array. '00' is annual climatology, while other codes e.g. '02' (February) or '11' (November) indicate monthly climatology.

variable is a string or character array and is the name of the parameter to be plotted.

depth is (a single, double, integer) indicates negative meters below the surface.

region is a vector containing the bounds [S N W E] of the region to be plotted, -180/180 or 0/360 longtitude format is fine. Limits may cross the dateline e.g. [35 45 170 -130].

data, lon, and lat are double arrays containing the plotted data layer. As such, this function can be used to extract data layers from World Ocean Atlas 2018.

Example 1

% Setup nctoolbox:

setup_nctoolbox

% Plot surface nitrate:

variable = 'nitrate';
time = '03';
region = [-5.0, 45.0 ,-120, -150]; 
depth = -0; 
woa_simple_plot(variable,time,region,depth)
