First, welcome to Ferret. You may find that some of the demo scripts will help you as you get started learning Ferret. Follow the "tutorials" link on the Ferret Documentation web page.
For your specific questions, some quick answers:
Are your data in a NetCDF file? If so, then if you have opened your dataset, perhaps it looks something like this.
yes? use my_data.ncThe commands below show a vertical profile, vertical section and t-s plot; where of course you will choose the locations and time ranges that are correct for your dataset.
To make a vertical profile of temperature,
yes? plot/x=300/y=20/L=1 tempor perhaps
yes? plot/x=45w/y=15s/t="15-jan-2002" tempTo make a vertical section at fixed latitude,
yes? plot/y=20s/t="15-jan-2002" tempAnd last, you may have something different in mind for a T-S plot, but here is a way to show temperature as a function of salinity. The command PLOT/VS makes a plot where two variables are plotted as symbols, one on the vertical and the other on the horizontal axis. So define new variables that make TEMP and SALT into simple lists of data. I will choose subsets of the data, just to show how that goes. The \ character is a line-continuation mark; to put a long command on two lines for easier reading.
yes? let/units="deg C"/title="temperature" temp_pts = \
