Re: [ferret_users] txt files

Hi Guilia,
Yes you can work with data from text files and netcdf files together.  
To find out how to read text files, look at topics under "ascii data" in 
the Users Guide.  Once you have opened  more than one data set, you  
specify variables from each one with the data set number. You might want 
to look through the first 2 chapters of the Users guide to get an idea 
of the commands you will need.  If you are a new user, I suggest you 
scan through chapters 1 - 4 and 6 for an overview of Ferret commands.

There is a script called compass_rose.jnl which makes an image that 
shows compass directions as attached below.  If you are thinking of a 
wind rose which summarizes wind speed and direction 
(http://www.wcc.nrcs.usda.gov/climate/windrose.html) then this script  
addresses that. Read the script to see how it's divided into different 
sections, exploring how to do this in Ferret.
