Re: [ferret_users] PyFerret/Ferret release v7.4.4

Thank you Ansley,
For providing the update. 

I was wondering that do we (Ferret) have capability to handle station data ? I have asked this question few weeks ago when I was working on a research voyage data of CTD bottle sample and Shipboard CTD along the track of ship. Russ and you also suggested some solutions to get a proper netcdf file for such data but I didn't understand anything.

And one more thing I also want to compute neutral density surface so is there any function available for that ?

Cheers, Saurabh

Hi all

A new PyFerret and Ferret v7.4.4 are available:


The main purpose of this release is to link with netCDF; some datasets and url's cannot be used correctly with the newer netCDF 4.6 library. 

There are also a few bug fixes, including several items reported in the Ferret List.  We'll answer those threads to let you know what was done.

Finally, there's a new default color palette for Ferret.  A number of you have been urging this for a while and we have become convinced.  The new default colormap is "viridis", which is a Perceptually uniform colormap .  I've attached an example plot.

You can always change your color palette in any of these ways:

  • For a single command, with the /PALETTE qualifier:

      SHADE/PALETTE=centered_diff wind_speed

  • For the current session with the PALETTE command: 

       PALETTE rnb2  ! use rnb2 for subsequent commands unless /palette qualifier is used

  • For all your PyFerret or Ferret sessions, by putting a PALETTE command into a .ferret startup file.

And see the FAQ's for more discussion of color palettes.  We'll be adding more there, including examples of some of the nice ones available.
