Hello Saurabh,
for those using Seabird CTDs there is a python tool cnv2nc
delivered by Seabird. There is also a fortran tool doing the same.
It depends a little bit on the specific header format used in our
institute, but takes simply all variables coming from the CTD and
puts them into a netcdf file. Since GPS data are in the file
header, the netcdf-file has a full set of coordinates and in
ferret "use" imports all what you need. If you are interested in
the fortran version, please let me know.
Best, Martin

Thank you Pearse,
I do have that format data. So is there any way
to make it gridded data ? Or how to plot these data sets where
all the attributes are as variables.
Hope you doing good Pearse.

Hello Saurabh,
It definitely can handle point
location station data, but I read these data in
differently to gridded data.
I read them in as a .txt or .dat file
in column format using the
set data command. So instead of having a gridded
data with 2+ dimensions on each variable, you read in
all information (variables and dimensions) as 1D
variables.
It gives you something that looks
like:
I J K L
Lat
1600 . . .
Lon
1600 . . .
Dep 1600
. . .
MyVariable 1600
. . .

Subject: Re: [ferret_users] PyFerret/Ferret
release v7.4.4
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 ?
Hi all
A new PyFerret and Ferret v7.4.4 are available:
https://github.com/NOAA-PMEL/PyFerret/releases
https://github.com/NOAA-PMEL/Ferret/releases
The main purpose of this release is to link with
netCDF 4.4.1.1; 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.
