Dear Zhang,

I am not sure what the problem might be. Are you sure you have
downloaded the correct version of Anaconda? It should be the following:

https://repo.continuum.io/archive/Anaconda2-4.3.0.1-Windows-x86.exe

I have tried uninstalling Anaconda on my Windows and installing the
latest version above, and the ccplot installer did work for me, although
that was on Windows 10. During the installation I selected "Install for:
Just Me", "Add Anaconda to my PATH environment variable" and "Register
Anaconda as my default Python 2.7". Do you have a computer with Windows
10 where you could try the installation?

Regards,

Peter

Install ccplot

[ZHANG X. <zha...@la...>]

Dear sir:

I tried to install ccplot on windows7. I have installed the Anaconda 32-bit (Python 2.7 version) and the basemap successfully. But when I installed ccplot with the windows installer, it showd python2.7 cloudn't be found. I have checked the Python2.7 runs well. Cloud you point out the possible problem?

Re: ccplot installation

[Peter K. <pet...@fa...>]

Hi Piyushkumar,

Sorry for the late response. It seems that python(x,y) is no longer
actively maintained, and Anaconda is now a better choice for a Python
distribution on Windows. I suggest you install 32-bit Anaconda (Python
2.7 version):

https://www.continuum.io/downloads

(64-bit Anaconda is not compatible with ccplot, and 32-bit Anaconda
works on 64-bit Windows just fine.)

After that, install basemap in the Windows Command Prompt:

conda install basemap

Finally, install ccplot using the Windows installer provided on the
ccplot.org website.

You should be able to run ccplot in the Command Prompt:

ccplot -V

Let me know if you still have any problems with the installation.

Best regards,

Peter

[Piyushkumar P. <piy...@gm...>]

Dear sir,

I am a new user of CALIPSO and CloudSat data sets.
I come across to ccplot software, which I am trying to install on windows
64-bit machine, but it unable to detect python 2.7 path. Though python 2.7
is already installed on my machine. Even I am not able to write a path of
python installation directory when it asked to write.

please help me to install ccplot on a 64-bit windows machine.

Re: ccplot error

[Grant M. <gme...@gm...>]

it looks like the package *libhdf4-dev* is not being found. Can you paste
where the installation of this is? Head over to the terminal and type *dpkg
-L libhdf4-dev*

If the package is not installed, install it and attempt to run again.
However there is a possibility you have the package installed, but the
setup.py list is not exhaustive and won't find it. In that case if you
email back where the package files are located I can help you point
setup.py to that location.

Hi Conrado,

The missing `hntdefs.h` file is from the libhdf4 library. Can you make
sure it is installed on your system?

What operating system are you using?

Re: Trouble with ccplot installation

[Grant M. <gme...@gm...>]

For the error you're receiving on windows, it looks like you first need to
install wheel <https://pypi.python.org/pypi/wheel>. Can you also reply with
the version of python you are using? you can check your version with *python
-v . *The version is important as ccplot does not support support python
3.x and later versions.

I'm taking a guess it's the version of python being used causing the error
because of this line in the output:

ccplot\hdf.pyx:272:31: Comparisons between bytes/unicode and str are
not portable to Python 3


seem's you're attempting to use Python 3 to build a python 2.7 and below
library.

--------------------------------------------------------

As for linux, it looks like the package *libhdf4-dev* is not being found.
Can you paste where the installation of this is? Head over to the terminal
and type *dpkg -L libhdf4-dev*

If the package is not installed, install it and attempt to run again.
However there is a possibility you have the package installed, but the
setup.py list is not exhaustive and won't find it. In that case if you post
where the package files are located I can help you point setup.py to that
location.

Trouble with ccplot installation

[Raghavendra S. M. <rag...@gm...>]

Hi there!

I am having some trouble installing ccplot on our HPC (os is linux)
and on my windows7 laptop too (I have conda python).
When I try pip install ccplot.. I have the following error (attached
as txt files..)..
Could you tell me how to get ccplot installed.. I would be happy if I
can get it installed on either of the machines..

Raghu

Hi,

I'm having difficulty building ccplot 1.5 on Ubuntu 14.04, the issue is
parallel to this
<https://sourceforge.net/p/ccplot/mailman/ccplot-general/thread/54E...@ip.../>

triple checked all of my dependencies, and follow the instructions on the
site to the tooth up until this line:

Hi Andrew,

At the moment ccplot performs nearest-neighbor interpolation, which
means every value displayed in the plot is an actual value from the
data. The NASA browse images likely use some sort of averaging, but I'm
not sure what the exact algorithm is.

The ccplot API (http://ccplot.org/api/) provides a function
ccplot.algorithms.interp2d_12 which does averaging when zooming out, and
nearest-neighbor interpolation when zooming in. In my experience, the
results of this interpolation are closer to the NASA produced images. I
would like ccplot to switch to the new algorithm in future. Since you
asked, I have done the modification in the latest revision, available
from github:

https://github.com/peterkuma/ccplot/archive/master.zip

You can try it out, but I can't guarantee it gives good results in all
situations, as I haven't done much testing. If you use Windows, I will
prepare a build for you (the code from github needs to be compiled).

Attached is a plot produced with the new algorithm. It is still not as
clear as the original, though. Tuning the colormap might help a little.
It was produced with the command:

ccplot -o calipso532.png -d 80 -c calipso-backscatter.cmap -a 90 -x
4:09:13..4:22:42 -y ..30000 calipso532
CAL_LID_L1-ValStage1-V3-01.2007-06-12T03-42-18ZN.hdf

Regards,

Peter

ccplot profile vs. CALIOP browse image profiles

[Andrew P. <and...@mo...>]

Hi,

Thank you for creating such a wonderful piece of software and for keeping all of the code open source!

I’ve been trying to generate CALIOP profiles that best match the NASA browse image accessible here: http://www-calipso.larc.nasa.gov/products/lidar/browse_images/production/ <http://www-calipso.larc.nasa.gov/products/lidar/browse_images/production/>

ccplot has come the closest! However, as with my own script, there is a lot of “noise” from ~ 0–8.2 km, that is not apparent in the NASA browse images.

Is there a way to overcome this?  Have the NASA browse images had some sort of smoothing or masking applied?  If so, is there any documentation on this?

I’ve attached some figures to demonstrate the problem.  While ccplot does a good job representing large profiles, there is generally too much noise to identify cloud/aerosol signals located within small latitude ranges and at low altitudes (0–8.2 km).

Kind Regards,

Andrew

Dear Luka,

Sorry I haven't replied to you sooner. The problem you describe is
likely because of missing hdfeos library. Can you make sure the package
is installed? Use this command to install all required packages:

sudo apt-get install --no-install-recommends cython libhdf4-dev
libhdfeos-dev python-imaging python-numpy python-matplotlib
python-mpltoolkits.basemap ttf-bitstream-vera

But I haven't tested with Ubuntu 14.04 specifically, so it might as well
be a different problem.

Regards,

Peter

Hi Heather,

Sorry this was a bug in ccplot. If the vertical extent was not specified
explicitly by -y, nothing would be plotted. It has been reported to me
recently, but I fixed it just now. Please use the new release ccplot
1.5, which is now available on the ccplot web site. Also fixed is a
problem with colormap search path on Windows, so using "-c
cloudsat-reflectivity.cmap" should be enough. I hope there won't be any
more issues, but please let me know if encounter any.

Regards,

Peter

ccplot only plotting colorbar

[Cronk,Heather <Hea...@co...>]

Hi,
I'm new to ccplot and am currently just trying to reproduce something similar to the plots in the provided documentation. I have attached the plot that is created from the following command:

ccplot -o cloudsat2.pdf -x 0..1000 -c ../cmap/cloudsat-reflectivity.cmap cloudsat-reflec ../../../data/2013257190147_39272_CS_2B-GEOPROF_GRANULE_P_R04_E06.hdf

As you can see, it seems to be cutting off the plot and only showing the colorbar and part of the title. Do I need to adjust the aspect ratio or something else to see the whole plot?

Thanks,
Heather

Dear Trismono,

Thank you very much for reporting the problem. This is a bug in ccplot.
When the vertical extent (-y) is not specified, nothing would be
plotted. I fixed the problem in the latest revision on github, but
please specify the -y option explicitly while I prepare a new Windows
release.

Regards,

Peter

because you are compiling ccplot in a directory which contains unicode
characters in its path.

The bug has already been reported to cython, but they don't seem to have
done anything about it.

https://groups.google.com/forum/#!searchin/cython-users/unicodedecodeerror/cython-users/D8_mhkAUZXA/0ALSNrC7iMkJ

I suggest you try moving the ccplot directory to a different system
path, one which does not contain non-ASCII characters. If it does not
help, please let me know.

Regards,

Peter

Hi Hamed,

It is a bit strange your file is 2014-06-13 22:05:53 - 22:12:07, I could
only find CAL_LID_L1-ValStage1-V3-30.2014-06-13T22-02-33ZN.hdf, which is
22:02:33 - 22:49:00. But anyway...

To make a basic plot use a command like this:

ccplot -o 1.pdf -x +0:00..+3:30 -c calipso-backscatter.cmap calipso532 1.hdf

The two most important things you want to tune are:

- The subset you want to plot with the `-x` option (here subset between
0min and 3min 30s relative to start). Supported format for `-x` is in
the manual page[1].

- The dataset (here `calipso532` - "CALIPSO L1B Total Attenuated
Backscatter 532nm") and the right colormap (here
`calipso-backscatter.cmap`). A list of datasets is in the manual
page[1], and a list of colormaps is on page 56 of [2].

Please try to follow the tutorial in Chapter 6 of Visualising Data from
CloudSat and CALIPSO Satellites.

Note that you don't have to enter the full path to a colormap as in the
examples, i.e. use `-c cloudsat-reflectivity.cmap` instead of `-c
/usr/share/ccplot/cmap/cloudsat-reflectivity.cmap` (this would not work
on Windows).

2:
https://github.com/peterkuma/ccplot/blob/gh-pages/pub/doc/pdf/Visualising_Data_from_CloudSat_and_CALIPSO_Satellites.pdf?raw=true

If you still have any problems after reading the tutorial, feel free to ask.

Good luck!

Regards,

Peter

Re:

[Peter K. <pet...@wa...>]

Hi Hamed,

You can put the file in any directory. As ccplot is a console program,
you have to use the Windows Command Prompt to execute it.

1. Open Command Prompt (Start Menu->Run..., type "cmd").

2. Go to the directory containing the CAL_LID_...hdf file. E.g. if you
saved it in C:\calipso, type:

cd C:\calipso

You can determine the path to the directory from the address bar in the
Windows file explorer.

3. Run ccplot:

ccplot -i CAL_LID_L1-ValStage1-V3-01.2007-06-12T03-42-18ZN.hdf

Some information about the file should be printed on the console. You
can run any ccplot commands like the one above. Any plots will be saved
in the same directory.

If you instead get an error such as "ccplot is not recognized as an
internal or external command", it means it is not installed properly or
something else is wrong. Please let me know if that is the case.

Here is a short tutorial I could find on how to open the Command Prompt
and use the cd command to change directories. I hope it helps.

Hi

I used ccplot on windows XP.

I downloaded "CAL_LID_L1-ValStage1-V3-01.2007-06-12T03-42-18ZN.hdf"
So which directory I should put the data to read by ccplot


Thank you

Hi Andrew,

When building on Windows, you should make sure you have the HDF4 and
HDFEOS2 libraries installed. Right now the paths to the libraries are
hard-coded in setup.py to:

C:\Program Files (x86)\HDF_Group\HDF\4.2.9
C:\Program Files (x86)\hdfeos2.18

If you use different versions, just update the paths in setup.py. I
think you need the "static" win32 version of HDF4.

The windows build on the ccplot.org website was made with Visual C++
2008 Express Edition. If I remember right, it was because python2.7
itself is compiled with this version of VS, so it was necessary.

ccplot can be built with the command:

python setup.py bdist_wininst

If everything goes well, it produces the installer executable in dist.

If it doesn't work for you, please let me know, I have to try myself, as
it has been a long time since I was making the build.

Good luck!

Peter
