Good Evening Sir Hope you are doing well. Can you please help me in knowing how to access CALIPSO data for studying vertical profile of aerosol during dust storm event in India? I generally have to work upon Level 2 Daily Data of CALIPSO 1. Total attenuated backscatter coefficient 2. Vertical Feature Mask 3. Aerosol subtype Also tell me which software (if link & code) will help me to get desired output. I will be grateful to you. Looking forward to hearing from you. I am attaching some research papers for your reference. Regards Rajat Verma Student |

Dear Vijay Ganesh, Sorry for my very late response on this issue. I have now compiled ccplot and its dependencies (basemap) to run natively on Windows, so that there is no need to use the Windows Subsystem for Linux, and the ccplot API also becomes available in the local Anaconda distribution installed for Windows. I have tested this on Windows 10 with Anaconda Python 3.8. The instructions are on the ccplot website (https://ccplot.org/download/) under the section "Windows (native)". Please let me know if you still any problems with the installation. Kind regards, Peter -- Dr. Peter Kuma E-mail: pe...@pe...

Hello I have been trying to install ccplot in windows. I have installed Anaconda with python 3 for windows. As per the "Getting Started" guide, it was recommended to install with Linux subsystem for windows. I have done correctly upto this part. After this while trying to follow the "Installing in Linux with Anaconda". I'm getting into issues. Can you provide a bit more detailed guide?. The Ubuntu app couldn't detect my python/Anaconda which was installed for windows. |

Dear Ankan, I think the problem is with the command line arguments. Instead of: ccplot -o calipso1.png cmap/calipso-backscatter.cmap calipso532-layer /HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf the command should be: ccplot -o calipso1.png -c calipso-backscatter.cmap -x 0..500 calipso532-layer /HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf Note the missing "-c", and also "cmap/calipso-backscatter.cmap" should probably be "calipso-backscatter.cmap". "-x 0..200" may be needed to select a smaller region - the image size would be too large for the plotting library to make. Can you try that? Kind regards, Peter -- Dr. Peter Kuma E-mail: pe...@pe...

Dear Sir/Madam,
I have installed ccplot in Ubuntu 18.04 LTS app
on my PC (Windows 10). For the installation process, I followed the user
guide which is available on the website (https://ccplot.org/download/). The
steps I followed for the installation processes are given below:
1. To install the required libraries and ccplot:
sudo apt install --no-install-recommends python3 python3-dev gcc
python3-distutils cython3 libhdf4-dev libhdfeos-dev python3-pil
python3-numpy python3-matplotlib python3-mpltoolkits.basemap
ttf-bitstream-vera
2.Build and install ccplot:
tar xzf ccplot-1.5.6.tar.gz
cd ccplot-1.5.6 sudo python3 setup.py install
After that to check the version I simply run the 'ccplot -V' command to
print the version of the ccplot and the output came is in the following:
ccplot 1.5.6
Third-party libraries:
matplotlib 2.1.1
basemap 1.1.0
Copyright (c) 2009-2015 Peter Kuma.
This software is provided under the terms of a 2-clause BSD licence.
Now after that I wanted to make a plot from a hdf file of CALIPSO data
using ccplot as per the instruction given in the Chapter 6 of 'Visualising
Data from CloudSat and CALIPSO Satellites'. I have made a directory named
'HDF' inside the folder 'ccplot-1.5.6.' where I put the hdf files I want to
plot.
1. First I gave the command to know the information about the file
ccplot -i
HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf
and the output came
Type: CALIPSO
Subtype: profile
Time: 2006-06-13 07:44:32, 2006-06-13 07:47:00
Height: -1815m, 39855m
nray: 200
nbin: 583
Longitude: 84.06E, 86.27E
Latitude: 21.55N, 30.46N
So up to this step, I think this is working fine. But when I want to plot
and give the command below it throws an error!
ccplot -o calipso1.png cmap/calipso-backscatter.cmap calipso532-layer
/HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf
ccplot: calipso532-layer: HDF: SDstart failed: b'Bad file name on open'.
Does it mean ccplot is not installed properly? Can anyone tell me why this
is happening? And how to solve this problem? I am very new to this software
tool and any help on this is very much appreciable. Thank you.

I am attaching the sample file and also the lines that came during the

not. Please find the attachment. Thank you.

Hi Suqian, The libhdf4 and libhdfeos2 libraries should be installed from the Linux distribution repositories (not conda). If you use a Debian-derived distribution (e.g. Ubuntu), use this apt install command: sudo apt install --no-install-recommends python3 python3-dev gcc python3-distutils cython3 libhdf4-dev libhdfeos-dev python3-pil python3-numpy python3-matplotlib python3-mpltoolkits.basemap ttf-bitstream-vera The installation instructions on the website are for native Python installed from Linux distribution repositories. Installation under conda would require some other steps not described on the website: - Install git and libgeos, on Debian or Ubuntu with: apt install git libgeos-dev - Install basemap from their GitHub repository. Installing basemap with `conda install` does not work because the package appears to be out of date. pip3 install git+https://github.com/matplotlib/basemap.git - Install ccplot under conda (without using `sudo`): python3 setup.py install I have tested this on Ubuntu 21.04 with the latest Anaconda 3. What Linux distribution are you using? Kind regards, Peter -- Dr. Peter Kuma E-mail: pe...@pe...

Hello, I'm trying to use ccplot to plot the backscatter profiles from CALIPSO data, but I'm having difficulties doing so. An example of an HDF file I need to use is: *CAL_LID_L2_VFM-Standard-V4-20.**2006-06-13T04-54-47ZN.hdf* And to run the code I write on the (Linux) terminal: *ccplot -o calipso.pdf -x 0..1000 -c /usr/local/share/ccplot/cmap/calipso-backscatter.cmap calipso532-layer CAL_LID_L2_VFM-Standard-V4-20.2006-06-13T04-54-47ZN.hdf* But I receive the following message: *ccplot: Field "b'Integrated_Attenuated_Backscatter_532'" not found* Can you help me, please? Thank you very much -- Ben-hur Martins Portella |

Dear Sanaz, Sorry for my late response. I am particularly busy right now working on multiple projects. I think the problem with your installation on Windows might be that Anaconda has recently phased out Python 2.7 packages, and I assume you might have installed a Python 3 version. I have changed the link in the ccplot documentation to point to the Anaconda Archive: https://repo.anaconda.com/archive/ which still has Python 2.7 32-bit packages for Windows. The latest one appears to be "Anaconda2-2019.10-Windows-x86.exe". Can you please try this one? I have very recently ported ccplot to Python 3 on Linux, but will have to compile the HDF libries on Windows to get it working there. Alternatively, if you have access to a Linux computer or a Linux virtual machine, I suggest that you try ccplot there (with ccplot version >= 1.5.4). Kind regards, Peter Kuma ---- To whom it may concern, Since I haven't received any response since 11 days ago, I emailed again and ask my question: {This is Sanaz, assistant professor, who works with CALIPSO data. I want to use ccplot and I have problems. I tried to install it on windows based on ( https://ccplot.org/download/) and it seems that there is a problem. I attached the problems. I was wondering if someone can help me to fix it.} I appreciate that, Thanks, Sanaz |

Dear ccplot developer. Hello, I'm KangHo Bae who is a graduate student in the master's degree course. I want to install ccplot in the Linux server without the root authorization. But I can't find the method in the document. So I wonder that is there any method to install ccplot by Linux anaconda. Also, If there any sample code for plotting CALIPSO L1B Total_Attenuated_Backscatter_532 in location(lat, lon)-altitude, could you introduce to me? Best regards, KangHo Bae |

I have updated the website to make it less confusing. The installation steps are: 1. Install Anaconda 32-bit (Python 2.7 version) https://www.anaconda.com/download/. Note: Anaconda 64-bit or Python 3 won’t work. 2. Install the basemap package in the Anaconda Prompt: conda install basemap 3. Install ccplot using the supplied Windows installer. You should be able to run ccplot in the Anaconda Prompt: ccplot -V Both 32-bit and 64-bit Windows 10 should work fine, providing you install Anaconda 32-bit / Python 2.7. Let me know if you have any more questions. Best regards, Peter |

Dear madam/sir, I would like to explore calipso's data; therefore, I would like to install ccplot. In this regard, I could installed the following software: * python 2.7.14, basemap-0.99.4.win32-py2.5.exe * Microsoft Visual C++2010 * HDF-4.2.13-win32.msi * Anaconda2-5.0.1-Windows-x86.exe * ccplot-1.5.2.win32-py2.7.exe I tried to download the other requirements, mentioned at your website, but I got baffled. I could not find appropriate software or which files should I download because there were a lot of files which made me confused what I should do with them. I, also, could not understand what I should do with "hdfeos2_19" after getting from the Net since there were no *.exe file in it. Could you please help me how I can install other requirements?

Hi Peter! Thank you so much for your answer! It really helped me! I read the Quality Statements several times, but it wasn't so clear to me how to really read it! Thanks a million! Cheers Thaize ________________________________ De: Peter Kuma <pet...@fa...> Enviado: quinta-feira, 23 de novembro de 2017 13:51:13 Para: BARONI, THAIZE; ccp...@li... Assunto: Re: CALIPSO L2 data - Help Hi Thaize, Great to hear you find ccplot useful. The rows and columns of Integrated_Attenuated_Backscatter_532 in the layer product mean profile number and layer number, i.e. there can be up to e.g. 10 layers detected in each individual vertical profile. The actual number of identified layers is stored in Number_Layers_Found (the remaining layers are filled with -9999.0. Latitude and Longitude contain 3 values per profile in the 5 km products: 1) latitude/longitude the first pulse included in the 15 shot average 2) the footprint latitude/longitude at the temporal midpoint (i.e., at the 8th of 15 consecutive laser shots) 3) the footprint latitude/longitude for the final pulse See CALIPSO Quality Statements Lidar Level 2 Cloud and Aerosol Layer Products, page 3 (https://eosweb.larc.nasa.gov/PRODOCS/calipso/Quality_Summaries/CALIOP_L2LayerProducts_3.01.html). Layer_Base_Altitude and Layer_Top_Altitude contain layer base and top altitude corresponding to layers in Integrated_Attenuated_Backscatter_532 (by column). I hope this answers your question. Good luck with your analysis! Let me know if you have any more questions.

Hi Thaize, Great to hear you find ccplot useful. The rows and columns of Integrated_Attenuated_Backscatter_532 in the layer product mean profile number and layer number, i.e. there can be up to e.g. 10 layers detected in each individual vertical profile. The actual number of identified layers is stored in Number_Layers_Found (the remaining layers are filled with -9999.0. Latitude and Longitude contain 3 values per profile in the 5 km products: 1) latitude/longitude the first pulse included in the 15 shot average 2) the footprint latitude/longitude at the temporal midpoint (i.e., at the 8th of 15 consecutive laser shots) 3) the footprint latitude/longitude for the final pulse See CALIPSO Quality Statements Lidar Level 2 Cloud and Aerosol Layer Products, page 3 (https://eosweb.larc.nasa.gov/PRODOCS/calipso/Quality_Summaries/CALIOP_L2LayerProducts_3.01.html). Layer_Base_Altitude and Layer_Top_Altitude contain layer base and top altitude corresponding to layers in Integrated_Attenuated_Backscatter_532 (by column). I hope this answers your question. Good luck with your analysis! Let me know if you have any more questions.

Hello there! My name is Thaize and I'm a PhD student from NUIG, Ireland I'm part of the C-CAPS group and currently, I'm working with CALIPSO data I found ccplot and used it at the very beginning of my PhD... it was really useful! However now, I have to do some plots on my own and I'm kind of stuck I don't really have any question about ccplot, but about CALIPSO data itself (L2 especially) Could you help me, please? I don't know very well how to read and interpret CALIOP L2 Integrated Attenuated Backscatter data...I mean, the data itself (the rows and columns) I read the CALIPSO documentation several times but I still don't understand how it works...Could you please explain it to me? The dimensions (number of columns and rows) between lat/lon, Integrated Attenuated Backscatter 532/1064 and Altitude, for example, are different and I don't get why This doesn't happen with L1 and L1.5 data... I'm sorry if this is a basic question and it's not directly related with ccplot, but as I said, I'm struggling with it for ages now. I'd really appreciate any help or explanation you could provide! Thank you very much for your attention Cheers Thaize |

I want to know this program x1 and x2 is based on CAL_LID_L1-Standard-V4-10.2011-04-02T06-14-50ZD data in the Profile_UTC_Time to choose it? So my Profile_UTC_Time document I do not know how to correspond to your program x1 and x2?
x1 election is 0, the time is from 06:00 onwards?
Profile_UTC_Time data range is 0 to 63449, why I x1 choose 0, x2 choose 63449, the results obtained, the time range is 06:14 to 07:07? Why is that? How to use this time range in your program? please help me

Dear sir or lady,
This is Zhenwei Shi from Peking University. Glad to contact with you.
I used ccplot in Mac OS. Ccplot is very easy to draw LiDAR L1 Products. But I do not know how to use ccplot plot pictures of LiDAR L2 Cloud Layer Products. Can you give me a few examples about using ccplot to plot LiDAR L2 Cloud Layer Products?
Sincerely yours,
Zhenwei Shi.

Are you sure you are using the Python.exe provided by Anaconda? It might be that you have two Python installations, and the correct one to use is located in a folder like *C:\Anaconda\Bin\Python.exe* P.S. the VOCAL software suite was just released by NASA-DEVELOP, which is a tool for visualizing L1 data. You may find it useful in your research so i'll leave the link here: https://github.com/NASA-DEVELOP/VOCAL/releases Thanks, Grant Mercer On Tue, May 9, 2017 at 2:26 AM Wi Wu <51w...@gm...> wrote: > Dear Sirs/Madam: > > > > > > I am a graduate students in Sun Yat-sen University in China.

Hi Wu Yi, I think you might have two different versions of Python installed - one under C:\Python, and the other one is Anaconda. The package mpl_toolkits is installed under Anaconda, while ccplot is under C:\Python. The easiest solution would be to uninstall C:\Python and keep only Anaconda (if you don't need C:\Python for anything else). You will need to reinstall ccplot afterwards. You don't have to cite my thesis, only if you want to. Thanks for reporting the problem - if it still doesn't work let me know, it might be that something is wrong with the ccplot installer.

Dear Sirs/Madam:
I am a graduate students in Sun Yat-sen University in China. Recently I am trying to read CALIPSO L1 data, and I found your tools, but when I install it, there is an error:
C:\Python>ccplot -V
Traceback (most recent call last):
File "C:\Python\Scripts\/ccplot", line 53, in <module>
from mpl_toolkits import basemap
ImportError: cannot import name basemap
I already install every stuff as your website says, first install Anacoda, then conda install basemap, so I don’t know why it won’t work, I will be really appreciated if you could help me or even just gave me some useful information!
P.S.
I am fully aware that I must cite your paper after using your tools!
Regards,
Wu Yi

Thanks very much for your reply. I found the python in Anaconda2-4.3.0.1 was 2.7.13 version. I downloaded https://repo.continuum.io/archive/.winzip/Anaconda2-4.3.0-Windows-x86. and have installed successfully.
