Python wrapper for the JHU Turbulence Database Cluster library. More information can be found at

Use pyJHTDB through SciServer (RECOMMENDED)

The SciServer is a cloud-based data-driven cluster, of The Institute for Data Intensive Engineering and Science (IDIES) at Johns Hopkins University. Users get the advantages of more reliable and faster data access since the SciServer is directly connected to JHTDB through a 10 Gigabit ethernet connection. SciServer provides docker containers with the pyJHTDB library pre-installed.

To use pyJHTDB through Sciserver:

Login to [SciServer]( (may need to create a new account first).
Click on *Compute* and then *Create container* (You could also run jobs in batch mode, by selecting Compute Jobs).
Type in *Container name*, select *JH Turbulence DB* in *Compute Image* and then click on *Create*.
Click on the container you just created, then you could start using pyJHTDB with Python or IPython Notebook.

Please go to SciServer for more information on SciServer as well as the help on Sciserver.

Use pyJHTDB on local computers

Prerequisites: numpy>=1.15.0, scipy>=1.1.0, sympy>=1.2, h5py>=2.8.0, matplotlib>=3.0.0, More prerequisites since 01/08/2021: wurlitzer>=2.0.2

Installing pypi version (Linux and MacOS)

If you have pip, you can simply do this:

pip install pyJHTDB

If you're running unix (i.e. some MacOS or GNU/Linux variant), you will probably need to have a sudo in front of the pip command. If you don't have pip on your system, it is quite easy to get it following the instructions at

Installing from source (Linux and MacOS)

git clone
cd pyJHTDB
pip install --upgrade ./

In Windows

We notice the compilation error in Windows, and provide a temperary workaround in examples\Use_JHTDB_in_windows.ipynb. This method use zeep package. Should be as convient as pyJHTDB.

Basic usage

On first contact with this library, we recommend that you first run test_plain. To be more specific:

from pyJHTDB import test_plain

The code that is executed can be found in pyJHTDB/, and it's the simplest example of how to access the turbulence database.


While our service is open to anyone, we would like to keep track of who is using the service, and how. To this end, we would like each user or site to obtain an authorization token from us:

For simple experimentation, the default token included in the package should be valid.
