ESDS uses several primary platforms for communication. Here is a list of communication platforms and learning resources if you’d like to ve involved in the ESDS community:

NSA Discourse#

Discourse offers a community where users can ask questions and share progress on various projects. It is setup similarly to the Pangeo discourse. You will need to register for an account, but once registered and logged on, be sure to follow the ESDS channel on this platform.

Email List#

If you would like to join the ESDS Email List (Google Group) to be informed of updates about these meetings and question/answer opportunities, we recommend you join the ESDS Google Goup using this link to the ESDS Group page, then click “Join Group.”

Joining the Google Group will automatically send you a Zulip invitation!


Zulip is an asynchronous messaging platform, run in-house at UCAR, which can be used for both private messages and messages seperated by topic. When posting in a specific “channel”, the user must add a topic, which makes it easier to track various conversations and refer back to communications at a later time. Channels include “ESDS”, “dask”, “python-questions”, “python-dev”, “jupyterlab-hub” and more.

Again, we recommend you join the ESDS Google Goup using this link to the ESDS Group page, then click “Join Group.” New members to this Google Group will receive an invitation to join Zulip as well! Alternatively, this Zulip invite link does not expire.

ESDS Github Repository#

This repository and webpage is a space where we can post progress on this initiative, publish blog posts related to various workflows, document “best practices,” in addition to serving as a resource/discussion spot via comments on pages and posts.

ESDS Forum#

Every other Monday from 2-3pm MT, we hold the ESDS Forum in person and over Google Meet, which provides a venue for discussion, coordination and showcasing work in progress. Examples include:

  • Workflow demos

  • Overview of packages and analysis tools

  • Focused discussions on new efforts

  • Feedback on computing and analysis resources This is a great place to discuss progress on your project, and get feedback from the community!

If you are interested in giving a talk or leading a discussion, please fill out this ESDS Forum sign-up spreadsheet. See the ESDS Forum Meeting Notes for an overview of previous discussions.

Analysis Workflow Special Interest Group (AWSIG)#

The AWSIG provides a communication forum for the exchange of ideas and experiences related to the operational aspects of CISL supported analysis resources and services (e.g. Casper, JupyterHub, GLADE, VirtualGL, etc.). This working group complements the more modeling/simulation focused NCAR HPC User Group (NHUG).

The AWSIG Seeks to:

  • Connect the users & providers of CISL’s analysis resources at regular intervals,

  • Provide advice and feedback to CISL on the current state and future delivery of CISL analysis resources and services,

  • Promote the effective use of NCAR computing facilities by sharing experiences,

  • Collaborate to enhance productivity when using CISL resources,

  • Suggest new research and technology directions in scientific computing,

  • Voice user concerns.


The AWSIG will hold ~bi-monthly meetings during the ESDS Forum. The CISL consulting group (CSG) will coordinate meetings with assistance as needed from the ESDS leadership. Meetings will consist of free format discussions, and informational presentations from CISL technical staff and NCAR/UCAR scientific staff.

CSG will rely on both ESDS leadership and the community to propose topics of interest, and even to present emerging tools, best practices, etc. A successful SIG will be driven by interested stakeholders, as well as from the resource providers in CISL. CSG will have items to directly contribute, but also do a lot of listening and then implementing feedback.

Membership & Participation#

The AWSIG is open to all users of NCAR’s HPC resources. Representatives from CISL’s Consulting Group and relevant resource providers will be in attendance. We desire that representatives from each scientific lab attend as well.

Office Hours#

Have a question about Python/data analysis issues? Looking to get feedback on some project? Set up an “office hours” appointment!

Several ESDS members are prepared to answer your Python questions via 1-on-1 appointments. You can now select the ESDS member with the specialization best equiped for your question, find a time that works for you, and generate an appointment. Please also provide how you’d like to meet (in-person or virtual) and a brief description of your question.

If your question is about an error message you are raising in your workflow, help us help you by being ready to provide a copy of your dataset and code so we can reproduce your error. Depending on your question, we may be able to walk you through a solution or send you documentation/resources that address your question. See the Office Hour Notes for a summary of previous sessions.

NOTE: Office hours are designed for NCAR/UCAR staff.

Project Pythia#

Want to learn more about using Python, GitHub, or Jupyter Notebooks for Earth system data science? Project Pythia is a home for Python-centered learning resources that are open-source, community-owned, geoscience-focused, and high-quality. Check out Project Pythia tutorials, examples, and other training materials here. Project Pythia shares several contributors with the ESDS community and is a resource we highly recommend.
