* OR do we need to allow for another level?
* xradar --> sweep 0 --> ref ()
* What should the dimensions of our xarray dataset be?
* (azimuth, range)?
* (gate?)
* For each sweep, have its own dataset
* Joe working on the ldquants PR
* Initial code for PR this week

### :satellite_antenna: State of PyART
* Implemented Github Actions for **some** of the docs build
* Google Analytics Works

### :loudspeaker: Discussion, questions, and updates
* Thoughts on setting up a recurring PyART meeting? Can invite the community to join too!
* Every other week?
* If we don't have anything to discuss, we can always cancel!
* Social Media - Does anoyone else want to help?
* Setting up this as a Team account - link to pyart gmail account
* Weekly updates - keep it more alive
* PyART for different severe weather!

#### Current Issues
* Zach - references/documentation
* Tagged Meteoswiss folks (Jordy)
* Until we get book, see where formula for QPE module
* **Most** functions include the associated reference in the docstring
* Book will be only temporary placeholder
* Testing Data ([#1041](https://github.com/ARM-DOE/pyart/issues/1041))
* Current process
* Download data from https://engineering.arm.gov/~jhelmus/pyart_example_data/
* Move data to proper directories in the examples
* Requires going through last few lines of [`.gitignore`](https://github.com/ARM-DOE/pyart/blob/main/.gitignore) file
* What is the best way of dealing with this?
* One way forward - [pyart-data](https://github.com/mgrover1/pyart-data-demo) package? Module?
* Uses [Pooch](https://www.fatiando.org/pooch/latest/index.html)
* Same strategy used by MetPy, Pythia, etc.
* Data API

            import pyart
            from pyart_data import get_test_data
    
            radar_file = get_test_data('XSW110520105408.RAW7HHF')
            radar = pyart.io.read(radar_file)
            
            ...

* Next steps
* Modify example scripts to use this
* Check to make sure github actions can handle 400+MB files
* Build docs using this approach
* Questions
* Should this be its own package?
* Advantages
* Can be used by other repos (`ACT`, `RadTraQ`, `PyDDA`)
* Could be a more generic `arm-test-data`
* Easier to test on its own
* Consistent with ProjectPythia (later date, if we want to contribute upstream, would be easier)
* Easier to modify the endpoint (`https://engineering.arm.gov/~jhelmus/` for now)
* Disadvantages
* Another package users would need to know
* Not directly packaged with PyART - requires additional download (how we deal with this now still)
* Discussion
* Does this sound doable?
* Put into `pyart.testing` module
* Zach checking to see process of adding new files
* Process of adding new data
* Overhaul CI [#1035](https://github.com/ARM-DOE/pyart/issues/1035)
* Current issues with solving this
* Building docs within CI - [#1041](https://github.com/ARM-DOE/pyart/issues/1041) will help with this
* Questions
* Should we use pre-commit hooks + Black code formatting?
* Used to pre-check code before commiting to repo
* For example if there are flake8 issues, will auto-fix
* Pros
* Do not need to worry about formatting
* Includes auto-fixes - user does not need to go through and make edits manually
* Single, formatting standard
* Cons
* Additional step on setup - `pre-commit install`
* Some [weird formatting decisions with math](https://github.com/psf/black/issues/148)
* Would likely make **numerous** changes to existing code, causing headaches with merging PRs/such
* Should move forward!
#### Additional Discussion -If we have time
* Meetings - every other week
* Zach + Max must attends
* Make them open? For sure!
* [Earthcube meeting](https://www.earthcube.org/2022-earthcube-annual-meeting) in June - abstract due next week
* Zach put abstract for PyART + ACT for SciPy
* Open ARM - Working with ARM data using various tools
* Start working on abstract - Max
* Cookbooks Design Doc - first design review (already scheduled)
* Design review!
* Xradar - Xarray in PyART - week after the cookbooks discussion
* [Design discussion](https://docs.google.com/presentation/d/1xiyvCK6vUcY92R3TCl8REmUT4ejuIzI5QxB9YIAQ1jA/edit?usp=sharing) soon
* Thoughts on Github Discussions?
* Like the MetPy has them setup
* Announcements (releases)
* General (discussions about features)
* Ideas (new feature ideas)
* Q/A - most busy - understand this would replicate the email list
* Good thing about GH Discussions - all in one place
* Show and Tell - place for users to share their cool code
* 
* Open up discussions

### Action Items
* **Setup teams on PyART Twitter Account** (Max + Scott)
* **Put together design review for cookbooks** (Max + Zach)
* **Add an issue with the associated agenda, updates, etc.** (Max)
* **Open up Discussions on PyART** (Max)
* **Schedule recurring meeting for the same time**
