# [Greenline] Warm Bubble Experiment Tasks for Cycle 34

<!-- Add the tag for the current cycle number in the top bar -->

- Shaped by: EXCLAIM team
- Appetite (FTEs, weeks):
- Developers: <!-- Filled in at the betting table unless someone is specifically required here -->

## Problem
<!-- The raw idea, a use case, or something we’ve seen that motivates us to work on this -->

Outline:

- Following WK82 for the initial and boundary conditions.
- Output variables?
- How do we make it a scientific validation? What results do we expect?
- Anymore scientifically interesting ideas for this warm-bubble experiment? Sensitivity tests or just purely performance and technical tests?

Model infrastructure:

- There are things missing to enable running the warm bubble experiment. These are summarized in a table [here](https://hackmd.io/HvHaFPQrRP-8d9UzMA_Gkg?edit).

- Here we can collect descriptions of independent subtasks. All of these should correspond to an entry in the above table, which has priority "High":

- [Distributed tests in CI](https://hackmd.io/O4Fymu1dTxqTZSC8rdiVVw)
- [Finish domain decomposition](https://hackmd.io/3aTBq9-6QbKZrHOtsA-GpA)
- [Tracer Advection in Driver](https://hackmd.io/YwB5wpaARZOo22loClkMUw?both)
- [Least-Squares Coeff](https://hackmd.io/z84FEYwkToCiqNicr3K5jQ)
- [Microphysics in Driver](https://hackmd.io/jW4GEvNQS3mJf6WqwsDx9Q?both)
- [Turbulence granule](https://hackmd.io/eYtacSdFSVisvljBkmbuXg)
- [Turbulence f2py bindings](https://hackmd.io/hOsEsp06TvyssIFOBU1qqw)
- [CI for standalone driver](https://hackmd.io/hhDl0NZqQg-O-zMFWHiLHw)

## Appetite
<!-- Explain how much time we want to spend and how that constrains the solution -->

Full Cycle 34, with XY people, as long as the "Upstreaming Blueline Granule Integration" project is on track. Else, divert resources to that.

## Solution
<!-- The core elements we came up with, presented in a form that’s easy for people to immediately understand -->

## Rabbit holes
<!-- Details about the solution worth calling out to avoid problems -->

## No-gos
<!-- Anything specifically excluded from the concept: functionality or use cases we intentionally aren’t covering to fit the ## appetite or make the problem tractable -->

## Progress
<!-- Don't fill during shaping. This area is for collecting TODOs during building. As first task during building add a preliminary list of coarse-grained tasks for the project and refine them with finer-grained items when it makes sense as you work on them. -->
