O.5.1.7 (coupler) Couple to the (offline) ice sheet model BISICLES

[LenkaNovak]

The Climate Modeling Alliance

Software Design Issue 📜

Purpose

We need to couple to an ice sheet model to produce faithful decadal simulations. We will be using the BISICLES model developed at LBNL.

Cost/Benefits/Risks

b: more faithful decadal simulations b: more usable for paleoclimate studies r: this may require a substantial time investment (a good plan should mitigate/prepare for this)

People and Personnel

• Lead: @LenkaNovak
• Reviewers: @juliasloan25

Components

• surface energy balance (SEB) calculation
• surface mass balance (SMB) calculation
• downscaling and regridding
• BISICLES adapter
• topography file import and smoothing

Inputs

• ClimaCoupler adapter infrastructure
• BISICLES code and pipeline
• Julia wrapper around BISICLES (optional)

Results and Deliverables

• [ ] example of using BISICLES using prescribed Atmos fields
• [ ] Buildkite run with a Atmos + Bucket + BISICLES example
• [ ] Buildkite run with a Atmos + Bigleaf + Clima Snow + Clima LSTM Rivers+ BISICLES example

Task Breakdown And Schedule

### Tasks
- [x] decide on template - CESM and CISM
- [ ] design the implementation solution - [Overleaf doc](https://www.overleaf.com/read/gkbmqdfgdqzc) (details to follow at / after AGU)
- [ ] create atmos output file (or at least the pipeline for it)
- [ ] implement SEB
- [ ] implenent SMB
- [ ] downscaling
- [ ] demonstrate forcing BISICLES with ClimaESM output
- [ ] introduce snowless coupled ESM example
- [ ] example adding ClimaESM snow, river and big leaf models

This is exciting, and SDI looks good to me (for now--we can add details as they become clearer).
