O1.5.4a Prescribe aerosol concentrations

[trontrytel]

The Climate Modeling Alliance

Software Design Issue 📜

Purpose

Prescribe the aerosol concentrations based on RCP 4.5 from CMIP 5. The files are here: https://tntcat.iiasa.ac.at/RcpDb/dsd?Action=htmlpage&page=download

Benefits

• We need aerosol optical properties for radiation. (We also need to code a way to compute optical properties from aerosol concentrations, see SDI)
• We need aerosol precursors for cloud droplet activation and ice nucleation in 2-moment microphysics scheme. (The 2-moment scheme is under development. See SDI and SDI)

Results

Run AMIP simulations with aerosol concentrations read from files.

Tasks for prescribing data from ClimaCoupler (this was abandoned for the solution below)

• [x] Visualize the RCP 4.5 data
• [x] Store the data on Caltech box
• https://github.com/CliMA/ClimaCoupler.jl/pull/506
• ~Convert (lat, lon, p, t) fields to (lat, lon, z, t) fields~
• ~Run spherical simulations with prescribed aerosols (no coupling between aerosol and anything) and test that our output diagnostics reproduce the prescribed files~

Tasks for prescribing data from ClimaAtmos

- [x] [Aerosol prescribing enabled in Atmos](https://github.com/CliMA/ClimaAtmos.jl/pull/2815)
- [ ] [add aerosol optics in rrtmgp](https://github.com/CliMA/RRTMGP.jl/issues/460)
- [ ] use aerosols in from the coupler
