Stephen Price will lead this discussion with help from Ruby Leung, Jon Wolfe, and Jeremy Fyke (Unlicensed)
Charge to attendees:
- are there opportunities on our current science problems there are being neglected?
- water cycle
- biogeochemistry
- ocean-cryosphere
- what science problems exist that we should be looking at that we are not looking at?
- tropical cyclones
- electrification
- where are we subcritical?
- feel free to flesh out things that Phil brought up during the main atm session
...
- pressure gradient term
- sub-column treatment for radiation (convective/stratiform partitioning)
...
- deep dive for v2 data structures and will intersect w the CMDV software project (Ghan, Goldhaber, Salinger, Taylor, Atm GLs)
- Surface coupling
...
- Prognostic aerosol surface area
- Modify MAM aerosols to allow stratospheric aerosols
- Gas/Particle partitioning (MOSAIC) & Nitrate
- SOA
- Brown Carbon
- Speciated Dust
...
- in-situ diagnostics (diurnal cycles, PDFs, etc, c.f. Katherine Calvin (Unlicensed), Po-Lun Ma, Steve Goldhaber (Unlicensed) conversations)
- easy to create and use data models
- ?

Motivtation / Agenda
- runs with coupled model have crashed due to negative salinities
- this problem was traced back to very large solid runoff fluxes around Antarctica
- in turn, this was found to be due to the runoff map for Antarctica being incorrect
- we want to improve on this so that the snowcapping scheme works right for Antarctic
- an image to give an idea of the actual ice flux (observed) is included below
- one possible option to consider would be to supply the runoff routing scheme with routing directions based on the observed or modeled ice flow
Notes
- ice / ocean team will provide river runoff team w/ ice velocity (vectors) for routing of solid runoff (Stephen Price)
- vectors to be provide on lat / lon coords.
- consider interpolating directly from MPAS-LI grid to 1/2 deg. runoff grid (need scrip file for the latter)
- land ice folks need to figure out how best to provide velocity component information (e.g., because the components will be in x,y polar stereo)
- liquid runoff CAN remain as is (using river channel network)
- to do for runoff team: need ocean domain for matching up of coastline cells (this will be specific to ocean grid)
