6-month Plan: May-Oct 2013

RASM 5th WorkshopSeattle 04/13

red == high priority tasks

RASM 6-month plan #1

• VIC: bare ice albedo (Joe)• VIC ‘BART’: routing scheme to POP (Joe)• VIC: update to 4.1.2 (Bart)• VIC-GLC development & testing offline

(Jeremy+Joe)• VIC: diagnosis of the partitioning between

sensible and latent heat fluxes over land (Bart)• VIC-CN off-line for single point (Michael, Bart)

RASM 6-month plan #2• WRF: explore microphysics & radiation with two sets of

boundary conditions; 5-yr runs to diagnose/fix cloud/radiation biases in RASM (Brandon, Shelley et al - WRF)

• Continue nudging studies (i.e. higher wavenumber, only top half of atmosphere) (Mimi)

• Consider possibilities of increasing model top (Brandon, Bill)

• Sensitivity of albedo fraction in WRF (Alice, Robert)• Wind time series for sea ice (Mimi, Andrew)• Circulation bias checks in WRF /bndry precip problem

(Brandon, John)

RASM 6-month plan #3• Diagnose and fix sea ice velocity/drift problem (Andrew, Wieslaw)

– Test CICE 5.0; coupling frequency (Andrew, Tony, Alice)• Quantitatively analyze ensemble produces in RASM (Andrew, Bill,

John, Wieslaw)- Run with different reanalyses (Brandon)

• POP/CICE work with WRF output as h-compset (Alice, Andrew, Robert)

• Iterate with VIC on freshwater input to POP (Robert, Joe, Tony, Wieslaw)

• Parameter space sensitivity in RASM & h/g-compset with CORE2 forcing (Robert, Wieslaw, Andrew)

• 1/48-deg POP/CICE & 10-km WRF grid into RASM (Wieslaw, Tony, Robert, Mimi. Alice)

RASM 6-month plan #4 (Jeremy)• Enable subgridded SMB calculations, dynamic intra-elevation-

band ice/ice-free area in RASM-VIC4.1.2• Enable run-off (solid+liquid) to RASM ocean• Formulate reasonable spin-up technique for ~5m snowpack in

RASM (so reanalysis period not dominated by snowpack spin-up)

• Formulate reasonable glacier spin-up technique (so reanalysis period not dominated by glacier spin-up)

• Evaluate VIC/CLM SMB from fully-coupled simulations against RGI (observed) hypsometries

• Compare RASM-VIC SMB/climate to RASM-CLM SMB/climate• Stand-alone VIC4.1.2-GLC coupling

6-month plan: #5• CFSR/GFS forcing for RASM and compare with ERA-I results

(Brandon, Bill, Robert, Andrew, Wieslaw)• Put together boundary layer budget from all models (Andrew,

Bart, Brandon)• New Restarts: Jan 1979, 1989, 1999 & Sep 1989 (from r35rb1a h-

compset 2ica) (Robert)• 2 ensemble members for ~30 years (Andrew, Mimi)• WRF-stand alone CORDEX simulations (Justin, Shelley, John, Bill)• Validation of CESM 1.1-RASM (Andrew, Tony, Wieslaw, Bart, Alice)• Validation of Spirit port (Tony)• RASM Users Guide, include WRF averaging part (Justin, Brandon)• Steps toward GCM boundary cond’s (Brandon, Bill)

6-month plan: #6• Science domain – development of curriculum

modules (Bill R., Anna Carolina)– Design and development of delivery system– Research other agency educational materials– Formalize RASM as educational collaborative
