DALES benchmark cases ===================== RICO ---- Advection scheme 2 for mom, tke, thl, qt. 7 for sv Bulk microphysics, no radiation. ### Modifications * without custom surface scheme specified in RICO, instead using isurf=2 (Forced surface temperature; fluxes are calculated) * cloud field statistics off * sampling statistics off * cross section output on * horizontal extent changed from 128^2 to 144^2, for flexible paralellizing options ### Variants ``` namoptions-144.001 300 seconds 1 core 120.4 s on laptop namoptions-fixed.001 100 seconds 1 core fixed dt=2.5 s 133.4 s on laptop namoptions-432.001 300 namoptions-864.001 300 ``` ### Notes No clouds or rain, time is too short The fixed time step variant is useful for comparing older DALES versions, the adaptive time stepping was made more strict in version 4.2. RCEMIP ------ RRTMG radiation run every minute simpleice(2) microphysics advection scheme 5, except for qt: 77 504x504x146 cells, 200 m resolution. This is the rce_small_les case with SST=300K from the RCE-MIP model intercomparison, [Wing et al 2018](https://doi.org/10.5194/gmd-11-793-2018). ### Modifications * fielddump off * radstat off, because it assumes the radfull scheme and we are using RRTMG * supposed to be run for a long time with constant solar angle, here started at noon: xtime=43200 ### Variants ``` namoptions-96.300 96x96x146 300 s 1 core 92.7 s on laptop 1.3G RAM namoptions-504.300 504x504x146 300 s ~35 G RAM ``` ### Notes RRTMG requires data files rrtmg_lw.nc, rrtmg_sw.nc. They are currently not distributed with DALES, but can be obtained this way: ``` wget http://palm-model.org/trac/export/4419/palm/trunk/LIB/rrtmg/data/rrtmg_lw.nc wget http://palm-model.org/trac/export/4419/palm/trunk/LIB/rrtmg/data/rrtmg_sw.nc sha256sum rrtmg_*.nc 5ea5b5d4129d31952404985dc52059573f5d674cd8ee20bf5038f5e929f514a1 rrtmg_lw.nc 224aeba825ece5c53eebe97620a89fd37db6c85287aead2c624fccb80f36974e rrtmg_sw.nc ``` Ruisdael -------- RRTMG radiation, bulk (warm) microphysics, with large-scale forcings. vertical grid stretched from 20 m to 150 m, up to 13.5 km ### Variants ``` namoptions-96.001 96x96x160 15x15 km 156 m resolution 300 s 1 core 96.4 s on laptop 1.8 G RAM namoptions-192.001 192x192x160 15x15 km 78 m resolution 5 G RAM namoptions-1728.001, 1728x672x160 172x67 km 100 m resolution ``` 1728 = 64*27 672 = 32*3*7 ### Notes See above for obtaining RRTMG data. Requires DALES 4.3 or above, due to a change in large scale forcing, ltimedepuv flag. cao --- A cold air outbreak case from Stephan de Roode et al. Uses RRTMG radiation. Special for this case is that it generates clouds and precipitation from the start, so it can be used to measure how these impact the run time and distribution over the subroutines. GOAMAZON14 ---------- A case with atmospheric chemistry and RRTMG radiation, from Jordi Vila et al. Also included in cases/GOAMAZON14 with reference results. ### Variants ``` namoptions.047 36x36x200 300 s ```
