Outline

WPS• WPS V3

• NCEP FNL Operational Model Global Tropospheric Analyses, ds083.2– http://dss.ucar.edu/datasets/ds083.2/

• 1°x1° Reanalysis data, Vtable from GFS

WPS• Change in WPS/arch/configure.defaults (only first time)

– COMPRESSION_LIBS = -L/nuwa_cluster/opt/jasper-1.9/lib -L/lib64 -L/usr/lib64 \

– -ljasper -lpng12 -lpng -lz

– COMPRESSION_INC = -I/nuwa_cluster/opt/jasper-1.9/include \

– NCARG_LIBS2 = -L${PGI}/linux86-64/9.0/lib -lpgftnrtl -lpgc \

• Configure option for nuwa– source make_wps.pgi– PC Linux x86_64 (IA64 and Opteron), PGI compiler 5.2 or higher,

serial

WRFV3chemT_tracer6• Based on WRFV3.0.0.1

• All 6 tracer has the molecular mass as CO2

• Difficult while in nuwa– source make_wrf.pgi– Linux x86_64, PGI compiler with gcc (dmpar) – compile em_real; compile em_real; compile w

rf;

Fire location

Fire Hot Spot• data-P.taiwan.bin

– Point Source for smokestack– 38 indices (lat, lon, index1, index2, ht, dm, tw,

tp)

• data-AL.taiwan.bin– Line and Area source for other source– 33 indices (lat, lon, index1)

• prof.dat– Index for point and area, line source

• 180s for 45km (270s)

• 169 x 153 x 25

WRFDA• Based on WRFV3.2• 3dvar

– ./da_wrfvar.exe– This is for perturb the initial condition– Perturb U, V, T, MU, PSFC, PH, QVAPOR

• boundary– ./da_updated_bc.exe– This is for perturb the boundary (tendency) co

ndition

WRFDA• met2real.*dom.sh

– using real.exe for initial and boundary condition– Number of cycle = number of ensemble 6 hours + 1

• prepare_ICBC.csh (run_prepare.job)– run 3dvar_Member_ICBC.csh– prepare the initial and boundary condition– Generate one wrfinput_d01 and one wrfbdy_d01 for every 6 hou

rs

• 3dvar_Member_ICBC.csh– Perturb the initial and boudary condition– Use da_wrfvar.exe and pert_wrf_bc

• run_reinit.sh for cat those boundary condition files

Ensemble test run (forecast)• reinit_chem.sh (run.sh)

– Prepare the directory for ensemble run

• runWRFChem.sh– Run wrf.exe– namelist.input.wrfchem; wrfchem.job.template– Suggest 8 nodes for each job

• cap_restart– start time and end time
