you need to provide the reference SST used when computing Q and dQdSST

If your mean about Q is surface net heat flux, i have computed it by sum of surface sensible heat flux, surface latent heat flux, surface net solar radiation (shortwave) and surface net thermal radiation (longwave) not SST?

jafar1979

1-It seems ROMS want dQdSST just when ever QCORRECTION has been defined in header file. Is it true?
2- Does it need SST data(as well as dQdSST) under this circumstances ( #define QCORRECTION)?

jafar1979

Model's SST in cold and warm regions, got much more colder and warmer results, respectively, by passing time . SWRAD, SHFLUX,SWFLUX,WINDSTERSS and RIVER are all forced which are used. About model's setup there are: DX=3.3 km TNU2 == 50.0d0 50.0d0 ! m2/s VISC2 == 10.0d0 TNUDG == 0.0d0 0.0d0 ! days ...

Dear Wilkin at first thanks for your reply. Your answer is completely correct for updated code that it has flags in ocean.in file. I have checked it when i had just one nest grid. But kate told : updated code currently only supports one parent with one child grid. No grandchildren as yet. With ...

jafar1979

Wilkin reply said that whenever UV_psource is defined, both grids need river as force file. Therefor child grid needs river data evenif it does not have any river cell. So base on ROMS structure which way is more correct when river.nc file just contains river cell's positions and data (salt, temp ...

jafar1979

Then, Is bellow set up correct when we have river just for parent grid: LuvSrc == T F ! horizontal momentum transport * LwSrc == F ! volume vertical influx * LtracerSrc == T T F F .. .. SSFNAME == /home/jafar/data/river/rivers_force_06.nc ..

jafar1979

Dear Arango sorry for same post. I cant find what I can do for above question. I hope to receive your idea about 2 follow questions 1-is there any way that refined grid does not need river data while coarse grid need? Using GRDNAME == ../data/grd_3km.nc \ ../data/grd_ref1.nc ININAME == ../data/CS ...

jafar1979

Base on your post i have set LtracerSrc == T T F F !there are river cells just in parent grid NFFILES ==5 4 ! number of forcing files FRCNAME == /home/jafar/data/Forcing/CS_shflux2_era_06.nc \ /home/jafar/data/Forcing/wind2stress/CS_wind2stress_06.nc \ /home/jafar/data/Forcing/CS_swflux2_era_06.nc ...

jafar1979

Dear Arango
many many thanks. i found my answer with your nice post.
cheers
jafar

jafar1979

Your answer will make me sure about what i have done.
Cheers
jafar

jafar1979

1-please tell me that if initial condition provide by netcdf file, parent and child need their own initial files, separately?
2-with regard that in NFFILES just number of parent's force files is set: should number of force files for parent and child be same ?

jafar1979

many thanks for your reply

jafar1979

is your mean from "deeper Tcline", greater TCline from hmin?
for example is it possible to have : TCline= 6 , hmin=5.

jafar1979

1-is it possible that TCLINE be less than hmin, when Vtransform=2 and Vstretching=4?
2- with regard that created nest grid does not have TCLINE as a variable, how can determined appropriate TCLINE for refined grid?

Dear when I compile my coupled test with WEC_VF it has no problem but when I compile it with WEC_MELLOR it gives error: cd /home/test/Build; /home/program/mpich-3.0.4/bin/mpif90 -c -frepack-arrays -g -fbounds-check -I/home/program/mct/include -I/usr/include wetdry.f90 cd /home/test/Build; /home ...

jafar1979

dear
i have faced with

Code: Select all

MCT::m_MCTWorld::initm_MCTERROR:  MCTWorld has already been initialized...Continuing

SWAN grid   2 is preparing computation

MCT::m_MCTWorld::initm_MCTERROR:  MCTWorld has already been initialized...Continuing

but model has run.is it important?
thanks for any reply

Dear warner in roms model when we have different files for one variable we use | sign at the end of it. But what about in COAWST. When i use wind_year1.nc | wind_year2.nc\ it gives me error that cant find input file? Would you please tell me how i can define this separate files in COAWST model ...

jafar1979

at first thanks for your reply All forces of mine are for 365/366 days per year, and i want to run model for 5 years. So if cycle_length be 360, climatology's fields will shift about five days per year and after 5 years, climatology season will shift to Early days of previous month . Therefore it ...

jafar1979

Dear friend one question of mine is about cycle_length. What cycle_length do in climatology file? Does it mean that climatology fields will repeat for latter years with 360 or 365.25 days as a cycle? or clomatology data are just for first year? Also i can not completely find that what different ...

jafar1979

when there are yearly input files (for example wind_2004.nc and wind_2005.nc), further year's wind_time should be continuation of former year's wind_time or started from the beginning? For example when we have: NFFILES == 2 FRCNAME == wind_2004.nc\ wind_2005.nc/ river_2004.nc\ river_2005.nc/ which ...

jafar1979

Dear kate thanks for your answer. but about second question. i have seen (in https://www.myroms.org/wiki/index.php/Options) for some options: when a is b's conflict, b is a's conflict, too. but for others it doesn't happen. For example uv_LDRAG and uv_QDARG are each other conflict. But for UV_QDRAG ...

jafar1979

dear Kate I have 2 questions about options which they are conflict with each other. First one: should not those options be defined in header file simultaneously? If yes why in your branch ((https://github.com/kshedstrom/roms/tree/kate_svn/Apps/Caspian) ana_ssflux and EMINUSP defined in caspian.h ...

jafar1979

Dear Kate
thanks as usual.
It is possible to sent mentioned Matlab script for me or sent its link . I usually use Matlab as a scripting language.
Thanks
have a nice holiday

Dear Prof. Arango
many thanks for your complete information.
i know that you are so busy but if it is possible for you would you please tell me what kind of process on the ERA fields to get the correct force for ROMS is needed.
Because i use ERA into ROMS directly.
Cheers
jafar

jafar1979

Dear Prof.Arango i guess that time unit of force file which created by d_ecmwf2roms.m should be hours not days :?: . My reason is :created force file have time size equal to 3hourly ecmwf data (both of them have 2920 time steps for one year), Therefore their units should be equal too?is not it? S ...

jafar1979

dear
base on your experience what the best value for wave-ocean coupling interval is? for determining it, user should attention to what?

jafar1979

dear m567tej thanks for your kindly reply. actually i used 1 processor for ROMS and 1 processor for SWAN but that error appear. also i did not make change into ROMS grid file. i think you use COAWST which has SWAN40.91. is not it? because as Warner said in Rutgers version (SWAN40.51) there is such ...

jafar1979

dear Warner about my last post: At line 420 of file ocpids.f90 Fortran runtime error: Actual string length is shorter than the declared one for dummy argument 'timstr' (15/24) swan model break when it what to give current from ROMS model. i check ocpids.f90 file (and ocpids.F) it includes ...

jafar1979

Dear Warner many many thanks i can not believe that my fault is long path name. now Swan is preparing computation. but recent error is: at line 420 of file ocpids.f90 Fortran runtime error:actual string length is shorter than the declared one for dummy argument 'timstr' (15/24) base on NTIMES=34560 ...

jafar1979

hi i guess that bug in mpich2 release 1.4.1p1 cause above problem, therefore i installed release 3.0.4 but it can not help me. as i told before when more that 1 cpu used for swan, PRINT or ERR* files are empty but when 1 cpu used for it, there is input file missing error in those files and in ...

jafar1979

dear Warner i am sure that MPICH2 (release 1.4.1p1 )installation was correct /configure FC=gfortran CC=gcc --prefix=/home/<user>/mpich2_install_new 2>&1 |tee c.txt make 2>&1 |tee m.txt make install 2>&1 |tee mi.txt because i was able to run upwelling test in parallel mode successfully. and about MCT ...

jafar1979

dear all in inlet test's header file, there is ANA_INITIAL that shows in this test analytically initial condition used. but in test folder which is in ROMS site, there is inlet_init.nc :?: . does inlet_init.nc file have another meaning than initial condition? please tell me this netcdf file is as a ...

Dear kate Thanks for your reply. I got NaN values when open history file with matlab by: ncdisp('ocean_his','u'); u=ncread('ocean_his','u') But with ncdump it has some things like: -,-,-, Sorry but I can not completely find what you say. I have plotted by csec and ccnt and checked salinity and temp ...

jafar1979

dear after running latte test successfully, i tried to plot its out put. i saw that every variable in history file, has _FillValue (equal to 1 e+37). i know that in latte test masking option is defined and results in land area should be NAN but would you please tell me what _FillValue do? also i ...

jafar1979

dear i have installed MCT source only (with out data)and put its include and lib directories in linux_gfortran.mk file as: MCT_INCDIR?=/home/<user>/MCT/include MCT_LIBDIR?=/home/<user>/MCT/lib FFLAGS+=-I$(MCT_INCDIR) LIB+=-L$(MCT_LIBDIR) -lmct -lmpeu (2 lat line with out change) but in above post i ...
