open TELEMAC-MASCARET The mathematically superior suite of solvers

I am work on a case with relatively large domain. In this case, I need to feed the program with temporal-spatial varying meteorological data including wind, air pressure, humidity and solar radiation and so on. I have been success in reading wind and air pressure using the subroutine METEO.F provided in example wind_xy. But I am not sure how to read the other parameters even I have gone through the users' manuals for telemace3d TOMAWAC. Could any one give me a hand?

Hello,

Have you decided to use ASCII format with atmospheric data at a few locations and linear interpolation?
Do you mean you use meteo.f file from user_fortran folder?

In that case, the example is very specific to the input data, only wind is read.
If you have succeeded in reading air pressure, do the same with humidity and solar radiation, it is not so different to read (as soon as you are coherent with your input files).
After that, if you want to use them, you have to find the good variables how to store them to be used by TELEMAC-3D. For solar radiation, you have to feed RAY3 variable. For humidity, the array is HREL. In your modified METEO subroutine, add the declaration of this variable (RAY3 is already there):
USE METEO_TELEMAC, ONLY: TAIR,SYNC_METEO,RAY3,RAINFALL,HREL

To understand what atmospheric data can be used and where it is stored, you can read the $HOMETEL/sources/utils/bief/meteo_telemac.f module.

Hope this helps,

HI,Chi-Tuan,
Thank you very much for your assistance. I think I have find out the way according to the information you providing. I will try it right now.

Hi,Chi-Tuan
I have a question on the coupling among Telemac3d, TOMAWAC. I want to know whether it is necessary to feed the wheather condition to all of them or jest feed them into Telemac3d? In my case, I take the wind-induced wave in the simulation.

Hello Bert,

Since release v8p4, as written in the NEWS.txt file:
"TOMAWAC: When TOMAWAC is coupled with TELEMAC-2D or TELEMAC-3D the wind taken
into account in TOMAWAC is the one coming from TELEMAC-2D or TELEMAC-3D".

Hope this helps,

Chi-Tuan
