Hi Seon & Ansley, I wrote 3 GO files to do the calculation of MLD variables easily. Please see the files in the attached tar file (mld_jnls.tar). Now the process of finding the MLD and a field's value just below the MLD can be done with these GO files quiet easily. Here is a small description about the 3 GO files in the attachment (for more details see the comment in the beggining of these jnl files) : mld_dens.jnl : To find MLD based on density criteria. Inputs : temp & salt , delta_T (optional) Output : mld_d mld_temp.jnl : To find MLD based on temperature criteria. (It is same is Isothermal Layer Depth, ILD) Inputs : temp , delta_T (optional) Output : mld_t mlbase_var.jnl : To find the value of a variable (say temp or salt) at the base of the given Mixed Layer. To extend the given MLD to the base of the corresponding grid cells Inputs : field to be extracted (temp/salt/dens...) and MLD Output : var_mlbase & mld_extn How to solve your problem using these jnl files ? Here is an example : yes? use levitus_climatology yes? set reg/x=30:120/y=-30:30 yes? go mld_temp temp yes? go mlbase_var temp, mld_t yes? list/x=60/y=10 mld_t yes? list/x=60/y=10 mld_extn yes? list/x=60/y=10 temp_mlbase yes? list/x=60/y=10 temp yes? fill temp_mlbase If there is any problem with these GO files or the method i used, plese let me know. Please do a consistancy check (as in the above example) before using the results. Hope this helps, Regards, Jaison On Fri, 3 Mar 2006, Ansley Manke wrote:
Hi Seon, Just a few ideas, since nobody's answered yet, I'd like to point you to the discussions of @LOC and @WEQ, and also @EVNT in the Users Guide. Also see "isosurface, example" in the Users Guide index The examples under @WEQ should give you some ideas. I haven't had time to think it through, but remember that you can use variables z[gz=var], and k[gz=var] for the coordinates and the indices of your variable. Ansley Seon Tae wrote:Hi all... I have an upper ocean temperature data. I am trying to obtain temperature at the grid points right below the MLD. Is there anyone to help me with it? Thank you very much in advance....!! -Seon Tae-
