Outcfg.out general

General description of the file outcdf.out

General information

First one needs to define at least one type of grid, one set of levels, and one set of steps. These will then get used in the sortie (for dynamic fields) resp. sortie_p (for physics fields) declarations.

Example outcfg.out

grid=1,model;                                                               
levels=1,eta,-1;                                                             
levels=2,pres,[1000.,850.];                                                 
steps=1,hour,0.;                                                            
steps=2,step,<0.,6.,1.>;                                                    
                                                                            
sortie  ([ME,PN,P0,PT]                      ,grid, 1, levels, 1, steps, 2)  
sortie_p([MF,MY,MG,ALVIS,DLAT,DLON,WFLUX]   ,grid, 1, levels, 1, steps, 1)

Output GRID definitions

Examples:

grid=1,model;                                                               
grid=2,core;   
grid=3,free;                                                                                    

General syntax:

grid=gridid,[model/core/free];      
                                                                            
     gridid  - number to identify gridset to relate to sortie statement     
      model  - total grid of the model     
      core   - in LAM: model grid minus the pilot region
      free   - in LAM: only the free area, excluding blending (Davies sponge) and pilot area          

IMPORTANT NOTE:

    Limit the number of definitions for "grid" to improve the efficiency    
    in the output routines. The maximum number of definitions is 4.         

Output LEVEL definitions

Examples:

levels=1,eta,-1;                                                             
levels=2,eta,0;                                                             
levels=6,eta,<1,12,2>;                                                      
levels=5,pres,[1000.,850.,700.,500.];                                       

General syntax

   levels=levelid , pres/eta,{list}                                         
                                                                            
   levelid   - number to identify levelset to relate to sortie statement    
     eta - model levels (eta)                                               
         - the integer corresponds to the "nth" defined model level thus    
           make sure that the largest digit <= # of elements defined in  hyb
     pres- pressure levels                                                  
     '-1' with "eta" levels will give all model levels.                     
     '0'  with "eta" levels will give the ground "G_nk" level               
     [a,b,c] means level a,b and c are requested                            
     <a,b,c> means levels a to b, every c are requested                     
                                                                            

IMPORTANT NOTE:

    Limit the number of definitions for "level" to improve the efficiency   
    the output routines. The maximum number of definitions is 32.           
    The maximum number of levels defined in each "level" command is 201                           
                                                                            

Output FREQUENCY definitions

Examples:

steps=1,step,-1;                                                            
steps=2,hour,0.,3.,6.,12.,24.,48.;                                          
steps=3,hour,<0.,48.,3.>;                                                   
steps=4,init,hour,<0.,6.,1.>;                                               
steps=5,hour,<0.,24.,3.>,<24.,48.,6.>;                                      
steps=6,step,<0,5,1>,[6,12,18];                                             

General syntax

steps=stepid,  [init],step/hour,{list};                                     
                                                                            
    stepid  - number to identify stepset  to relate to sortie statement     
     'init' - means this command only applies to output during the          
              initialization period                                         
     'hour' - output in hours                                               
     'step' - output in timesteps in the model                              
     '-1' with "step" will give every timestep of the model                 
     [a,b,c] means a,b and c are requested                                  
     <a,b,c> means a to b, incrementing every c are requested                

IMPORTANT NOTE:

    Limit the number of definitions for "steps" to improve the efficiency   
    the output routines. It can really make a huge difference!!! 
    The maximum number of definitions is 32.           
    The maximum number of step/hour defined in each "steps" command is 50000
