The macro language equivalent is met3d_prepare().


...

Specifies the list of model levels when Levtype is ml. The default value is: -10.

Analysis End Date

...

Specifies the end time of the period. Available when Mode is period analysis. The default value is 0.

Analysis Step

Specifies the time step of the analysis period in hours. The allowed values are as follows:  6 or 12. Available when Mode is period analysis. The default value is 6.

Area

...

Specifies the resolution of the output grid in dx/dy format, where dx is the grid increment in east-west direction, while dy is the grid increment in north-south direction (both in units of degrees). The default value is: 1/1.

Retrieve Group By Time 

Specifies how the MARS retrievals should be executed. When it is set to ON the following happens:

...

When it is set to OFF each step/time is retrieved separately (in  in a loop). The default value is ON.
