Now create a MARS Retrieval icon for the surface fields. Rename it 'ret_pl_surf', then apply the following settings:
| Param | z/2t/10u/10v |
| Level | sfc |
| Date | -1 |
| Time | 0 |
| Step | 0/12/24 |
| Area | 35/-10/65/30 |
| Grid | 1/1 |
Create another MARS Retrieval icon for the pressure level fields. Rename it 'ret_pl' and edit it in the following way:
| Param | z/t/r/u/v |
| Level | pl |
| Levelist | 1000/950/925/900/850/800/700/600/500/400/300/250/200/150/100 |
| Date | -1 |
| Time | 0 |
| Step | 0/12/24 |
| Area | 35/-10/65/30 |
| Grid | 1/1 |

Now we could save the retrieved GRIB data to disk. |
...
First, we need to ensure that Vapor Input Mode is set to 'Icon' then drop the two Mars Retrieval icons into the Vapor Input Data field.
Second, we define the list of GRIB parameters we want to see in VAPOR.
| Vapor 2d Params | z/2t/10u/10v |
| Vapor 3d Params | t/u/v/r |
| Info |

Surface geopotential (z) is converted to metres and renamed to HGT for VAPOR. |
Third, we set the vertical coordinate system:
...
We set the vertical grid type to 'Layered' and defined geopotential (z) as the parameter holding the elevation of the vertical layers (pressure levels). We also specified the vertical coordinate range (in metres) that VAPOR will display.

Internally, VAPOR Prepare converts geopotential to metres and rename it ELEVATION (this is required by VAPOR) |
...

Last, we specify the name and location of the results of the conversion:
