Specifies the data input mode. The possible values are: Icon and Path. The default value is Icon.

In Icon mode a set of GRIB icons has to be specified in Vapor Input Data. If the mode is set to Path a period with a start and end date and constant time-step can be defined. In this case FLEXTRA Prepare tries to retrieve analysis fields from MARS whenever it is possible (for dates in the past) and uses forecast fields otherwise (for dates in the future the input data is read from a specified path on the filesystem  (yet to be implemented).

Vapor Input Data

Specifies the input data as a set of GRIB icons. It is available when Vapor Input Mode is Icon.

...

Specifies the type of the 3D data to be used in VAPOR. The possible values are: Layered and Regular. The default value is Layered.

If the type is set to Layered VAPOR expects a parameter specifying the elevation of each 3D level in the input data. This is typically the case for pressure or model level (η levels) input data.

For the Regular type the

The default value is Layered.

Vapor Elevation Param

Specifies the short name of the 3D parameter interpreted as the elevation of the 3D levels. Available when Vapor Vertical Grid Type is Layered.

This parameter has to be either the height or the geopotential (z) of the levels. If geopotential is specified it is converted into metres by Metview for Vapor. The default value is z.

titleModel LevelsDerive eleveation for model levels

Please note that neither the height nor the geopotential of model levels are archived in MARS. It means that for model level data either of these fields has to be computed for Layered mode. These computations can be done internally in VAPOR Prepare by simply specifying z for Vapor Elevation Param. The computations can only be done if the input data contains temperature (t) and specific humidity (q) on model levels and geopotential (z) and logarithmic of surface pressure (lnsp) on the bottommost model level.

...

The name of the upper level GRIB parameter interpreted as the elevation of the upper levels. Available when Vapor Vertical Grid Type is Layered.

Vapor Area Selection

Specifies the data input mode. The possible values are: Native and Interpolate. The default value is Native.

If it is set to Native


The name of the upper level GRIB parameter interpreted as the elevation of the upper levels. Available when Vapor Vertical Grid Type is Layered.

...

Specifies the area of the output grid in south/west/north/east format. The default value is  -90/-180/90/180. Available when Vapor Area Selection is Interpolate.

Vapor Grid

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 degrees units). The default value is: 1/1. Available when Vapor Area Selection is Interpolate.

Vapor Refinement Level

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 degrees units). The default value is: 1/1.
