Info
titleTrajectory types and levels

We set the trajectory type by its ID. The possible values are as follows:

  1. Three-dimensional
  2. Model layer
  3. Mixing layer
  4. Isobaric
  5. Isentropic

The level units were also given by an ID. The possible values are as follows:

  1. Metres above sea level
  2. Metres above ground levelevel
  3. Hectopascals

Parameter Flextra Output Interval Mode controls how the trajectory points are written out into the output file. It can have three values:

...

To start with, we have to be aware that Metview assigns an integer ID to each trajectory before it gets visualised. The numbering starts at 1 and the original trajectory order is kept. In this way we assign thevalue the value of 1 to all the points in the first trajectory. We assign the value of 2 to the points if the second trajectory and so on for the rest of the trajectories. Then in the visualisation Metview uses symbol plotting to assign different graphical attributes to different values i.e. for different trajectories.

The FLEXTRA Prepare Icon

The  FLEXTRA Prepare - old icon is used to generate all the input data needed for a FLEXTRA run including the MARS retrievals, the computations and the generation of the AVAILABLE file as well.
