There are two more Metview icons associated with ODB: the ODB Filter icon
that can perform an ODB/SQL query resulting in a new ODB and the ODB Visualiser icon
...
with which ODB data can be visualised (and optionally filtered) in various plot types.
Tutorial
There is a tutorial available on the use of ODB with Metview explaining both the basics of the FLEXPART simulations and the related visualisation techniques. The snapshots below showcase a few of the FLEXPART plot types that can be generated with Metview:
data using various plot types. Optionally it can perform an ODB/SQL query on the input ODB and visualises the resulting (intermediate) data. It works for both databases (ODB-1) and files (ODB-2).
From Macro/Python the icon can be called as odb_visualiser().

What is ODB?
FLEXPART is a Lagrangian particle dispersion model developed and used by a scientific community. It can be driven by meteorological input data from a variety of global and regional models including ECMWF analyses and forecasts.
The home of the software is https://www.flexpart.eu/.
What Metview version do I need for FLEXPART?
| Note |
|---|
The minimum Metview version to use is 5.0. |
How to use FLEXPART with Metview?
Metview provides a high level interface to prepare input data for FLEXPART from ECMWF's MARS archive (via the FLEXPART Prepare icon),
perform a FLEXPART simulation (via the FLEXPART Run icon)
and visualise the resulting output files. For the visualisation the gridded outputs in FLEXPART's custom binary format are converted to GRIB (click here for details).

Please note that the Metview interface was written for version 9.02 of FLEXPART. |
FLEXPART at ECMWF
FLEXPART is installed at ECMWF to be directly used from within Metview. You can find out more about it here.
FLEXPART outside ECMWF
Gallery
The Gallery features quite a few ODB related examples showcasing both the ODB Filter and ODB Visualiser icons.
Script languages
Metview provides full support for ODB from the its Macro and Python interfaces. This page summarizes the available functions while the tutorials and the Gallery examples show the concrete implementationsDetails about setting up the Metview FLEXPART interface outside ECMWF can be accessed here.
