to use Metview with ODB?
Metview automatically recognizes both ODB-1 and ODB-2 databases formats and assigns the very same icon to them in the user interface:
The meta-data and data contents of an ODB can be inspected with the interactive ODB Examiner u Running the examine command on this icon brings up the ODB examiner to inspect the meta-data and data it contains.
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 directly visualised (and optionally filtered) in various plot types via the ODB Visualiser icon
.
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:or if only an ODB/SQL query needs to be run
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).
