connection to Lowell Drift Database
Apply for the Lowell Drift Database account to Prof. Bodo
Reinisch, Bodo_Reinisch@uml.edu. A
username and password will be issued for DriftExplorer connection to Lowell.
Make sure you have Drift Explorer version 1.2.4 or better.
The Drift-X installation page with instructions can be found here.
Configure Drift Database connection. This operation is
- Open Drift-X and
select "Database connection" from the File menu. That brings
up "Connecting to DFDB" window, with a list of available
databases in the lower panel and address editor in the upper panel. The
database list should be empty in your case, all lines should say NONE
- Select one of the
available lines in the list and click Edit button to specify our
- Enter the alias.
"Lowell DriftDB" or "UMLCAR DriftDB" seems like a
good suggestion for the alias.
- Enter Database URL jdbc:firebirdsql://18.104.22.168//ext2/db/ib/dfdb
- Provide the DriftDB
username and password.
- Click on "Save in
the list" button.
- Then click the Connect
- The window will close
and Drift-X will attempt to connect.
If the connection is successful, the title bar of the Drift-X
will have "(<database alias> is online)" added after its
version number. This connection needs to be configured only once. Next time
you start Drift-X, it will connect to the DriftDB automatically.
Catalogs and queries
- When you see "DriftDB
is online" in the title bar, you can click on the "New
Query" tool-button with the symbol of lightning (or "New
Query" from the File menu). The Drift-X will request the list of
available Digisonde stations from DriftDB. It may take some time,
depending on your location and DriftDB activity.
- The first thing to try
is perhaps the Station Tree, where we have the list of Digisonde
stations and start and end times of stored data. As you open the tree
branches, watch for the mouse pointer that turns to the sand-clock when
there is an ongoing operation. When you follow down the tree to a
particular day, you can click on the Set button to select the data for
- Then try Calendar Tree
for the list of stations available for individual days. You can also
select a particular station in the "Data Source" combo-box and
try "Current Station" button for complete inventory of data
for that station.
- You can directly
specify time interval and station in the query window. If you are not
sure whether the data are available in DriftDB, look up the data in the
catalog first (using station or calendar tree).
Read-only connection to DriftDB does not allow online
submissions of calculated skymap and velocity data to DriftDB. Please apply
for the Expert account to Prof. Bodo Reinisch, and further instructions will
be e-mailed to you.
