The Bottom Toolbar is dynamically connected to the sidebar. The Toolbar is altered when the sidebar VIEW is changed.

• Enable/disable observation Showing observations (if available) ALL VIEWS
• Position filter apply a filter on the position list, only the positions that exist in the datasource and in the filterlist will be shown. STATION VIEW
• Show Position(DIANA) shows a big red cross in the Diana Map over the current position DATABASE AND STATION VIEW
• Connect Connect to Diana ALL VIEWS
• New directory Add a new directory for locally stored positions DATABASE AND FIELDS VIEW
• Cache query Send a query to the database to cache in the dataset (enabled if the request is too slow) DATABASE VIEW
• Record record positions while clicking at the diana Map FIELDS VIEW

The Sidebar contains the data control interface. There are three different VIEWS to access data STATIONS , DATABASE and FIELDS. At the top of the Statusbar the user can choose the datainput by the

• Diagramtype (Meteogram/Marinogram etc)
• The Model (ECMWF, Arome etc)
• The runtime of the model

The timeframe of the diagram can be selected by the start, and hours sliders at the bottom. The 0 hour refers to the runtime of the model. In case there are observations available, the time slider maybe drawn to a negative value. The label under the time sliders displays information on the closest observation site, above the sliders is information (coordinates) on the current position.

In this view, Tseries shows preprocessed point data from hdf or ASCII files. The Station lists are extracted from the current datafile and static for that file.

Since Version 5.0, Tseries is able to connect to a WDB database to retrieve data interpolated on demand. The Database-Tab title is similar to the database-server which is used in the connection.

The user interface is coordinate based, you can choose coordinates by the lat/lon sliders, write them directly into the Lat/Lon text-fields or click into any given place in the diana map to get the diagram for the specific coordinates. All the modelnames,times and coordinate borders are selected from the database. When the database connection fails, the database-tab is disabled.

The database interpolates data on demand, for this, the server has to read all the fields necessary to generate your diagram. If this is to slow (default > 1.5s) the cache button becomes active. By pushing the cache button, a request is send to the server to take all needed fields into memory - speeding up the interpolation. The caching process is running in background and takes up to one minute. It is finished when the red blinking icon vanishes.

In the Database View, stations are represented as Bookmarks (name and coordinated) Additionally to common bookmarks, the user can define a set of local bookmarks and group them into directories. First, create a new folder by the “+” button and rename the folder. Now drag positions from the other folders there, positions in the record folder can be dragged in as well. Rename the bookmarks appropriately. There are some distributed folders with given positions. These can be edited, but will be restored after restart. Private created folders will be stored locally and saved at exit All positions can be dragged into trash for removal. Empty private folders are automatically removed after restart.

Since version 6.0 Tseries is able to interpolate data from fields (netCDF,ncml etc), using the Fimex library.

To create a simple Meteogram, Tseries usually needs nine parameters ( U, V, HH , CH , CL , etc.). Assuming 66 times in a timeseries, Tseries has to interpolate in 594 FIELDS to read a single Meteogram. . Prior to interpolation, the fields are read from disk and disk and uncompressed. It may take 40 seconds to interpolate a single chart. The interpolation is very fast, most of the time is spent on retrieving data. Therefore it does not make any difference whether Tseries interpolates one chart or thousands. Because of this, Tseries interpolates all known Bookmarks immediately when data are requested, ie the user has to wait up the first time data for a certain set are requested, after that Tseries takes the interpolated data from the internal cache. Tseries reduces the data retrieval to the data needed to show the requested diagram. If the user chooses a different style, that needs additional parameters, only the missing parameters are added to the cache. Interpolation happens in a specific thread. The user can watch other diagrams meanwhile. Tseries does not allow several dataread threads. When a new position is requested, Tseries will interpolate the entire list again ( 40s latency ).

• When Tseries is connected to Diana in the Fimex view, only the positions that are visible in Tseries will be shown in Diana as well.
• The map shows a green ring around current position.

The system contains directories and sites, just like in WDB tab . The sites can be freely edited by the user :

• Create new directories by pressing the plus.
• Move positions around the directories and rename them .
• Right click to get a ' Copy , Paste , Cut, Delete “ popup-menu .
• Use standard editing keys” Ctrl - C “, ” CTRL -X “, ” CTRL - V“ and “Delete ” .
• Mark positions with the mouse or arrow keys + SHIFT or CTRL.

Local directories are saved on exit. Common directories can be altered, but they are not saved , they are reset on restart. Empty directories that are deleted automatically on exit. The local positions are stored in a file ~/.tseries/bookmarks.fimex . The file can be changed by the user to import bigger position lists
NB: all Tseries instances are sharing the same file. I.e. if several Tseries are running simultanously, the last one exiting will overwrite the lists from the others.

A single interpolation is expensive, the option to click freely on the Diana map would cost 40s each time. Because of this, there is a ” Recording Mode “, the red button at the bottom. When the “Recording Mode” is active Tseries is not reading any data. In this case the focus aims on creating new positions.

• Connect Tseries with Diana
• Select “Recording Mode”
• Click on the Diana map to select new positions
• The new positions appear in the RECORDS folder
• Move positions, rename them, etc. If necessary delete them again
• Turn off the Recording Mode

The RECORD folder is limited to 20 positions. When leaving the recording mode, the RECORD folder is automatically closed. Positions can be used directly in the RECORD folder, but the folder keeps data only temporary and is emptied on exit. No data will be interpolated for the new positions until Tseries is missing data to create a diagram.

T-series can be connected to the Diana meteorological workstation. The connection is controlled by an external application (coserver) which is socket based. Coserver starts automatically when requested. The user can connect T-series and DIANA by activate the connect button in both applications. All positions from Tseries are send to Diana and will be displayed in the map. when a position is choosen in Diana, Tseries will display the requested Diagram for that position.
