• Every hour, we receive data from Exeter, Toulouse and Offenbach.
• Every three hours we receive data from Washington.
• Once a day we receive data from Tokyo.
• Every Monday from Melbourne.
• Every first of the month from Montreal.

Three kinds of data are received:

* Observations
* GRIB fields
* Satellite images

The acquisition is done in three steps:

* The data is received from the outside world.
* The data is processed.
* The data is stored in a database.

Once a day the data received the day before is extracted from the database and written into the archive.

What to do:

1. Write the suite definition for this suite

Useful pointers:

• Add Trigger
• Dates and Clocks
• time
• date or day
• Repeat
• Suite Definition API

Because there is no standard unix date manipulation command, you can use ecf_date.
