<li>Every hour, we receive data from Exeter, Toulouse and Offenbach.</li>
<li>Every three hours we receive data from Washington.</li>
<li>Once a day we receive data from Tokyo.</li>
<li>Every Monday from Melbourne.</li>
<li>Every first of the month from Montreal.</li>
</ul>
<p>Three kinds of data are received:</p>
<div class="highlight-python"><pre>* Observations
* GRIB fields
* Satellite images</pre>
</div>
<p>The acquisition is done in three steps:</p>
<div class="highlight-python"><pre>* The data is received from the outside world.
* The data is processed.
* The data is stored in a database.</pre>
</div>
<p>Once a day the data received the day before is extracted from the database and written into the archive.</p>
