Perl

 Below is a simple Perl script making use of the ECMWF::DataServer module: 

#!/usr/bin/env perl
use ECMWF::DataServer;

my $server = ECMWF::DataServer->new();

$server.retrieve({
    'dataset' : "tigge",
    'step'    : "24/to/120/by/24",
    'number'  : "all",
    'levtype' : "sl",
    'date'    : "20071001/to/20071003",
    'time'    : "00/12",
    'origin'  : "all",
    'type'    : "pf",
    'param'   : "tp",
    'area'    : "70/-130/30/-60",
    'grid'    : "2/2",
    'target'  : "data.grib"
    })

 Choosing a dataset

The "dataset" parameter is one of:

<table id="datasets_table"></table>
<script src="https://api.ecmwf.int/static/api/build_dataset_table.js"></script>
<script>
build_dataset_table($("#datasets_table"));
</script>

  To access these dataset, you need to agree on the  the corresponding terms and conditions that can be found under the "Licence" link in the table above. See http://apps.ecmwf.int/datasets/ for the content of the datasets. The other parameters are described at: http://www.ecmwf.int/publications/manuals/mars/guide/index.html

Proxies

 This tool is based on the python module urllib2, and therefore use the http_proxy and https_proxy environment variables if they are set. You should set these variables in your Unix shell if your organisation runs an outgoing proxy.
