A friend suggests using the webservice to get this information instead:

use Goutte\Client;

$client = new Client();

$crawler = $client->request("GET", "http://148.243.232.113:8002/webserviceSIMAT.asmx/SEDEMA");
$data = json_decode($crawler->filter('string')->text(), 'ARRAY_A');
$sedema = ['information' => $data['pollutionMeasurements']];


$crawler = $client->request("GET", "http://148.243.232.113:8002/webserviceSIMAT.asmx/METROBUS");
$metrobus_data = json_decode($crawler->filter('string')->text(), 'ARRAY_A');

$airdata = array_merge($metrobus_data['airdata'], $sedema);
